NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- ------------------------------------------

A.   OPINION OF MANAGEMENT

Financial information furnished herein, which is unaudited, in the opinion of
management reflects all adjustments (all of which are of a normal recurring
nature) that are necessary to present a fair statement of the interim period.
This unaudited interim information should be read in conjunction with the
Company's annual Form 10-K filing for the year ended December 31, 2004.


B.   RECLASSIFICATIONS

Certain reclassifications have been made to prior years' amounts to conform with
current year classifications. These reclassifications relate principally to
components of the Consolidated Statements of Cash Flows. As a result of these
reclassifications, certain 2004 amounts presented for comparative purposes will
not individually agree with previously filed Forms 10-K or 10-Q.


C.   OPTIONS FOR COMMON STOCK

In prior years, when stock options were issued to employees, the Company used
the intrinsic value method to account for the options. No compensation expense
was recognized on the grant date, since at that date, the option price equaled
the market price of the underlying common stock. Effective in 2003, the Company
ceased granting stock options to employees. In 2004, the Management Development
and Compensation Committee of the Board of Directors approved the granting of
restricted stock units as the long-term equity component of officer
compensation. In the first quarter of 2005, the Company issued 32,700
performance-based restricted stock units with a fair value of $50.41 per unit to
certain officers. Restricted stock units are more fully described in Note 12,
"Stock-Based Compensation," to the Company's Form 10-K for the year ended
December 31, 2004.

The Company's net income and net income per common share would have been reduced
to the pro forma amounts indicated below if compensation cost for the Company's
stock option plan had been determined based on the fair value at the grant date
for awards in accordance with the provisions of SFAS No. 123, "Accounting for
Stock-Based Compensation" (SFAS 123).


                                                                    THREE MONTHS ENDED

E.   ACCOUNTS RECEIVABLE AND INVENTORIES

Accounts receivable are net of an allowance for doubtful accounts of $16.8
million and $19.1 million at March 31, 2005 and December 31, 2004, respectively.
The decrease in the allowance for doubtful accounts is due principally to the
write-off of previously reserved accounts receivable. The provision for doubtful
accounts was $1.3 million and $1.7 million for the three months ended March 31,
2005 and 2004, respectively.

Inventories increased $30.8 million from December 31, 2004 due to the following
factors: increased work-in-process and raw materials inventories due primarily
to long-lead-time orders currently being manufactured at the railway track
maintenance services and equipment business, but not scheduled for delivery
until the second half of 2005; increased finished goods for the international
Access Services and Gas Technologies businesses to meet expected demand in the
second and third quarters of 2005.

H.   ASSETS HELD FOR SALE AND DISCONTINUED OPERATIONS

In management's ongoing strategic efforts to increase the Company's focus on
core industrial services, certain manufacturing operations have been divested.
Effective March 21, 2002, the Board of Directors authorized the sale of the
Capitol Manufacturing business, a business unit of the Gas Technologies Segment.
A significant portion of the Capitol Manufacturing business was sold on June 28,
2002. The Company continues to recognize income from inventory consigned to the
buyer in accordance with the sale agreement and when all revenue recognition
criteria have been met. This business has been included in Discontinued
operations in the Consolidated Statements of Income and the assets and
liabilities have been separately identified on the Consolidated Balance Sheets
as "held for sale" for all periods presented. There were no sales from
Discontinued operations for the three months ended March 31, 2005 and 2004 as
the business was sold during 2002. The income from Discontinued operations does
not include any charges to reduce the book value of the business held for sale
to its fair market value less cost to sell, since the fair value of the business
exceeded the book value.

Throughout 2004, management approved the sale of certain long-lived assets
(primarily land and buildings) of the Mill Services Segment. Accordingly, these
assets have been separately identified on the Consolidated Balance Sheets as
"held for sale" for all periods presented. No additional assets were classified
as "held for sale" during the first quarter of 2005.

I.   COMMITMENTS AND CONTINGENCIES

ENVIRONMENTAL
The Company is involved in a number of environmental remediation investigations
and clean-ups and, along with other companies, has been identified as a
"potentially responsible party" for certain waste disposal sites. While each of
these matters is subject to various uncertainties, it is probable that the
Company will agree to make payments toward funding certain of these activities
and it is possible that some of these matters will be decided unfavorably to the
Company. The Company has evaluated its potential liability, and its financial
exposure is dependent upon such factors as the continuing evolution of
environmental laws and regulatory requirements, the availability and application
of technology, the allocation of cost among potentially responsible parties, the
years of remedial activity required and the remediation methods selected. The
Consolidated Balance Sheets at both March 31, 2005 and December 31, 2004
included accruals of $2.7 million for environmental matters. The amounts charged
against pre-tax income related to environmental matters totaled $0.3 million and
$0.4 million for the first three months of 2005 and 2004, respectively.

The liability for future remediation costs is evaluated on a quarterly basis.
Actual costs to be incurred at identified sites in future periods may vary from
the estimates, given inherent uncertainties in evaluating environmental
exposures. The Company does not expect that any sum it may have to pay in
connection with environmental matters in excess of the amounts recorded or
disclosed above would have a material adverse effect on its financial position,
results of operations or cash flows.

In January 2002, the New Jersey Department of Environmental Protection ("NJDEP")
issued Notices of Civil Administrative Penalty Assessment to the Company for
violations of the New Jersey Air Pollution Control Act. The Notices allege that
the Company operated a slag processing plant in violation of the emission permit
for control of slag dust. The Agency assessed civil administrative penalties
totaling approximately $311,000 and the Company filed an appeal with the Agency.
In March 2003, NJDEP amended its assessment and reduced the proposed penalty to
$146,000. In August 2004, NJDEP amended its reassessment of $146,000 and revised
the proposed penalty to $325,400. The amended order has been appealed.
Discussions continue between the parties to resolve this matter. The Company
ceased operations at the plant in the fourth quarter of 2001 for unrelated
reasons.

ROYALTY EXPENSE DISPUTE
The Company is involved in a royalty expense dispute with Canada Revenue Agency
(CRA). The CRA is proposing to disallow certain royalty expense deductions
claimed by the Company's Canadian subsidiary on its 1994-1998 tax returns. As of
March 31, 2005, the maximum assessment from the CRA for the period 1994-1998 is
approximately $9 million including tax and interest. The Company has filed an
administrative appeal and will vigorously contest the disallowance.

The Company currently anticipates that some portion of the assessment may be
paid in this royalty expense dispute. However, the Company intends to utilize
competent authority proceedings in the U.S. to recover a portion of any required
tax payment amount. The Company believes that any amount not recovered through
these proceedings has been fully reserved as of March 31, 2005, and therefore
will not have a material adverse affect on the Company's future results of
operations.

OTHER
The Company has been named as one of many defendants (approximately 90 or more
in most cases) in legal actions alleging personal injury from exposure to
airborne asbestos over the past several decades. In their suits, the plaintiffs
have named as defendants many manufacturers, distributors and installers of
numerous types of equipment or products that allegedly contained asbestos.

The Company believes that the claims against it are without merit. The Company
has never been a producer, manufacturer or processor of asbestos fibers. Any
component within a Company product which may have contained asbestos would have
been purchased from a supplier. Based on scientific and medical evidence, the
Company believes that any asbestos exposure arising from normal use of any
Company product never presented any harmful airborne asbestos exposure, and
moreover, the type of asbestos contained in any component that was used in those
products is protectively encapsulated in other materials and is not associated
with the types of injuries alleged. Finally, in most of the depositions taken of
plaintiffs to date in the litigation against the Company, plaintiffs have failed
to identify any Company products as the source of their asbestos exposure.

The majority of the asbestos complaints have been filed in either New York or
Mississippi. Almost all of the New York complaints contain a standard claim for
damages of $20 million or $25 million against the approximately 90 defendants,
regardless of the individual's alleged medical condition, and without
identifying any Company product as the source of plaintiff's asbestos exposure.
With respect to the Mississippi complaints, most contain a standard claim for an
unstated amount of damages against the numerous defendants (typically 240 to
270), without identifying any Company product as the source of plaintiff's
asbestos exposure.

The Company has not paid any amounts in settlement of these cases, with the
exception of two settlements totaling less than $10,000 paid in 1998 from
insurance proceeds. The Company's insurance carrier has paid all legal costs and
expenses to date. The Company has liability insurance coverage available under
various primary and excess policies that the Company believes will be available
if necessary to substantially cover any liability that might ultimately be
incurred on these claims.

As of March 31, 2005, there are 31,784 pending asbestos personal injury claims
filed against the Company. Of these cases, 26,510 were pending in the New York
Supreme Court for New York County in New York State and 4,988 of the cases were
pending in state courts of various counties in Mississippi. The other claims
totaling approximately 286 are filed in various counties in a number of state
courts, and in certain Federal District Courts, and those complaints assert
lesser amounts of damages than the New York cases or do not state any amount
claimed.

As of March 31, 2005, the Company has obtained dismissal by stipulation, or
summary judgment prior to trial, in all cases that have proceeded to trial. To
date, the Company has been dismissed from 9,677 cases.

In view of the persistence of asbestos litigation nationwide, which has not yet
been sufficiently addressed either politically or legally, the Company expects
to continue to receive additional claims. However, there were developments
during the fourth quarter of 2002 that could have a favorable effect for the
Company regarding the pending claims and the number of future claims filed in
the New York Supreme Court for New York County and in Mississippi state courts
after 2002. On December 19, 2002, the New York Supreme Court responsible for
managing all asbestos cases pending within New York County issued an Order which
created a Deferred or Inactive Docket for all pending and future asbestos claims
filed by plaintiffs who cannot demonstrate that they have a malignant condition
or discernible physical impairment, and an Active Docket for plaintiffs who are
able to show such medical conditions. The Court is reviewing cases for docketing
based on their date of filing, with the older pending cases reviewed first.
Cases designated as Active are then assigned to a "FIFO" trial group, which
groups are scheduled for trial in the designated months of either February or
August. For cases in which there has been a recent death or a diagnosis of
cancer, the Court reviews such cases on an expedited basis and, if medically
supported, such cases are transferred to an "In Extremis" trial group, which
groups are scheduled for trial in the designated months of either May or
November. As of March 31, 2005, the Company was listed as a defendant in
approximately 163 pending cases in the New York Supreme Court for New York
County that have been designated as Active or "In Extremis" and assigned to
trial groups. To date, the Company has been dismissed as a defendant prior to
trial in all New York cases that have proceeded to trial. The number of these
dismissals is currently approximately 1,231.

Also, in the fourth quarter of 2002, Mississippi enacted tort reform legislation
that made various changes in the law favorable to the Company's defense and that
will apply to all cases filed on or after January 1, 2003. The majority of the
claims pending against the Company in Mississippi were filed in the fourth
quarter of 2002, in advance of the effective date of this more restrictive
legislation.

During the first quarter of 2005, the Company obtained a significant number of
case dismissals in Mississippi. These dismissals were in the wake of the
Mississippi Supreme Court's decision in the Mangialardi case (in which the court
held that consolidation of personal injury claims is impermissible and that
restricted out of state residents from bringing asbestos suits in Mississippi).
Based on these dismissals, the total number of pending Mississippi cases as of
March 31, 2005 is now 4,988. Significantly, however, 2,879 of those cases were
filed in, or removed to, the Mississippi federal district court, which is in the
process of transferring them to the federal Multidistrict Asbestos Docket in
Philadelphia (the "MDL"). In accordance with an order of the MDL court entered
several years ago, the transferred cases are deemed "administratively
dismissed," subject to being reinstated only when each individual plaintiff can
demonstrate both a present physical injury and that asbestos exposure resulted
from the products or activities of identifiable defendants. These
"administratively dismissed" cases are not included in the dismissal numbers
noted in the above paragraphs.

The Company intends to continue its practice of vigorously defending these cases
as they are listed for trial and expects the insurance carriers to continue to
pay the legal costs and expenses. Management believes that the outcome of these
cases will not have a material adverse effect on the Company's financial
condition, results of operations or cash flows.

The Company is subject to various other claims and legal proceedings covering a
wide range of matters that arose in the ordinary course of business. In the
opinion of management, all such matters are adequately covered by insurance or
by accruals, and if not so covered, are without merit or are of such kind, or
involve such amounts, as would not have a material adverse effect on the
financial position, results of operations or cash flows of the Company.

Defined benefit pension expense in the first quarter of 2005 was $1.0 million
lower than the comparable 2004 period. This decrease relates primarily to a
decline in the Company's U.K. pension expense as a result of plan changes
implemented effective January 1, 2004.

In the quarter ended March 31, 2005, the Company contributed $0.2 million and
$14.9 million for the U.S. and international defined benefit pension plans,
respectively. This includes a $9.4 million voluntary contribution to the
Company's U.K. pension plan. The Company currently anticipates contributing an
additional $0.7 million and $15.4 million for the U.S. and international plans,
respectively, during the remainder of 2005.

     =========================================================================================================


The curtailment gains of $0.3 million for 2005 and $0.7 million for 2004 were
due to the termination of certain postretirement health care plans.

In the quarter ended March 31, 2005, the Company contributed $67 thousand to the
postretirement plans and anticipates contributing approximately $253 thousand
during the remainder of 2005.

L.   INCOME TAXES

The effective income tax rate relating to continuing operations was 32.3% in the
first quarter of 2005. This compares with 31.0% in the first quarter of 2004.
This increase in the effective income tax rate in 2005 was primarily a result of
the expiration of three tax holidays; one in Europe, one in the Middle East and
one in Asia.

On October 22, 2004, the American Jobs Creation Act (AJCA) was signed into law.
The AJCA includes a deduction of 85% for certain international earnings that are
repatriated to the U.S., as defined in the AJCA. The Company may elect to apply
this temporary provision to qualifying earnings repatriations during 2005. On
January 13, 2005, the U.S. Treasury Department and the U.S. Internal Revenue
Service (IRS) issued the first in a series of notices that will provide detailed
guidance on the AJCA. On April 18, 2005 the IRS stated that they are working to
finalize certain issues and release the second round of guidance. The Company is
assessing the effects of the repatriation provision and expects to complete its
evaluation within a reasonable period of time following the publication of
additional guidance by the U.S. Treasury Department and IRS, as well as the
possible action by Congress to enact technical corrections. A specific range of

income tax effects of these repatriations has not been determined; however, the
Company does not expect a significant impact due to the structure of its
international operations as well as the substantial amount of repatriations to
the U.S. in prior years.

M.   NEW FINANCIAL ACCOUNTING STANDARDS ISSUED

SFAS No. 123 (revised 2004), "Share-Based Payment" (SFAS 123R)
- --------------------------------------------------------------

In December 2004, the Financial Accounting Standards Board (FASB) issued SFAS
123R which replaces SFAS No. 123, "Accounting for Stock-Based Compensation" and
supersedes Accounting Principles Board (APB) Opinion No. 25, "Accounting for
Stock Issued to Employees" (APB 25). SFAS 123R requires the cost of employee
services received in exchange for an award of equity instruments to be based
upon the grant-date fair value of the award (with limited exceptions).
Additionally, this cost is to be recognized as expense over the period during
which an employee is required to provide services in exchange for the award
(usually the vesting period). SFAS 123R eliminates APB 25's intrinsic value
method which the Company has historically used to account for stock option
grants.

In March 2005, the Securities and Exchange Commission (SEC) issued Staff
Accounting Bulletin No. 107 (SAB 107) which summarizes the views of the SEC
staff regarding the interaction between SFAS 123R and certain SEC rules and
regulations. SAB 107 provides guidance on several topics including: valuation
methods, the classification of compensation expense, capitalization of
compensation cost related to share-based payment arrangements, the accounting
for income tax effects of share-based payment arrangements, and disclosures in
Management's Discussion and Analysis subsequent to adoption of SFAS 123R.

In April 2005, the SEC issued FR-74, "Amendment to Rule 4-01(a) of Regulation
S-X Regarding the Compliance Date for Statement of Financial Accounting
Standards No. 123 (Revised 2004), SHARE-BASED PAYMENT" (FR-74). FR-74 allows
companies to implement SFAS 123R at the beginning of their next fiscal year
(January 1, 2006 for the Company), instead of the next reporting period that
begins after June 15, 2005. FR-74 does not change the accounting required by
SFAS 123R; it only changes the required implementation date of the standard.

The Company has not yet determined the full impact of implementing SFAS 123R,
but it is not expected to have a material impact on the Company's financial
position, results of operations or cash flows since the Company ceased granting
stock options in 2003. The Company plans to implement SFAS 123R as of January 1,
2006.

SFAS No. 151, "Inventory Costs, an amendment of ARB No. 43, Chapter 4" (SFAS
- ----------------------------------------------------------------------------
151)
- ----

In November 2004, the FASB issued SFAS 151, which amends Accounting Research
Bulletin No. 43, Chapter 4 "Inventory Pricing" (ARB 43). SFAS 151 clarifies that
abnormal amounts of idle facility expense, freight, handling costs and wasted
material (spoilage) should be expensed rather than capitalized as inventory.
Additionally, SFAS 151 requires that allocation of fixed production overheads to
inventory costs be based upon the normal capacity of the production facility.
The provisions of SFAS 151 are applicable to inventory costs incurred during
fiscal years beginning after June 15, 2005 (as of January 1, 2006 for the
Company) with earlier application permitted. The Company has not yet determined
the full impact of SFAS 151; however, it is not expected to materially impact
the Company's financial position, results of operations or cash flows. The
Company plans to implement SFAS 151 effective January 1, 2006.

SFAS No. 153, "Exchanges of Nonmonetary Assets, an amendment of APB Opinion No.
- -------------------------------------------------------------------------------
29" (SFAS 153)
- --------------

In December 2004, the FASB issued SFAS 153 which eliminates the exception from
fair value measurement for nonmonetary exchanges of similar productive assets in
paragraph 21(b) of APB Opinion No. 29, "Accounting for Nonmonetary
Transactions," and replaces it with an exception for exchanges that do not have
commercial substance. SFAS 153 specifies that a nonmonetary exchange has
commercial substance if the future cash flows of the entity are expected to
change significantly as a result of the exchange. The provisions of SFAS 153 are
applicable for nonmonetary asset exchanges occurring in fiscal periods beginning
after June 15, 2005 (as of July 1, 2005 for the Company) with earlier
application permitted. The Company has not yet determined the full impact of
SFAS 153; however, it is not expected to materially impact the Company's
financial position, results of operations or cash flows as the Company has
historically had a very limited number of nonmonetary exchange transactions. The
Company plans to implement SFAS 153 effective July 1, 2005.

FASB Interpretation No. 47, "Accounting for Conditional Asset Retirement
- ------------------------------------------------------------------------
Obligations, an interpretation of FASB Statement No. 143" (FIN 47).
- -------------------------------------------------------------------

In March 2005, the FASB issued FIN 47 which clarifies that the term "conditional
asset retirement obligation" as used in SFAS No. 143, "Accounting for Asset
Retirement Obligations" (SFAS 143), refers to a legal obligation to perform an
asset retirement activity in which the timing and/or method of settlement are
conditional on a future event that may or may not be within the control of the
entity. The obligation to perform the asset retirement activity is unconditional
even though uncertainty exists about the timing and/or method of settlement.
Accordingly, an entity is required to recognize a liability for the fair value
of a conditional asset retirement obligation if the fair value of the liability
can be reasonably estimated. The fair value of a liability for the conditional
asset retirement obligation should be recognized when incurred--generally upon
acquisition, construction, or development and/or through the normal operation of
the asset. Uncertainty about the timing and/or method of settlement of a
conditional asset retirement obligation should be factored into the measurement
of the liability when sufficient information exists. FIN 47 also clarifies when
an entity would have sufficient information to reasonably estimate the fair
value of an asset retirement obligation. FIN 47 is effective no later than the
end of fiscal years ending after December 15, 2005 (December 31, 2005 for the
Company). The Company has not yet determined the full impact of implementing FIN
47, but it is not expected to have a material impact on the Company's financial
position, results of operations or cash flows. The Company plans to implement
FIN 47 by December 31, 2005.

EXECUTIVE OVERVIEW
The Company's first quarter 2005 revenues were a first quarter record $640.1
million. This is an increase of $83.8 million or 15% over the first quarter of
2004. Income from continuing operations was $23.1 million for the first quarter
of 2005 compared with $16.9 million in the first quarter of 2004, an increase of
37%. Diluted earnings per share from continuing operations were a first quarter
record $0.55 compared with $0.41 for the first quarter of 2004, a 34% increase.

The first quarter of 2005 results were led by a strong performance from the
Access Services Segment and all businesses in the Engineered Products and
Services ("all other") Category. The Mill Services Segment also had improved
revenues and operating income while the Gas Technologies Segment had improved
revenues but decreased operating income.

Revenues for the first quarter of 2005 for the Mill Services Segment were $268.6
million compared with $236.3 million in the first quarter of 2004, a 14%
increase. Operating income for the first quarter of 2005 increased by 7% to
$27.0 million, from $25.3 million in the first quarter of 2004. The Mill
Services business accounted for 42% of the Company's revenues

                                      -15-

                         PART I - FINANCIAL INFORMATION

and 57% of the operating income for the first quarter of 2005. Operating margins
for this Segment declined by 60 basis points to 10.1% from 10.7% in the first
quarter last year due to higher energy, maintenance and start-up costs. Mill
Services growth is expected to continue as worldwide steel mill production
volume is projected to remain strong in the near-term, and as the Company
invests substantial cash to grow the business.

The Access Services Segment's revenues in the first quarter of 2005 were $183.6
million compared with $157.8 million in the first quarter of 2004, a 16%
increase. Operating income for the first quarter of 2005 increased by 275% to
$9.4 million, from $3.4 million in the first quarter of 2004. The Access
Services business accounted for 29% of the Company's revenues and 20% of the
operating income for the first quarter of 2005. Operating margins for the
Segment improved by 290 basis points to 5.1% from 2.2% in the first quarter of
last year due to product mix and increased equipment rentals. Improved
performance was achieved by both the international and domestic Access Services
operations.

The Gas Technologies Segment revenues in the first quarter of 2005 were $82.1
million compared with $77.6 million in the first quarter of 2004, a 6% increase.
Operating income was $2.1 million for the first quarter of 2005 compared with
$3.1 million for the first quarter of 2004. The increased revenues in the first
quarter of 2005 were led by the cryogenics equipment, industrial cylinder and
composite cylinder businesses. Although revenue increased, operating income and
operating margins for the first quarter of 2005 declined in comparison with the
first quarter of 2004 due to higher operating costs and customer pre-buying of
propane tanks that occurred in last year's first quarter in anticipation of
future price increases. Additionally, reduced demand for certain valves
negatively impacted operating income in the first quarter of 2005.

Four of the five businesses in the Engineered Products and Services ("all
other") Category contributed higher revenues in the first quarter of 2005
compared with the first quarter of 2004. All five businesses showed improvements
in operating income and margins in comparison to the first quarter of 2004, with
the industrial grating products and air-cooled heat exchangers businesses
achieving the largest increases.

The positive effect of foreign currency translation increased first quarter 2005
consolidated revenues by $15.6 million and pre-tax income by $1.3 million when
compared with the first quarter of 2004.

The Company's operations span several industries and products as more fully
discussed in Part I, Item 1, "Business," of the Company's Form 10-K for the year
ended December 31, 2004. On a macro basis, the Company is affected by worldwide
steel mill production and capacity utilization; non-residential construction and
industrial maintenance activities; industrial production volume; and the general
business trend towards the outsourcing of services. The outlook for 2005
continues to be positive for these business drivers. Currently, the Company is
generally experiencing increased activity in its industrial services businesses.
Domestically, Access Services rental equipment on the customer job sites is at
the highest level since 2001; the estimated future value of mill services
contracts as of December 31, 2004 was $3.7 billion; and backlogs in the
manufacturing businesses have been growing. The Company believes that its record
first quarter sales and earnings per share, the improving business drivers and
the Company's target of $140 million in growth-related capital expenditures or
acquisitions in 2005 provide a solid base for achieving the Company's stated
objective of double-digit growth in diluted earnings per share from continuing
operations in 2005.

Company Wide:

o    Strong worldwide economic activity, including increased steel production,
     benefited the Company's Mill Services Segment and resulted in strong demand
     for the Company's products and services. This included international demand
     for railway track maintenance services and equipment; access equipment
     sales and rentals especially in the Middle East; cryogenics equipment;
     industrial cylinders; industrial grating products; and air-cooled heat
     exchangers.
o    An increase in the effective income tax rate relating to continuing
     operations, from 31.0% in the first quarter of 2004 to 32.3% in the first
     quarter of 2005, resulted in approximately $0.5 million in higher income
     tax expense for the first quarter of 2005. This is more fully discussed
     under Part I, Item 1, Footnote L labeled "Income Taxes."

     MILL SERVICES SEGMENT - SIGNIFICANT IMPACTS ON OPERATING INCOME FOR THE
THREE MONTHS ENDED MARCH 31, 2005 COMPARED WITH 2004:
o    Operating income in the first quarter of 2005 increased by $0.4 million as
     a result of continued strong volume, and increased pricing and new
     business, particularly in North America, Europe and Brazil, partially
     offset by increased operating costs (as noted below).
o    The benefit of positive foreign currency translation in the first quarter
     of 2005 resulted in increased operating income of $1.2 million compared
     with the first quarter of 2004.

o    Compared with the first quarter of 2004, the Segment's operating income in
     first quarter of 2005 was negatively impacted by increased fuel and
     energy-related costs of approximately $3.6 million.
o    The Segment's operating income for the first quarter of 2005 was impacted
     by increased maintenance and repair costs; higher start-up costs for new
     contracts; and increased selling, general and administrative costs
     (including increased compensation costs and Sarbanes-Oxley Section
     404-related costs). Selling, general and administrative costs increased
     $2.4 million or 16% (versus a 14% increase in revenues) for the first
     quarter of 2005 (including approximately $0.7 million related to foreign
     currency translation).

     ========================================================================================


     ACCESS SERVICES SEGMENT - SIGNIFICANT IMPACTS ON OPERATING INCOME FOR THE
THREE MONTHS ENDED MARCH 31, 2005 COMPARED WITH 2004:
o    In the first quarter of 2005, the Segment was positively affected by the
     performance of the concrete forming rental business, particularly in the
     Middle East and the U.K.
o    Lower pension expense in the first quarter of 2005 increased operating
     income by approximately $1.0 million when compared with the first quarter
     of 2004.
o    During the first quarter of 2005, the international Access Services
     business continued to grow outside the U.K., predominantly in the Middle
     East, due to certain on-going large projects. During the first quarter of
     2005, the international operations outside of the U.K. had $61.4 million in
     revenues and $5.7 million in operating income. This compares with $41.3
     million in revenues and $3.5 million in operating income for the first
     quarter of 2004.
o    In the first quarter of 2005, there was a continued strengthening in the
     U.S. non-residential construction markets that started in the latter half
     of 2004. This strengthening had a positive effect on volume (particularly
     erection and dismantling labor revenue and equipment rental) which caused
     overall margins in the U.S. to improve. Equipment rentals, particularly in
     the construction sector, provide the highest margins for this Segment.
o    Foreign currency translation in the first quarter of 2005 did not have a
     material impact on operating income compared with the first quarter of
     2004.

     GAS TECHNOLOGIES SEGMENT - SIGNIFICANT IMPACTS ON OPERATING INCOME FOR THE
THREE MONTHS ENDED MARCH 31, 2005 COMPARED WITH 2004:
o    Operating income decreased in the first quarter of 2005 compared with the
     same period of 2004, due mainly to decreased volume for propane tanks and
     valves.
o    As expected, the propane business had decreased revenues and operating
     income in the first quarter of 2005 when compared with the first quarter of
     2004. As indicated last year, there was increased demand for propane tanks
     in the first quarter of 2004 driven by customers accelerating purchases in
     anticipation of future price increases due to higher steel prices.
o    Decreased demand for certain valves negatively impacted operating income in
     the first quarter of 2005 compared with the same period of 2004. A
     strategic action plan is being implemented to improve the results of the
     valves business. This plan is further discussed in the Outlook, Trends and
     Strategies section.
o    The international businesses, in both Asia and Europe, contributed
     significantly to the increased performance of the cryogenics business
     during the first quarter of 2005 compared with the first quarter of 2004.
o    Higher volume for industrial cylinders was due to increased demand and
     selling price increases.
o    Foreign currency translation in the first of quarter 2005 did not have a
     material impact on operating income for this Segment compared with the
     first quarter of 2004.

                         PART I - FINANCIAL INFORMATION

OUTLOOK, TRENDS AND STRATEGIES
Looking to the remainder of 2005 and beyond, the following significant items,
trends and strategies are expected to affect the Company:

Company Wide:
- -------------
o    A continued focus on expanding the higher-margin industrial services
     businesses, with a particular emphasis on growing the Mill Services Segment
     through the provision of additional services to existing customers, new
     contracts in both mature and emerging markets and strategic acquisitions.
     Significant capital investments are also expected to be made to grow the
     Access Services and railway services businesses.
o    The continued growth of the Chinese steel industry could impact the Company
     in several ways. Increased steel mill production in China may provide
     additional service opportunities for the Mill Services Segment. However,
     continued increased Chinese economic activity may result in increased
     commodity costs which may adversely affect the Company's manufacturing
     businesses. The impact of this risk is currently unknown.
o    Higher fuel, energy, transportation and material costs, particularly steel,
     have been encountered during 2004 and the first quarter of 2005. Although
     certain costs (e.g., steel) are expected to moderate during the remainder
     of 2005, should these costs continue to rise, the Company's operating costs
     would increase and profitability would decline to the extent that such
     costs cannot be passed to customers.
o    The Company will continue to focus on improving Economic Value Added
     (EVA(R)).
o    A target of a record $320 million in net cash provided by operating
     activities has been established for 2005.
o    Foreign currency translation has had a favorable effect on the Company's
     sales and income during the first quarter of 2005. However, should the U.S.
     dollar strengthen, particularly in relationship to the euro or British
     pound sterling, the impact on the Company would generally be negative in
     terms of reduced sales and income.
o    Cost reductions and Six Sigma continuous process improvement initiatives
     across the Company should further enhance margins. This includes improved
     supply chain management and additional outsourcing in the manufacturing
     businesses.
o    The current trend towards rising interest rates in the U.S. should not
     significantly increase the Company's overall interest expense.
     Approximately 87% of the Company's current borrowings are at fixed interest
     rates, principally in British pounds sterling or U.S. dollars.
     Additionally, approximately 84% of the Company's borrowings are long-term
     in nature and do not mature until 2010 or later. Should the Company require
     significant additional borrowings to finance growth-related acquisitions,
     they would be at the prevailing market interest rates which may be higher
     than the Company is currently paying under its commercial paper programs.
o    On October 22, 2004, the American Jobs Creation Act (AJCA) was signed into
     law. The AJCA includes a deduction of 85% for certain international
     earnings that are repatriated, as defined in the AJCA, to the U.S. The
     Company may elect to apply this temporary provision to qualifying earnings
     repatriations during 2005. On January 13, 2005, the U.S. Treasury
     Department and the U.S. Internal Revenue Service (IRS) issued the first in
     a series of notices that will provide detailed guidance on the AJCA. On
     April 18, 2005 the IRS stated that they are working to finalize certain
     issues and release the second round of guidance. The Company is assessing
     the effects of the repatriation provision and expects to complete its
     evaluation within a reasonable period of time following the publication of
     additional guidance by the U.S. Treasury Department and IRS, as well as the
     possible action by Congress to enact technical corrections. A specific
     range of income tax effects of these repatriations has not been determined;
     however, the Company does not expect a significant impact due to the
     structure of its international operations as well as the substantial amount
     of repatriations to the U.S. in prior years.

Mill Services Segment:
- ----------------------
o    According to the International Iron and Steel Institute (IISI), global
     steel production (excluding China) for the first quarter of 2005 increased
     by 1% compared with the first quarter of 2004. Global steel demand and
     production is expected to remain strong in 2005, and bidding activity for
     new mill services contracts and add-on services is strong. There have been
     recent media reports regarding a potential decline in U.S. steel production
     to allow the steel mills to maintain pricing. A decline in U.S. production
     should not have a significant impact on this Segment since approximately
     80% of Segment revenues are earned internationally.
o    Positive growth momentum is expected to continue for the remainder of 2005.
     However, foreign currency translation is not expected to be as much a
     factor in 2005 as it was in 2004. Most of the Mill Services growth this
     year should come primarily from add-on services and investments, including
     possible bolt-on acquisitions.
o    The increased energy-related costs this Segment experienced during the
     first quarter of 2005 are expected to persist through the rest of the year;
     however, it is expected that price escalation clauses that are built into
     existing contracts will assist the Company in recovering a portion of these
     increased costs from customers.
o    The risk remains that certain Mill Services customers may be acquired or
     consolidate in the future, which could have an adverse impact on the
     Company's income and cash flows. Conversely, such consolidation may provide
     additional

     service opportunities for the Company. A merger during April 2005 of two of
     the  Company's larger customers has created the world's largest steel
     company. Currently, the effect of this merger on the Company cannot be
     estimated.

Access Services Segment:
- ------------------------
o    Both the international and U.S. Access Services businesses are expected to
     show continued improvement during 2005.
o    U.S. non-residential construction activity continued to improve in the
     first quarter of 2005 and the overall market outlook remains positive.
     Although industry sources have trimmed their forecasts for U.S.
     non-residential construction growth from 5% to 4% for the year due to the
     first quarter's severe weather conditions on the West Coast, the remainder
     of the year is forecasted to improve as previously predicted. Additionally,
     new office building and hotel starts are still expected to see double-digit
     growth for 2005.
o    Positive growth momentum is expected to continue for the remainder of 2005.
     However, foreign currency translation is not expected to be as much a
     factor in 2005 as it was in 2004.
o    The current trend towards increasing interest rates in the U.S. should help
     support equipment rental rate increases that have been instituted during
     the first quarter of 2005.

Gas Technologies Segment:
- -------------------------
o    Although cost inflation for certain commodities is expected to moderate in
     2005, continued increases in steel prices; worldwide demand for steel; and
     availability of carbon fiber used to manufacture filament-wound composite
     cylinders could have an adverse effect on future raw material costs, and
     this Segment's ability to obtain the necessary raw materials.
o    Weak market conditions for valves; manufacturing inefficiencies; new
     product start-up costs; and increased raw material costs have impacted the
     valves business during the first quarter of 2005. A comprehensive strategic
     plan has been developed and it is currently being executed to mitigate
     these conditions. They include the following: development and marketing of
     new products; focus on an expanded international customer base; outsourcing
     of certain manufacturing processes; consolidating certain manufacturing
     process; process improvements within the manufacturing operations; and
     optimization of the organizational structure of the business. If the
     conditions encountered during 2004 and the first quarter of 2005 persist
     despite execution of the strategic action plan, the valuation of this
     business could be negatively impacted.
o    Despite a decline in the first quarter of 2005, the propane business is
     expected to perform well in 2005 as a whole, as it returns to its more
     normal business cycle.

Engineered Products and Services ("all other") Category:
- --------------------------------------------------------
o    International demand for the railway track maintenance services and
     equipment business' products and services is expected to grow.
     Additionally, Six Sigma process improvements, new technologies and improved
     manufacturing efficiencies are expected to assist in improving margins of
     this business.
o    The industrial grating business is expected to sustain continued
     profitability for 2005. However, the ability to pass increased commodity
     costs (e.g., steel) to customers may diminish.
o    Although cost inflation for certain commodities is expected to moderate in
     2005, continued increases in steel prices and worldwide demand for steel
     could have an adverse effect on raw material costs and the ability to
     obtain the necessary raw materials for most businesses in this Category.
o    Consistent, profitable results are expected from the roofing granules and
     abrasives business.
o    Due to an improving natural gas market, demand for air-cooled heat
     exchangers is expected to remain strong for the balance of the 2005 and
     stable into 2006.

than the 15% increase in revenues. The lower relative increase in SG&A expenses
(10%) as compared with revenues (15%) was due to stringent cost controls,
process improvements and reorganization actions. The absolute dollar increase in
SG&A expenses was attributable to the following significant items:

INCOME TAX EXPENSE FROM CONTINUING OPERATIONS

First Quarter 2005 vs. First Quarter 2004
- -----------------------------------------
The increase in the first quarter of 2005 of $3.6 million or 42% in income tax
expense from continuing operations was due to increased earnings from continuing
operations for the reasons mentioned above and an increase in the effective
income tax rate relating to continuing operations from 31% in the first quarter
of 2004 to 32.3% in the first quarter of 2005. The increase in the effective
income tax rate was primarily a result of the expiration of three tax holidays;
one in Europe, one in the Middle East and one in Asia.

================================================================================

NET INCOME AND EARNINGS PER SHARE

First Quarter 2005 vs. First Quarter 2004
- -----------------------------------------
Net income of $23.1 million and diluted earnings per share of $0.55 in the first
quarter of 2005 exceeded the first quarter of 2004 by $6.1 million and $0.14,
respectively, due to increased income from continuing operations. This increase
primarily resulted from increased revenues, stringent cost controls, process
improvements and reorganization actions that contained selling, general and
administrative expenses growth to a 10% increase while revenue increased 15%;
partially offset by an increased effective income tax rate.


LIQUIDITY AND CAPITAL RESOURCES

OVERVIEW
The Company's principal sources of liquidity are cash from operations and
short-term borrowings under its various credit agreements, augmented
periodically by cash proceeds from asset sales. During 2004, the Company
achieved record net cash provided by operating activities of $270.5 million.
During the first three months of 2005, net cash provided by operating activities
of $48.1 million was 49% higher than in the first three months of 2004. Due to
record capital investments of $58.3 million for the first three months of 2005
and the seasonal aspect of the Company's cash flows in the first three months of
the year, the Company's net cash borrowings increased $8.7 million in the first
three months of 2005.

The Company's management reaffirms its previously stated strategic objectives
for 2005 that include generating a record $320 million in net cash provided by
operating activities, augmented by targeted asset sales. The Company's strategy
is to redeploy excess or discretionary cash in new long-term, high renewal-rate
services contracts for the Mill Services business and for growth in the Access
Services and railway track maintenance services businesses. The Company will
also pursue sensible bolt-on acquisitions to further enhance its industrial
services growth and increase Economic Value Added (EVA(R)). The Company has
targeted a minimum of $140 million of discretionary cash flow for internal
growth opportunities and acquisitions. Additionally, the Company will use funds
from targeted asset sales for acquisitions or growth initiatives. The Company
also plans to continue its long history of paying dividends to stockholders.

The Company also plans to pay down debt to the extent possible. However, as of
March 31, 2005, the Company had only approximately $71 million of debt that can
be paid prior to maturity. The balance of the debt, principally the Company's
(pound)200 million notes and its $150 million notes, cannot be paid until
maturity in 2010 and 2013, respectively.

COMMERCIAL COMMITMENTS
As of March 31, 2005, there was a decrease in the standby letters of credit and
performance bonds of approximately $91.4 million from the total $218.3 million
outstanding at December 31, 2004. This decrease was due principally to the
release in January 2005 of an $80 million surety bond and a $9 million standby
letter of credit, both related to the Company's settled Federal Excise Tax (FET)
dispute, as previously reported in the Annual Report on Form 10-K.

SOURCES AND USES OF CASH
The primary drivers of the Company's cash flow from operations are the Company's
sales and income, particularly in the services businesses. The Company's
long-term mill services contracts provide predictable cash flows for several
years into the future. (See "Certainty of Cash Flows" section for additional
information on estimated future revenues of Mill Services contracts and order
backlogs for the Company's manufacturing businesses and railway track
maintenance services business.) Additionally, returns on capital investments
made in prior years, for which no cash is currently required, are a significant
source of operating cash. Depreciation related to these investments is a
non-cash charge. The Company also continues to maintain working capital at a
manageable level based upon the requirements and seasonality of the business.

                         PART I - FINANCIAL INFORMATION


Major uses of operating cash flows and borrowed funds include payroll costs and
related benefits; pension funding payments; raw material purchases for the
manufacturing businesses; income tax payments; interest payments; insurance
premiums and payments of self-insured casualty losses; and machinery, equipment,
automobile and facility rental payments. Other primary uses of cash include
capital investments, principally in the industrial services businesses; debt
payments; and dividend payments. Cash will also be used for acquisitions as the
appropriate opportunities arise.

     RESOURCES AVAILABLE FOR CASH REQUIREMENTS - The Company has various credit
facilities and commercial paper programs available for use throughout the world.

     CREDIT RATINGS AND OUTLOOK - The following table summarizes the Company's
debt ratings at March 31, 2005:

                        LONG-TERM NOTES    U.S.-BASED COMMERCIAL PAPER   OUTLOOK

Moody's                        A3                      P-2                Stable
Fitch (a)                      A-                      F-2                Stable
- --------------------------------------------------------------------------------

(a)  The Company's (pound)200 million notes are not rated by Fitch.

The euro commercial paper market does not require commercial paper to be rated.
Accordingly, the Company's euro-based commercial paper program has not been
rated. In February 2005, Fitch reaffirmed its A- and F-2 ratings for the
Company's long-term notes and U.S. commercial paper, respectively, and its
stable outlook. S&P and Moody's reaffirmed their stable outlooks for the Company
in November 2004 and September 2004, respectively. A downgrade to the Company's
credit rating would probably increase the costs to the Company to borrow funds.
An improvement in the Company's credit rating would probably decrease the costs
to the Company to borrow funds.

CURRENT RATIO                                1.6:1         1.6:1
==============================================================================

Working capital decreased approximately 3% in the first three months of 2005 due
principally to the following factors:

o    Cash decreased $15.7 million due to the timing of cash receipts at the end
     of December 2004. In December 2004, the Company received approximately $12
     million in cash too late in the month to pay down debt. In March 2005, this
     situation did not occur.

o    Notes and accounts receivable decreased $19.5 million due principally to
     lower sales and increased cash collections at the railway track maintenance
     services and equipment business for the first quarter of 2005 compared with
     the fourth quarter of 2004, as well as the timing of cash collections in
     the propane unit of the Gas Technologies Segment. The decrease was
     partially offset by increases in the North American Access Services
     business due mainly to higher sales in the first quarter of 2005 compared
     with the fourth quarter of 2004, and the timing of collections.

o    Inventories increased $30.8 million from December 31, 2004 due to the
     following factors: increased work-in-process and raw materials inventories
     for long-lead-time orders at the railway track maintenance services and
     equipment business scheduled for delivery in the second half of 2005;
     increased finished goods for the international Access Services and gas
     technologies businesses to meet expected demand in the second and third
     quarters of 2005.

o    Notes payable and current maturities increased $21.0 million due
     principally to increased commercial paper borrowings during the first
     quarter of 2005.

o    Accrued compensation decreased $14.9 million due principally to the payment
     of 2004 accrued bonuses during the first quarter of 2005.

     CERTAINTY OF CASH FLOWS - The certainty of the Company's future cash flows
is strengthened by the long-term nature of the Company's mill services
contracts. At December 31, 2004, the Company's mill services contracts had
estimated future revenues of $3.7 billion. Of that amount, approximately 59% is
expected to be recognized by December 31, 2007. In addition, as of March 31,
2005, the Company had an order backlog of $256.7 million for its manufacturing
businesses (excluding the roofing granules and slag abrasives business) and
railway track maintenance services. This compares with $243.0 million at
December 31, 2004 and $213.9 million at March 31, 2004. The increase from
December 31, 2004 is due principally to new orders for heat exchangers in the
Engineered Products and Services ("all other") Category and increased demand for
industrial cylinders and cryogenics equipment in the Gas Technologies Segment.
The railway track maintenance services and equipment business backlog includes a
significant portion that is long-term, which will not be

realized until the second half of 2005 or later due to the long lead times
necessary to build certain equipment and the long-term nature of certain service
contracts.

The types of products and services that the Company provides are not subject to
rapid technological change. This increases the stability of related cash flows.
Additionally, each of the Company's businesses is among the top three companies
(relative to sales) in the industries the Company serves. Due to these factors,
the Company is confident in its future ability to generate positive cash flows
from operations.

The Company's cash flows from operating, investing and financing activities, as

     CASH FROM OPERATING ACTIVITIES - Net cash provided by operating activities
in the first three months of 2005 was $48.1 million, an increase of $15.8
million from the first three months of 2004. The increased cash from operations
was principally a result of the following factors:

o    Increased net income in the first quarter of 2005 compared with the first
     quarter of 2004.

o    Net receivables decreased as of March 31, 2005 compared with December 31,
     2004. This was due principally to greater collections at the railway track
     maintenance services and equipment business and the Gas Technologies
     Segment.

o    Inventories increased as of March 31, 2005 compared with December 31, 2004.
     This was to meet scheduled shipments at the railway track maintenance
     services and equipment business and anticipated shipments for the Gas
     Technologies Segment.

o    Accrued compensation decreased as of March 31, 2005 compared with December
     31, 2004. This decrease was due to incentive compensation payments and the
     timing of payment of salaries and wages at most divisions.

     CASH USED IN INVESTING ACTIVITIES - Capital investments of $58.3 million
for the first three months of 2005 were a record for the first three months of a
year. This was an increase of $11.8 million over the first three months of 2004.
Overall, approximately 50% of the first quarter 2005 investments were for
projects intended to grow future revenues. Investments were made predominantly
in the industrial services businesses with 62% in the Mill Services Segment and
24% in the Access Services Segment. Throughout the remainder of 2005, the
Company plans to continue to invest in high-return projects and bolt-on
acquisitions, principally in the industrial services businesses.

Total Debt to Total Capital                         40.6%              40.6%
============================================================================

The Company's debt as a percent of total capital as of March 31, 2005 remained
the same as December 31, 2004. Overall debt decreased slightly from December 31,
2004 due to foreign currency translation. Additionally, total equity decreased
slightly due to foreign currency translation adjustments mostly offset by
increases in additional paid-in capital from stock option exercises and
increases in retained earnings as a result of the earnings in the quarter.

DEBT COVENANTS
The Company's credit facilities and certain notes payable agreements contain
covenants requiring a minimum net worth of $475 million and a maximum debt to
capital ratio of 60%. Based on balances at March 31, 2005, the Company could
increase borrowings by approximately $746.0 million and still be within its debt
covenants. Alternatively, keeping all other factors constant, the Company's
equity could decrease by approximately $437.7 million and the Company would
still be within its covenants. The Company expects to be compliant with these
debt covenants one year from now.

CASH AND VALUE-BASED MANAGEMENT
The Company plans to continue with its strategy of selective investing for
strategic purposes for the foreseeable future. The goal of this strategy is to
improve the Company's Economic Value Added (EVA(R)) under the program that
commenced January 1, 2002. Under this program, the Company evaluates strategic
investments based upon the investment's economic profit. EVA equals after-tax
operating profits less a charge for the use of the capital employed to create
those profits (only the service cost portion of defined benefit pension expense
is included for EVA purposes). Therefore, value is created when a project or
initiative produces a return above the cost of capital. In the first three
months of 2005, seven of the Company's nine divisions improved their EVA from
the comparable 2004 period.

The Company is committed to continue paying dividends to stockholders. The
Company has increased the dividend rate for eleven consecutive years, and in
February 2005, the Company paid its 219th consecutive quarterly cash dividend.
In March 2005, the Company declared its 220th consecutive quarterly cash
dividend. The Company also plans to continue paying down debt to the extent
possible. Additionally, the Company has authorization to repurchase up to one
million of its shares through January 31, 2006.

The Company's financial position and debt capacity should enable it to meet
current and future requirements. As additional resources are needed, the Company
should be able to obtain funds readily and at competitive costs. The Company is
well-positioned and intends to continue investing strategically in high-return
projects and acquisitions, reducing debt and paying cash dividends as a means to
enhance stockholder value.

ITEM 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
- --------------------------------------------------------------------

MARKET RISK.

In the normal course of business, the Company is routinely subjected to a
variety of risks. In addition to the market risk associated with interest rate
and currency movements on outstanding debt and non-U.S. dollar-denominated
assets and liabilities, other examples of risk include collectibility of
receivables, volatility of the financial markets and their effect on defined
benefit pension plans, and global economic and political conditions.

                         PART I - FINANCIAL INFORMATION


     CYCLICAL INDUSTRY AND ECONOMIC CONDITIONS MAY ADVERSELY IMPACT THE
     COMPANY'S BUSINESSES.

The Company's businesses are vulnerable to general economic slowdowns and
cyclical conditions in the industries served. In particular,

o    The Company's mill services business may be adversely impacted by slowdowns
     in steel mill production, excess capacity, consolidation or bankruptcy of
     steel producers or a reversal or slowing of current outsourcing trends in
     the steel industry;

o    The Company's Access Services business may be adversely impacted by
     slowdowns in non-residential construction and annual industrial and
     building maintenance cycles;

o    The Company's gas technologies business may be adversely impacted by
     reduced industrial production, and lower demand for industrial gases,
     slowdowns in demand for medical cylinders, valves and consumer barbecue
     grills, or lower demand for natural gas vehicles;

o    The industrial grating business may be adversely impacted by slowdowns in
     non-residential construction and industrial production;

o    The railway track maintenance business may be adversely impacted by
     developments in the railroad industry that lead to lower capital spending
     or reduced maintenance spending; and

o    The industrial abrasives and roofing granules business may be adversely
     impacted by slower home resales or economic conditions that slow the rate
     of residential roof replacement, or by slowdowns in the industrial and
     infrastructure refurbishment industries.

     THE COMPANY'S DEFINED BENEFIT PENSION EXPENSE IS DIRECTLY AFFECTED BY THE
     EQUITY AND BOND MARKETS AND A DOWNWARD TREND IN THOSE MARKETS COULD
     ADVERSELY IMPACT THE COMPANY'S FUTURE EARNINGS. AN UPWARD TREND IN THE
     EQUITY AND BOND MARKETS COULD POSITIVELY AFFECT THE COMPANY'S FUTURE
     EARNINGS.

In addition to the economic issues that directly affect the Company's
businesses, changes in the performance of equity and bond markets, particularly
in the United Kingdom and the United States, impact actuarial assumptions used
in determining annual pension expense, pension liabilities and the valuation of
the assets in the Company's defined benefit pension plans. The downturn in
financial markets during 2000, 2001 and 2002 negatively impacted the Company's
pension expense and the accounting for pension assets and liabilities. This
resulted in an increase in pre-tax defined benefit pension expense from
continuing operations of approximately $20.8 million for calendar year 2002
compared with 2001 and $17.7 million for calendar year 2003 compared with 2002.
The upturn in certain financial markets during 2003 and certain plan design
changes (discussed below) contributed to a decrease in pre-tax defined benefit
pension expense from continuing operations of approximately $5.4 million for
2004 compared with 2003. An upward trend in capital markets would likely result
in a decrease in future unfunded obligations and pension expense. This could
also result in an increase to Stockholders' Equity and a decrease in the
Company's statutory funding requirements. If the financial markets deteriorate,
it would most likely have a negative impact on the Company's pension expense and
the accounting for pension assets and liabilities. This could result in a
decrease to Stockholders' Equity and an increase in the Company's statutory
funding requirements.

In response to the adverse market conditions, during 2002 and 2003 the Company
conducted a comprehensive global review of its pension plans in order to
formulate a plan to make its long-term pension costs more predictable and
affordable. The Company implemented design changes for most of these plans
during 2003. The principal change involved converting future pension benefits
for many of the Company's non-union employees in both the U.K. and U.S. from
defined benefit plans to defined contribution plans as of January 1, 2004. This
conversion is expected to make the Company's pension expense more predictable
and affordable and less sensitive to changes in the financial markets.

                         PART I - FINANCIAL INFORMATION


     THE COMPANY'S GLOBAL PRESENCE SUBJECTS IT TO A VARIETY OF RISKS ARISING
     FROM DOING BUSINESS INTERNATIONALLY.

The Company operates in over 40 countries, including the United States. The
Company's global footprint exposes it to a variety of risks that may adversely
impact results of operations, cash flows or financial position. These include
the following:

o    periodic economic downturns in the countries in which the Company does
     business;

o    fluctuations in currency exchange rates;

o    customs matters and changes in trade policy or tariff regulations;

o    imposition of or increases in currency exchange controls and hard currency
     shortages;

o    changes in regulatory requirements in the countries in which the Company
     does business;

o    higher tax rates and potentially adverse tax consequences including
     restrictions on repatriating earnings, adverse tax withholding requirements
     and "double taxation";

o    longer payment cycles and difficulty in collecting accounts receivable;

o    complications in complying with a variety of international laws and
     regulations;

o    political, economic and social instability, civil unrest and armed
     hostilities in the countries in which the Company does business;

o    inflation rates in the countries in which the Company does business;

o    laws in various international jurisdictions that limit the right and
     ability of subsidiaries to pay dividends and remit earnings to affiliated
     companies unless specified conditions are met; and,

o    uncertainties arising from local business practices, cultural
     considerations and international political and trade tensions.

If the Company is unable to successfully manage the risks associated with its
global business, the Company's financial condition, cash flows and results of
operations may suffer.

The Company has operations in several countries in the Middle East, including
Bahrain, Egypt, Saudi Arabia, United Arab Emirates and Qatar, which are
geographically close to Iraq and other countries with a continued high risk of
armed hostilities. During the first quarter of 2005, 2004 and 2003, these
countries contributed approximately $7.4 million, $4.7 million and $4.0 million,
respectively, to the Company's operating income. Additionally, the Company has
operations in and sales to countries that have encountered outbreaks of
communicable diseases (e.g., Acquired Immune Deficiency Syndrome (AIDS)). Should
these outbreaks worsen or spread to other countries, the Company may be
negatively impacted through reduced sales to and within these countries and
other countries impacted by such diseases.

     EXCHANGE RATE FLUCTUATIONS MAY ADVERSELY IMPACT THE COMPANY'S BUSINESS.

Fluctuations in foreign exchange rates between the U.S. dollar and the
approximately 35 other currencies in which the Company conducts business may
adversely affect the Company's operating income and income from continuing
operations in any given fiscal period. Approximately 60% and 59% of the
Company's sales and approximately 75% and 76% of the Company's operating income
from continuing operations for the three months ended March 31, 2005 and 2004,
respectively, were derived from operations outside the United States. More
specifically, during the three months ended March 31, 2005 and 2004,
approximately 21% and 23%, respectively, of the Company's revenues were derived
from operations in the U.K. Additionally, approximately 18% of the Company's
revenues were derived from operations with the euro as their functional currency
during both the three months ended March 31, 2005 and 2004. Given the structure
of the Company's revenues and expenses, an increase in the value of the U.S.
dollar relative to the foreign currencies in which the Company earns its
revenues generally has a negative impact on operating income, whereas a decrease
in the value of the U.S. dollar tends to have the opposite effect. The Company's
principal foreign currency exposures are to the British pound sterling and the
euro.
                                      -31-

                   HARSCO CORPORATION AND SUBSIDIARY COMPANIES
                         PART I - FINANCIAL INFORMATION


Compared with the corresponding period in 2004, the average values of major
currencies changed as follows in relation to the U.S. dollar during 2005,
impacting the Company's sales and income:

     o   British pound sterling         Strengthened by 3%
     o   euro                           Strengthened by 6%
     o   South African rand             Strengthened by 10%
     o   Brazilian real                 Strengthened by 9%
     o   Australian dollar              Strengthened by 2%

The Company's foreign currency exposures increase the risk of income statement,
balance sheet and cash flow volatility. If the above currencies change
materially in relation to the U.S. dollar, the Company's financial position,
results of operations, or cash flows may be materially affected.

To illustrate the effect of foreign currency exchange rate changes in certain
key markets of the Company, in the first three months of 2005, revenues would
have been approximately 2% or $15.6 million less and income from continuing
operations would have been approximately 6% or $1.3 million less if the average
exchange rates for the first three months of 2004 were utilized. A similar
comparison for the first three months of 2004 would have decreased revenues
approximately 7% or $38.6 million while income from continuing operations would
have been approximately 7% or $1.1 million less if the average exchange rates
would have remained the same as the first three months of 2003.

Currency changes result in assets and liabilities denominated in local
currencies being translated into U.S. dollars at different amounts than at the
prior period end. These currency changes resulted in decreased net assets of
$20.9 million and $3.1 million, at March 31, 2005 and 2004, respectively, when
compared with December 31, 2004 and 2003, respectively.

The Company seeks to reduce exposures to foreign currency transaction
fluctuations through the use of forward exchange contracts. At March 31, 2005,
the notional amount of these contracts was $96.1 million, and all will mature
before August 2005. The Company does not hold or issue financial instruments for
trading purposes, and it is the Company's policy to prohibit the use of
derivatives for speculative purposes.

Although the Company engages in foreign currency forward exchange contracts and
other hedging strategies to mitigate foreign exchange risk, hedging strategies
may not be successful or may fail to offset the risk.

In addition, competitive conditions in the Company's manufacturing businesses
may limit the Company's ability to increase product prices in the face of
adverse currency movements. Sales of products manufactured in the United States
for the domestic and export markets may be affected by the value of the U.S.
dollar relative to other currencies. Any long-term strengthening of the U.S.
dollar could depress demand for these products and reduce sales and may cause
translation gains or losses due to the revaluation of foreign
currency-denominated accounts payable, accounts receivable and other asset and
liability accounts. Conversely, any long-term weakening of the U.S. dollar could
improve demand for these products and increase sales and may cause translation
gains or losses due to the revaluation of accounts payable, accounts receivable
and other asset and liability accounts.

     NEGATIVE ECONOMIC CONDITIONS MAY ADVERSELY IMPACT THE ABILITY OF THE
     COMPANY'S CUSTOMERS TO MEET THEIR OBLIGATIONS TO THE COMPANY ON A TIMELY
     BASIS AND IMPACT THE VALUATION OF THE COMPANY'S ASSETS.

If a downturn in the economy occurs, it may adversely impact the ability of the
Company's customers to meet their obligations to the Company on a timely basis
and could result in bankruptcy filings by them. If customers are unable to meet
their obligations on a timely basis, it could adversely impact the realizability
of receivables, the valuation of inventories and the valuation of long-lived
assets across the Company's businesses, as well as negatively impact the
forecasts used in performing the Company's goodwill impairment testing under
SFAS No. 142, "Goodwill and Other Intangible Assets." If management determines
that goodwill or assets are impaired or that inventories or receivables cannot
be realized at recorded amounts, the Company will be required to record a
write-down in the period of determination, which will reduce net income for that
period. Additionally, the risk remains that certain Mill Services customers may
file for bankruptcy protection, be acquired or consolidate in the future, which
could have an adverse impact on the Company's income and cash flows. Conversely,
such consolidation may provide additional service opportunities for the Company.

                         PART I - FINANCIAL INFORMATION


     A NEGATIVE OUTCOME ON PERSONAL INJURY CLAIMS AGAINST THE COMPANY MAY
     ADVERSELY IMPACT RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

The Company has been named as one of many defendants (approximately 90 or more
in most cases) in legal actions alleging personal injury from exposure to
airborne asbestos. In their suits, the plaintiffs have named as defendants many
manufacturers, distributors and repairers of numerous types of equipment or
products that may involve asbestos. Most of these complaints contain a standard
claim for damages of $20 million or more against the named defendants. The
Company has not paid any amounts in settlement of these cases, with the
exception of two settlements totaling less than $10,000 paid by the insurance
carrier prior to 1998. However, if the Company was found to be liable in any of
these actions and the liability was to exceed the Company's insurance coverage,
results of operations, cash flows and financial condition could be adversely
affected. For more information concerning this litigation, see Note I,
"Commitments and Contingencies," in Part 1, Item 1, Financial Statements.

     THE COMPANY MAY LOSE CUSTOMERS OR BE REQUIRED TO REDUCE PRICES AS A RESULT
     OF COMPETITION.

The industries in which the Company operates are highly competitive.

o    The Company's Mill Services business is sustained mainly through contract
     renewals. Historically, the Company's contract renewal rate has averaged
     around 95%. If the Company is unable to renew its contracts at its
     historical levels, revenue may decline.

o    The Company's Access Services business rents and sells equipment and
     provides erection and dismantling services to principally the
     non-residential construction and industrial plant maintenance markets.
     Contracts are awarded based upon the Company's engineering capabilities,
     product availability and the ability to competitively price its rentals and
     services. During economic cycle downturns in their home markets, certain
     international competitors have exported significant quantities of rental
     equipment to the markets the Company serves, particularly the U.S. This has
     caused an oversupply of certain equipment and a consequential reduction in
     product and rental pricing in the markets receiving the excess equipment.
     If the Company is unable to consistently provide high-quality products and
     services at competitive prices, it may lose customers or operating margins
     may decline due to reduced selling prices.

o    The Company's manufacturing businesses compete with companies that
     manufacture similar products both internationally and domestically. Certain
     international competitors export their products into the United States and
     sell them at lower prices due to lower labor costs and government subsidies
     for exports. Such practices may limit the prices the Company can charge for
     its products and services. Additionally, unfavorable foreign exchange rates
     can adversely impact the Company's ability to match the prices charged by
     international competitors. If the Company is unable to match the prices
     charged by international competitors, it may lose customers.

The Company's strategy to overcome this competition includes Six Sigma
continuous process improvement and cost reduction programs, international
customer focus and the diversification, streamlining and consolidation of
operations.

     INCREASES IN ENERGY PRICES COULD INCREASE THE COMPANY'S OPERATING COSTS AND
     REDUCE ITS PROFITABILITY.

Worldwide political and economic conditions, among other factors, may result in
an increase in the volatility of energy costs, both on a macro basis and for the
Company specifically. In the first three months of 2005 and 2004, energy costs
have approximated 3.9% and 3.8% of the Company's revenue, respectively. To the
extent that such costs cannot be passed to customers in the future, operating
income and results of operations may be adversely affected.

     INCREASES OR DECREASES IN PURCHASE PRICES OR AVAILABILITY OF STEEL OR OTHER
     MATERIALS AND COMMODITIES MAY AFFECT THE COMPANY'S PROFITABILITY.

The profitability of the Company's manufactured products are affected by
changing purchase prices of steel and other materials and commodities. Beginning
in 2004, the price paid for steel and certain other commodities increased
significantly compared with prior years. If steel or other material costs
associated with the Company's manufactured products increase and the costs
cannot be passed on to the Company's customers, then operating income will be
adversely affected. Additionally, decreased availability of steel or other
materials, such as carbon fiber used to manufacture filament-wound composite
cylinders, could affect the Company's ability to produce manufactured products
in a timely manner. If the Company cannot obtain the necessary raw materials for
its manufactured products, then revenues, operating income and cash flows will
be adversely affected.

                         PART I - FINANCIAL INFORMATION


     THE COMPANY IS SUBJECT TO VARIOUS ENVIRONMENTAL LAWS AND THE SUCCESS OF
     EXISTING OR FUTURE ENVIRONMENTAL CLAIMS AGAINST IT COULD ADVERSELY IMPACT
     THE COMPANY'S RESULTS OF OPERATIONS AND CASH FLOWS.

The Company's operations are subject to various federal, state, local and
foreign laws, regulations and ordinances relating to the protection of health,
safety and the environment, including those governing discharges to air and
water, handling and disposal practices for solid and hazardous wastes, the
remediation of contaminated sites and the maintenance of a safe work place.
These laws impose penalties, fines and other sanctions for non-compliance and
liability for response costs, property damages and personal injury resulting
from past and current spills, disposals or other releases of, or exposure to,
hazardous materials. The Company could incur substantial costs as a result of
non-compliance with or liability for remediation or other costs or damages under
these laws. The Company may be subject to more stringent environmental laws in
the future, and compliance with more stringent environmental requirements may
require the Company to make material expenditures or subject it to liabilities
that the Company currently does not anticipate.

The Company is currently involved in a number of environmental remediation
investigations and clean-ups and, along with other companies, has been
identified as a "potentially responsible party" for certain waste disposal
sites under the federal "Superfund" law. At several sites, the Company is
currently conducting environmental remediation, and it is probable that the
Company will agree to make payments toward funding certain other of these
remediation activities. It also is possible that some of these matters will be
decided unfavorably to the Company and that other sites requiring remediation
will be identified. Each of these matters is subject to various uncertainties
and financial exposure is dependent upon such factors as the continuing
evolution of environmental laws and regulatory requirements, the availability
and application of technology, the allocation of cost among potentially
responsible parties, the years of remedial activity required and the remediation
methods selected. The Company has evaluated its potential liability and the
Consolidated Balance Sheets at both March 31, 2005 and December 31, 2004
included an accrual of $2.7 million, for environmental matters. The amounts
charged against pre-tax earnings related to environmental matters totaled $0.3
million and $0.4 million for the three months ended March 31, 2005 and 2004,
respectively. The liability for future remediation costs is evaluated on a
quarterly basis. Actual costs to be incurred at identified sites in future
periods may be greater than the estimates, given inherent uncertainties in
evaluating environmental exposures.

     RESTRICTIONS IMPOSED BY THE COMPANY'S CREDIT FACILITIES AND OUTSTANDING
     NOTES MAY LIMIT THE COMPANY'S ABILITY TO OBTAIN ADDITIONAL FINANCING OR TO
     PURSUE BUSINESS OPPORTUNITIES.

The Company's credit facilities and certain notes payable agreements contain a
covenant requiring a maximum debt to capital ratio of 60%. In addition, certain
notes payable agreements also contain a covenant requiring a minimum net worth
of $475 million. These covenants limit the amount of debt the Company may incur,
which could limit its ability to obtain additional financing or to pursue
business opportunities. In addition, the Company's ability to comply with these
ratios may be affected by events beyond its control. A breach of any of these
covenants or the inability to comply with the required financial ratios could
result in a default under these credit facilities. In the event of any default
under these credit facilities, the lenders under those facilities could elect to
declare all borrowings outstanding, together with accrued and unpaid interest
and other fees, to be due and payable, which would cause an event of default
under the notes. This could, in turn, trigger an event of default under the
cross-default provisions of the Company's other outstanding indebtedness. At
March 31, 2005, the Company was in compliance with these covenants and $378.8
million in indebtedness containing these covenants was outstanding.

     HIGHER THAN EXPECTED CLAIMS UNDER INSURANCE POLICIES, UNDER WHICH THE
     COMPANY RETAINS A PORTION OF RISK, COULD ADVERSELY IMPACT RESULTS OF
     OPERATIONS AND CASH FLOWS.

The Company retains a significant portion of the risk for property, workers'
compensation, automobile, general and product liability losses. Reserves have
been recorded which reflect the undiscounted estimated liabilities for ultimate
losses including claims incurred but not reported. Inherent in these estimates
are assumptions that are based on the Company's history of claims and losses, a
detailed analysis of existing claims with respect to potential value, and
current legal and legislative trends. At March 31, 2005 and December 31, 2004,
the Company had recorded liabilities of $78.0 million and $77.4 million,
respectively, related to both asserted and unasserted insurance claims. If
actual claims are higher than those projected by management, an increase to the
Company's insurance reserves may be required and would be recorded as a charge
to income in the period the need for the change was determined. Conversely, if
actual claims are lower than those projected by management, a decrease to the
Company's insurance reserves may be required and would be recorded as a
reduction to expense in the period the need for the change was determined.

     THE SEASONALITY OF THE COMPANY'S BUSINESS MAY CAUSE ITS QUARTERLY RESULTS
     TO FLUCTUATE.

The Company has historically generated the majority of its cash flows in the
third and fourth quarters (periods ending September 30 and December 31). This is
a direct result of normally higher sales and income during the latter part of
the year, as the Company's business tends to follow seasonal patterns. If the
Company is unable to successfully manage the cash flow and other effects of
seasonality on the business, its results of operations may suffer.

     THE COMPANY'S CASH FLOWS AND EARNINGS ARE SUBJECT TO CHANGES IN INTEREST
     RATES.

The Company's total debt as of March 31, 2005 was $623.0 million. Of this
amount, approximately 13% had variable rates of interest and 87% had fixed rates
of interest. The weighted average interest rate of total debt was approximately
6.3%. At current debt levels, a one-percentage increase/decrease in variable
interest rates would increase/decrease interest expense by approximately $0.8
million per year. Should the Company require significant additional borrowings
to finance growth-related acquisitions, they would be at the prevailing market
interest rates which may be higher than the Company is currently paying under
its commercial paper programs.

The future financial impact on the Company associated with the above risks
cannot be estimated.


ITEM 4.   CONTROLS AND PROCEDURES
- ---------------------------------

The Company's management, including the Chief Executive Officer and Chief
Financial Officer, has conducted an evaluation of the effectiveness of
disclosure controls and procedures as of March 31, 2005. Based on that
evaluation, the Chief Executive Officer and Chief Financial Officer concluded
that the disclosure controls and procedures are effective. There have been no
significant changes in internal controls, or in factors that could significantly
affect internal controls, during the first quarter of 2005 or subsequent to the
date of their evaluation.
