EXHIBIT 13

Management's Discussion and Analysis

Sales and Earnings

Sales were $500,985,000 in 1996, a 3% increase over the prior year's
$487,668,000. Sales in 1995 were 6% higher than sales in 1994 of $459,607,000.
Net income increased 22% in 1996 to $23,061,000 from $18,912,000 in 1995, which
was 23% higher than 1994's income of $15,329,000. Earnings per share of common
stock was $4.74 in 1996, $3.32 in 1995, and $2.58 in 1994. Earnings per share
have benefitted from share repurchases that have reduced average shares
outstanding 14% in 1996 and 4% in 1995.

The 1996 sales increase occurred primarily in U.S. commercial markets, while
sales to U.S. government agencies once again decreased significantly.
International sales improved only slightly, principally in Europe. As in 1995,
commercial sales in the U.S. continue to be adversely affected by the impasse on
issuance of new Superfund and government site cleanup contracts. The 1995 sales
increase occurred primarily in the international markets, particularly in
Europe. Overall, 1995 sales by U.S. operations were about the same as 1994, with
increases in domestic commercial sales being offset by lower sales to the U.S.
government.

U.S. commercial sales increased almost 6% in 1996, as compared to increases of
4% in 1995 and 9% in 1994. Sales of instruments and specialty chemicals
sustained in 1996 the growth patterns shown in 1995 and 1994. Conversely, lower
government funding and changing customer preferences continue to reduce sales of
respiratory protection equipment. A large part of the comparative sales increase
in 1994 resulted from the acquisition of Hazco Services, Inc. in the last half
of 1993.

Sales by international operations, stated in U.S. dollars, increased 1-1/2% in
1996, 16-1/2% in 1995, and 4-1/2% in 1994. The European economic environment was
stagnant in 1996 after notable market growth occurred in Europe in 1995
following stabilization of economic conditions in 1994. Other international
markets were about the same in 1996 after significant market growth in 1995 and
1994 occurred in Australia, Brazil and Chile.

Shipments of products to U.S. government agencies in 1996 were $30,893,000, an
11% decrease from 1995 sales of $34,815,000, which were 25% lower than 1994
shipments of $46,478,000. These sales represent 6% of consolidated sales in 1996
as compared to 7% in 1995 and 10% in 1994. New contracts received in 1996 were
$14,834,000 as compared to $29,002,000 in 1995 and $27,832,000 in 1994. The 1996
year-end backlog was $14,371,000, a 53% decrease from the 1995 year-end backlog
of $30,430,000.

The 1996 gross profit rate was 38.7%, as compared to 39.1% in 1995 and 37.6% in
1994. The profitability of operations reflects cost reductions from improved
manufacturing and distribution processes, along with careful expense management.
Additionally, commercial sales carry greater margins than military sales; thus
the change of sales mix has also contributed to higher profit margins. The 1996
and 1995 gross profit have also been favorably affected by LIFO credits of
$10,361,000 and $5,455,000, respectively, arising from liquidations of LIFO
inventory values calculated at lower costs incurred in prior years, and
adversely affected by charges of $5,200,000 and $2,140,000, respectively,
arising from inventory valuation adjustments. The completion and partial
termination of some government contracts and ongoing process reengineering has
resulted in significant reductions in U.S. manufacturing inventories.

Depreciation, selling and administrative expenses were 31% of sales in 1996, 32%
in 1995, and 31% in 1994. The after-tax effects of foreign currency exchange
losses charged to income in 1996 reduced net income $667,000 or $.14 per share,
as compared to $1,279,000 or $.23 per share in 1995, and $3,840,000 or $.65 per
share in 1994. The more significant losses resulted from the currency valuation
changes that occurred in Brazil and Mexico in each of the three years. The
effective income tax rates were 37.1% in 1996, 42.9% in 1995, and 40.6% in 1994.

Restructuring

During 1996 the company initiated restructuring efforts to reduce its cost
structure and improve its competitive position. These actions included employee
reductions, writedowns for impaired assets, and facilities consolidation, the
most significant of which is the planned closing of the Esmond, Rhode Island
plant primarily because of the low level of personal protective equipment
business with the U.S. government. Commercial product activities currently
performed at Esmond will be relocated to other safety product manufacturing
facilities.

The more significant costs included in the $7,786,000 charge to 1996 operations
are:

(1) separation pay of $4,581,000, of which $1,303,000 was paid in 1996. The
number of employees affected is approximately 270, of which about 110 had
terminated as of December 31, 1996. These terminations were primarily in
manufacturing operations and administration.

(2) building, machinery and tooling writedowns, the primary non-cash provisions,
of $2,961,000.

     

                                      10



The accrued termination benefits will be paid during 1997. Other significant
cash outlays over the next one to two years will be incurred for relocation of
people and equipment, site preparation, start-up costs, and new equipment, and
will be charged to income primarily when incurred. The major portion of these
costs are expected to occur in 1997. Anticipated future benefits will result
from the reduced costs associated with a downsized production capacity better
aligned with product demands.

Restructuring charges of $730,000 in 1995 related primarily to workforce
reductions at international locations, whereas charges of $3,086,000 in 1994
were primarily applicable to completing the disposition of assets of the former
Catalyst Research Division, which was closed in 1992.


Financial Condition and Funds Flow

Cash and cash equivalents decreased $6,854,000 during 1996. Accounts receivable
increased $10,785,000 to $101,740,000 at December 31, 1996. Trade receivables
expressed in number of days sales outstanding were 71 days, as compared to 65
days in 1995. Inventories decreased $6,581,000 to $77,040,000 at December 31,
1996, resulting from completion of government contracts, improvements in
manufacturing and distribution processes, and currency exchange rate changes.
Inventory measured against sales turned 6.5 times in 1996 and 5.8 times in 1995.
The working capital ratio was 2.5 and 3.2 to 1 at years-end 1996 and 1995,
respectively.

Short-term debts of international affiliates are payable in local currencies,
which is in keeping with the company's policy of minimizing foreign currency
exposures by offsetting foreign currency assets with foreign currency debt. The
average interest rate on these loans, which include the effects of borrowing in
certain countries where local inflation has resulted in high interest rates, was
approximately 13%.

Long-term debt and the current portion thereof decreased $1,458,000 to
$15,871,000, a conservative 6% of total capital. Total capital is defined as
long-term debt plus current portion of long-term debt and shareholders' equity.

Capital expenditures were $21,583,000 in 1996, as compared to $19,136,000 in
1995. The company has continued its program of plant and equipment modernization
to increase efficiency of existing manufacturing and distribution facilities.
For the most part, capital expenditures were financed internally through
retained earnings. In the past five years, approximately $107 million has been
spent on new plants, equipment and distribution facilities.

Dividends paid on the common stock during 1996 (the 79th consecutive year of a
dividend payment) were $1.10 per share, up from the $1.06 per share paid during
1995 and $.94 per share paid
   

                                      11



    
in 1994. Cash dividends have been paid at a conservative percentage of income,
which has permitted the company to finance its growth almost exclusively through
retained earnings. During 1996, the company repurchased 601,962 common shares
for $28,853,000. As of December 31, 1996, an additional 500,000 shares may be
repurchased under current authorizations.

Credit available at year-end with banks was the U.S. dollar equivalent of
$17,157,000. The company's financial position remains strong and should provide
adequate capital resources for growth.

Cumulative Currency Translation Adjustment

The year-end position of the U.S. dollar relative to foreign currencies resulted
in translation losses of $747,000 being charged to the cumulative translation
adjustments shareholders equity account in 1996, as compared to gains of
$2,876,000 in 1995 and $5,050,000 in 1994. Significant losses occurred in
Germany and Japan, offset to some degree by gains in Australia and Britain, in
1996, while significant gains occurred in Germany in 1995 and in Australia,
Britain, and Germany in 1994.

The company's stock transfer agent is Norwest Bank Minnesota, N.A., 161 North
Concord Exchange, P. O. Box 738, South St. Paul, MN 55075-0738.

Common Stock

At December 31, 1996, there were 4,611,125 shares of common stock outstanding.
There were approximately 410 identifiable common stockholders as of November 15,
1996, a recent date for dividends. The common stock last-sale price and up-to-

fairly reflect the transactions of the company in a consistent manner on the
accrual basis of accounting.

Company personnel are trained and given responsibilities to ensure adequate
internal accounting controls at a cost commensurate with the risks involved.
Internal accounting controls, monitored by an internal audit staff, provide
reasonable assurances that transactions are executed in accordance with proper
authorization and that adequate accountability for the company's assets is
maintained.

The Board of Directors, through its Audit Committee, is responsible for
assuring that management fulfills its responsibilities in the preparation of the

Report of Independent Accountants
To the Shareholders and Board of Directors of Mine Safety Appliances Company

In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of income, of earnings retained in the business, and of
cash flows present fairly, in all material respects, the financial position of
Mine Safety Appliances Company and its subsidiaries at December 31, 1996 and
1995, and the results of their operations and their cash flows for each of the
three years in the period ended December 31, 1996, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

Notes to Consolidated Financial Statements

Note 1--Basis of Presentation

Significant accounting policies are stated in italics at the applicable notes to
consolidated financial statements.

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

All significant majority-owned companies are included in the consolidated
financial statements. Investments in which the company has an equity interest of
20% to 50% are carried at equity in net assets. Intercompany transactions are
eliminated in consolidation.

Sales under contracts are recorded at fixed or estimated contract sales prices
as deliveries are made. Contracts requiring performance over several periods are
accounted for by the percentage-of-completion method of accounting. Profits
expected to be realized are based on estimates of total sales and costs at
completion. These estimates are periodically reviewed and revised during the
contract performance period. Adjustments to profits are recorded in the period
in which estimates are revised; losses are recognized in full as they are
identified.
 
Property is stated at cost. Depreciation is based on estimated useful lives
using accelerated and straight-line methods. Maintenance and repairs are charged
to expense. Renewals and betterments which substantially extend the useful life
of property are capitalized. Profits or losses resulting from dispositions are
included in income.

The financial statements of companies for which the United States dollar is
determined to be the functional currency are translated using current and
historic exchange rates; adjustments related thereto are included in income for
the current period. The financial statements of all other companies are
translated from their functional currency into United States dollars using
current exchange rates; the resultant translation adjustments are not included
in income but are accumulated in a separate equity account. Transaction gains
and losses are recognized in income for the current period.

Cash and cash equivalents in the Consolidated Statement of Cash Flows includes
temporary investments that are readily marketable and have minimal risk as to
change in value. Certain securities have maturities in excess of ninety days;
but, as part of the company's cash management program, maturities are scheduled
based on expected cash needs for the ensuing twelve months.

Earnings per share is computed based upon the weighted average number of common
shares outstanding during each year. Shares held by the stock compensation trust
that have not been committed to be released are not considered as outstanding
shares. The computation recognizes dividends paid on preferred stock but does
not include a negligible dilutive effect of stock options.

Note 2--Other Income



Other income is summarized as follows:

Note 3--Inventories

The U.S. inventories are valued on the last-in, first-out (LIFO) cost method.
Other inventories are valued at the lower of cost, using average or current
standard costs which approximate actual costs on a first-in, first-out (FIFO)
basis, or market, determined by replacement cost or net realizable value.

Significant reductions of domestic inventories during 1996, 1995 and 1994 caused
liquidations of LIFO inventory values calculated at lower costs incurred in
prior years. The effect of these liquidations has been to reduce cost of sales
by $10,361,000 in 1996, $5,455,000 in 1995 and $6,923,000 in 1994, and to
increase net income by $6,217,000 ($1.28 per share), $3,200,000 ($.56 per share)
and $4,189,000 ($.71 per share), respectively.

Inventories are summarized as follows:

Transfers between geographic areas are stated at established intercompany
selling prices. Operating profit is total revenues less operating expenses.
Interest income and expense, equity in unconsolidated affiliates, facilities
consolidation and restructuring charges, contract costs recovery, and income
taxes have not been included in computing operating profit. Corporate assets not
included in identifiable assets are principally cash and investments.

Sales by U.S. operations to U.S. government agencies were $30,893,000 in 1996,
$34,815,000 in 1995, and $46,478,000 in 1994.

Note 6--Restructuring

Restructuring charges of $7,786,000 in 1996, most of which relate to the planned
closing of the company's Esmond, Rhode Island safety products manufacturing
facility, include $4,581,000 for separation pay to approximately 270 employees
and $2,961,000 for impaired assets. Charges of $730,000 in 1995 related
primarily to workforce reductions at international locations, and 1994 charges
of $3,086,000 applied primarily to disposition of assets of the Catalyst
Research Division, which was closed in 1992.

Note 7--Research and Development Expense

Research and development costs, charged against income as incurred, were
$19,122,000 in 1996, $20,366,000 in 1995, and $20,575,000 in 1994.

Note 8--Income Taxes

Income taxes are accounted for in accordance with Statement of Financial
Accounting Standards No. 109. Deferred tax balances are stated at tax rates
expected to be in effect when taxes are actually paid or recovered. No provision
is made for undistributed earnings of international companies since little or no
tax would result under applicable existing statutes or because management
intends that these earnings be permanently reinvested for working capital and
capital expenditure requirements.

The U.S. and non-U.S. components of income before income taxes, and provisions
for income taxes are summarized as follows:

Second cumulative preferred voting stock--none has been issued.

As to the 4-1/2% cumulative preferred stock, 71,373 shares have been issued
(none during the three years ended December 31, 1996), while the amounts held in
treasury at each year end are 1996 - 49,313 shares, $1,595; 1995 - 47,935

The company has established the Mine Safety Appliances Company Stock
Compensation Trust, the purpose of which is to fund certain benefit plans,
including employee stock options and awards. In June 1996, the company sold
600,000 treasury shares, at market value, to the Trust, in exchange for a
$28,200,000 promissory note, 8% interest, payable to the company.

On February 10, 1997, the company adopted a Shareholder Rights Plan which
includes distribution of rights as a dividend at the rate of one right for each
share of the company's common stock owned on February 21, 1997. Each right will
entitle the holder to buy a fraction of a share of a participating preferred
stock for $225 in the event certain persons or groups acquire 15% or more of the
company's outstanding common stock. Each right will entitle its holder to
purchase common stock having a value twice the exercise price. These rights will
expire on February 21, 2007.

Note 10--Leases

The company leases warehouses, sales offices, manufacturing facilities and
equipment under agreements expiring at various dates through 2001, with renewal
options existing for varying periods. Rental expense for these leases charged to
income was $6,956,000 in 1996, $6,970,000 in 1995, and $6,452,000 in 1994.
Future minimum rental commitments under noncancelable leases are not
significant.

Note 12--Short-Term Debt

Short-term bank lines of credit amounted to $19,131,000 of which $17,157,000 was
unused at December 31, 1996. Generally, these short-term lines of credit are
renewable annually and there are no significant commitment fees or compensating
balance requirements. Short-term borrowings with banks, which exclude the
current portion of long-term debt, were $5,491,000 and $3,362,000 at December
31, 1996 and 1995, respectively. The average month-end balance of total short-
term borrowings during 1996 was $2,912,000 while the maximum month-end balance
of $5,491,000 occurred at December 31, 1996. The average interest rate during
1996 was approximately 13% based upon total short-term interest expense divided
by the average month-end balance outstanding, and 18% at year-end. This average
interest rate is affected by borrowings in certain countries where local
inflation has resulted in relatively high interest rates.

Note 13--Retirement Plans

Substantially all employees are covered by non-contributory pension plans.
Various U.S. employees also participate in a contributory retirement savings
plan wherein employees may contribute from 1% to 10% of their compensation to a
trust fund, to which the company contributes an amount equal to 50% of the
employees' contributions not in excess of 8%. The company's expense for these
plans was $2,798,000 in 1996, $3,069,000 in 1995, and $4,647,000 in 1994.

The non-contributory pension plans are accounted for in accordance with
Statement of Financial Accounting Standards No. 87 which requires use of the
projected unit credit cost method to determine the projected benefit obligation
and plan cost. The principal U.S. plan is funded in compliance with the Employee
Retirement Income Security Act (ERISA). It is the general policy to fund current
costs for the international plans except in Germany, where it is common practice
and permissible under tax laws to accrue book reserves. Non-contributory plan
benefits are generally based on years of service and employees' compensation
during the last years of employment. Benefits are paid from funds previously
provided to trustees or are paid by the company and charged to the book
reserves.

Information pertaining to the non-contributory defined benefit plans is provided
in the following tables.

Annual rates of increase in the costs of covered health care benefits assumed
for 1996 were 7%, decreasing gradually to 4% for the year 1999 and thereafter.
The health care cost trend rate assumption has a significant effect on the
amounts reported; a one-percentage-point increase in each year would increase
the accumulated postretirement benefit obligation by $1,157,000 and increase the
current service and interest costs for the year by $147,000.

Note 15--Stock Plans

The company's Management Share Incentive Plan permits the granting of restricted
stock awards and stock options to eligible key employees through December 1997.
The 1990 Non-Employee Directors' Stock Option Plan provides for annual grants of
stock options to eligible directors. As of December 31, 1996, there were 257,090
shares and 37,800 shares, respectively, reserved for future grants pursuant to
these Plans.

Stock options are generally granted at market value option prices and expire
after ten years (limited instances of option prices in excess of market value
and expiration after five years). Restricted stock awards are granted (17,050
shares in 1996) to employees without payment to the company in consideration of
services to be performed in ensuing five-year periods. The company applies
Accounting Principles Board Opinion No. 25 and related Interpretations in
accounting for the Plans. Accordingly, no compensation cost has been recognized
for the stock option grants. Compensation cost for the restricted stock awards
is measured by the market value of the shares when awarded and is amortized by
charges to operations over the period that the employee provides the service.
The expense charged to operations was $350,000 in 1996, $238,000 in 1995, and
$413,000 in 1994. The company's net income and earnings per share would not be
significantly affected if compensation cost for these Plans was determined based
on fair value at grant dates consistent with the method provided in Statement of
Financial Accounting Standards No. 123.

A summary of the two stock option plans follows:
