For release:      IMMEDIATELY


                  AIRGAS REPORTS SECOND QUARTER EPS OF $0.26

RADNOR, PA - October 29, 2003 -- Airgas, Inc., (NYSE: ARG) today reported
earnings for its second quarter ended September 30, 2003.  Net earnings
for the quarter were $19.1 million, or $0.26 per diluted share, compared
to $19.2 million, or $0.27 per diluted share, in the same period a year
ago.  Second quarter results include insurance-related losses of $2.8
million, or $0.02 per diluted share, for previously announced incidents
at two of the Company's facilities.

Second quarter sales increased 2% to $460 million, while total same-store
sales were essentially flat compared to the same quarter a year ago,
reflecting continued weakness in manufacturing and other industrial
segments.  Same-store sales in the Distribution segment were down 1%,
driven by a 2% decline in hardgoods.  Same-store sales for the Gas
Operations segment increased 4%, attributed to sales from the Hopewell,
Virginia CO2 plant, which began operations in January 2003.

Net earnings for the six months ended September 30, 2003 were $0.51 per
diluted share compared to prior year results of $0.46 per diluted share.
The six months ended September 30, 2002 included charges of $2.9 million
($2.2 million after tax), or $0.03 per diluted share, related to a
special charge for the integration of the Air Products acquisition ($2.7
million) and a net divestiture loss.

"I am pleased with our operational and financial performance in the
second quarter," said Airgas Chairman and Chief Executive Officer Peter
McCausland.  "Airgas associates are managing well in a tough environment.
We will continue to manage our costs conservatively until it becomes
clearer that the industrial economy is on the mend."

Free Cash Flow for the six months ended September 30, 2003 was $33
million compared to $29 million in the prior year, driving a $22 million
reduction in adjusted debt.  The definition of free cash flow and a
reconciliation to the attached Consolidated Statement of Cash Flows, as
well as the definition of adjusted debt and a reconciliation to the
balance sheet are attached.


McCausland continued, "Daily sales rates improved sequentially throughout
the quarter, with September posting the highest level we've seen since
December.  October trends are running slightly behind September.  We are
cautiously optimistic, although it is important to remember that the
industrial economy still has a long road to recovery.  We have adjusted
the range for our full year earnings per share guidance to $1.03 to
$1.10, specifically reflecting the insurance related losses of $0.02 per
share in the second quarter."

30, 2003, beginning at 11:00 a.m. Eastern Time.  Access the

Notes:

(a)  Special charges of $2.7 million ($1.7 million after tax) for the six
     months ended September 30, 2002 consist of a restructuring charge
     related to the integration of the business acquired from Air Products
     in the fourth quarter of fiscal 2002 and costs related to the
     consolidation of the Company's procurement functions. The special
     charges include facility exit costs associated with the closure of
     certain Airgas facilities and severance for approximately 130 employees.

(b)  The Company participates in a securitization agreement with two
     commercial banks to sell up to $175 million of qualified trade
     receivables.  Net proceeds from the securitization were used to
     reduce borrowings under the Company's revolving credit facilities.
     The amount of outstanding receivables under the agreement was
     $152.7 million and $158.9 million at September 30, 2003 and March 31,
     2003, respectively.

(c)  Since October 1999, the Company has leased certain real estate and
     equipment from a grantor trust (the "Trust") established by a
     commercial bank under a sale-leaseback arrangement.  The Trust was
     not consolidated for financial reporting purposes.  Effective July 1,
     2003, the Company has elected to early adopt Financial
     Accounting Standards Board Interpretation No. 46, which requires
     the consolidation of the Trust.  The consolidation of the Trust
     resulted in the Company recording assets of $29 million and debt
     of $42 million, while eliminating a deferred gain of $13 million
     that was previously carried on the balance sheet as a long-term
     liability.  Consolidation of the Trust was a non-cash transaction.

  meaningful measure of the change in the Company's obligation to repay debt
  by adjusting for non-cash items and funds received (or repaid) under the
  trade receivables securitization program.
