                   AIRGAS, INC. COMMENTS ON SECOND QUARTER 
                              EARNINGS ESTIMATES

RADNOR, PA, OCTOBER 7, 1997 - Airgas, Inc. (NYSE: ARG) said today that it will
report significantly higher after-tax cash flow per share for the second
quarter as a result of non-recurring gains on the sale of a non-core business
and a partial recovery of refrigerant losses, but that after-tax cash flow per
share from ongoing operations will be slightly below analysts' expectations
principally because of flat August sales.  The company said that the UPS
strike had a direct adverse effect on Airgas' shipments to customers and
distribution expense and other indirect effects, including slowdowns in our
customers' business.

Peter McCausland, Airgas' Chairman and Chief Executive Officer, said, "Our
Distribution Group achieved sales growth of 4% for the period April through
July, but August sales were flat.  September rebounded to a sales growth rate
of 5%, which tends to confirm our view on the UPS strike, but we did not
recoup the lost August sales.  As a result, we expect after-tax cash flow per
share from ongoing operations will be approximately 10% above the same period
a year ago and earnings per share from ongoing operations will be slightly
below the $.17 per share reported for last year."

"While our August sales performance was a disappointment, we hope to sustain
and even accelerate the September sales growth rate for the balance of the
year.  However, if the sales rebound does not continue, we must view more
cautiously the outlook for the balance of the year and will take steps to
achieve further cost reductions."

Airgas said it expects to report results for its second quarter on     
October 23, 1997.

The Airgas Board of Directors has approved the repurchase of up to an
additional 2,000,000 shares of common stock from time to time to offset share
issuances for stock options, the Employee Stock Purchase Plan, and
acquisitions.  Together with previously granted authority, this increases the
total repurchase program to a potential 2,646,000 shares.
