       AIRGAS ANNOUNCES AUTHORIZATION TO REPURCHASE SEVEN MILLION SHARES

RADNOR, PA - March 11, 1999 - Airgas, Inc. (NYSE: ARG) today announced that
its Board of Directors authorized the repurchase of up to seven million
shares, or approximately 10%, of the company's outstanding common stock.  The
shares may be purchased in the open market or in privately negotiated
transactions depending on market conditions and other factors.  Airgas will
complete the repurchase of approximately 450,000 shares that remain under a
previously announced two-million-share repurchase plan before buying under the
new program.  Airgas has approximately 71 million shares of common stock
outstanding.

"The share repurchase program is an expression of our confidence in the future
of Airgas," commented Peter McCausland, Airgas' Chairman and CEO.  "We believe
that Airgas' stock is undervalued and presents an excellent investment
opportunity.  Our businesses generate strong, sustainable cash flows, which
have been overshadowed by Repositioning expenses and significant long-term
investments made over the past couple of years.  With our infrastructure build-
out and Repositioning nearing completion, acquisition activity at lower than
historic levels and projected lower future capital expenditures, we believe
this is an opportune time to repurchase our shares.  Nonetheless, the current
economic environment presents some near-term uncertainties, and we intend to
gear share repurchases to the pace of our acquisition program, planned working
capital improvements, the completion of previously announced divestitures and
operating results going forward.  We are building Airgas for the long term and
we intend to balance our share repurchases with the need to maintain access to
capital at a reasonable cost in order to fund our future growth."
