                 AIRGAS, INC. ANNOUNCES RECOVERY OF $20 MILLION
                    FROM DEFENDANTS IN REFRIGERANT LITIGATION

     RADNOR, Pennsylvania, July 28, l997 -- Airgas, Inc. (NYSE-ARG) today
announced it has reached a comprehensive settlement with all of the defendants
in the litigation brought by Airgas under federal and state RICO statutes in
federal court in Georgia seeking recovery of losses Airgas incurred in certain
refrigerant gas transactions late last year.  Under the terms of the
settlement, the defendants have agreed to pay Airgas approximately $20 million
to compensate Airgas for most of the loss it recognized with a pre-tax charge
in the fourth quarter of its fiscal year ended March 31, 1997.  The settlement,
which requires court approval in bankruptcy proceedings for two of the
defendants, will result in a suspension of the trial scheduled to begin on
August 4, 1997.  Airgas said it is pressing forward with its insurers to
recover the balance of its losses and the related extra expenses.

     "We are very pleased to have achieved this substantial recovery only seven
months after announcing we had been victimized and five months after commencing
litigation," said Peter McCausland, Chairman and Chief Executive Officer of
Airgas.  "This recovery reflects the tireless efforts of the Airgas team and
our legal counsel to recover the entire amount we are owed.  We hope we can
quickly settle with our insurers on the balance of our loss so that we can put
this matter completely behind us as soon as possible."

     Airgas, Inc. is the largest distributor of industrial, medical and
specialty gases and related equipment in North America.  Its distributor
network includes approximately 640 locations in 41 states, Canada and Mexico.
