                           THE COMPANY
                                 
     The Company classifies its operations into three business segments:
Distribution, Direct Industrial and Manufacturing.  The Company believes that
it is the largest independent distributor of industrial, medical and specialty
gases and related equipment in North America. Through its Direct Industrial
segment, the Company distributes safety, industrial and environmental
supplies, and industrial tools, MRO (Maintenance, Repair and Operations)
products and welding and safety equipment.  The Company's manufacturing
operations include the production of carbon products, calcium carbide, nitrous
oxide and carbon dioxide.  The Company's principal business strategy is to
continue to expand its distribution network through internal growth and growth
through distributor acquisitions and the selective acquisition of businesses
that enhance its Direct Industrial strategy.

                        RECENT DEVELOPMENTS

     During the fourth quarter ended March 31, 1998, the Company recorded a
one-time special charge of $19.5 million ($12.4 million after-tax) related to
its "Repositioning Airgas for Growth" initiative and the divestiture of
several non-core businesses.  The special charge consisted of severance and
exit costs for the closure of duplicate facilities, a non-cash charge for the
write down of property, plant and equipment and goodwill impaired as a result
of the restructuring, and the divestiture of several non-core businesses,
offset by a one-time net gain related to an acquisition break-up fee.

     Repositioning costs of $5.7 million ($3.4 million after-tax) for
relocating employees and other personnel expenses, exiting certain product
lines, and computer conversions were also incurred in the quarter and were
charged against earnings.  In conformance with generally accepted accounting
principles, these costs and expenses were not included in the special charge.

     The fourth quarter special charges and the additional direct
repositioning costs resulted in a reported net loss in the fourth quarter of
$5.2 million, or $.07 per share, and after-tax cash flow of $37.3 million, or
$.52 per share.

                           THE OFFERING

     On October 1, 1997, the Company acquired Industrial Gas Products &
Supply, Inc. ("IGP") and, as a result, the former shareholders of IGP received
1,244,512 shares of the Company's Common Stock.  The Selling Stockholders may
also receive up to 385,799 additional shares (the "Additional Shares") three
years after October 1, 1997, if the fair market value of the Company's Common
Stock on such date is less than $13.10, subject to adjustment under certain
circumstances.  The number of Additional Shares to be issued would be based
upon the number of Shares held by the Selling Stockholders on the third
anniversary date and the difference between $13.10 (subject to adjustment
under certain circumstances) and the fair market value on October 1, 2000.

     The Selling Stockholders have been provided with certain registration
rights pursuant to a registration rights and stock adjustment agreement.  The
registration statement of which this Prospectus is a part has been filed by
the Company in satisfaction of the Company's obligations to register the
Shares for sale by the Selling Stockholders pursuant to the Selling
Stockholders' registration rights.


                         USE OF PROCEEDS

     The Company will receive no proceeds from any sales of the Shares by the
Selling Stockholders. 


     The Company will pay all fees and expenses incurred by the Company in
connection with registering the Shares for sale under the Securities Act.


                       PLAN OF DISTRIBUTION

     The Shares registered for sale hereunder may be sold from time to time by
the Selling Stockholders, or by pledgees, donees, transferees or other
successors in interest.  Any such sales may be in one or more transactions to
be executed on the New York Stock Exchange, on any other exchange on
which the Common Stock may be traded or in the over-the-counter market at
prices prevailing at the times of such sales or in private sales at prices
related to the prevailing market prices or at negotiated prices.  The sales
may involve (a) a block transaction in which the broker or dealer so engaged
will attempt to sell the Shares as agent but may position and resell a portion
of the block as principal to facilitate the transaction; (b) purchases by a
broker or dealer as principal and resale by such broker or dealer for its
account pursuant to this Prospectus; (c) an exchange distribution in
accordance with the rules of such exchange; and (d) ordinary brokerage
transactions and transactions in which the broker solicits purchases.  

     The Selling Stockholders will be subject to applicable provisions of the
Securities Exchange Act of 1934 and the rules and regulations thereunder.  In
effecting sales, brokers or dealers engaged by the Selling Stockholders may
arrange for other brokers or dealers to participate. Brokers or dealers may
receive compensation in the form of underwriting discounts, concessions or
commissions (which compensation may be in excess of customary commissions).
The Selling Stockholders and any brokers or dealers that participate in the
distribution of the Shares may be deemed to be underwriters and any
commissions received by them and any profit on the resale of the Shares
positioned by them might be deemed to be underwriting discounts and
commissions under the Securities Act of 1933.  In the event that the Selling 

 5

Stockholders engage an underwriter in connection with the sale of Shares, the
Selling Stockholders have agreed to file with the Commission, as an exhibit to
the registration statement of which this Prospectus is a part, an underwriting
agreement, if any, entered into with such underwriter and to disclose any
compensation arrangement between the Selling Stockholders and the underwriter
in a supplement to this Prospectus or, if required, in a post-effective
amendment to the registration statement of which this Prospectus is a part. 
Any shares covered by this Prospectus which qualify for sale pursuant
to Rule 144 promulgated under the Securities Act of 1933 may be sold under
Rule 144 rather than pursuant to this Prospectus.
