                           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.


                           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.



<PAGE> 7


                         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
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.

beneficial ownership of the Company's Common Stock as of February 1, 1998, and

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The Delaware General Corporation Law permits the indemnification by a
Delaware corporation of its directors, officers, employees, and other agents
against expenses (including attorneys' fees), judgments, fines, and amounts
paid in settlement in connection with specified actions, suits or proceedings,
whether civil, criminal, administrative, or investigative (other than
derivative actions which are by or in the right of the corporation) if they
acted in good faith and in a manner they reasonably believed to be in or not
opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe their
conduct was illegal.  A similar standard of care is applicable in the case of
derivative actions, except the indemnification only extends to expenses
(including attorneys' fees) incurred in connection with defense or settlement
of such an action and requires court approval before there can be any
indemnification where the person seeking indemnification has been found liable
to the corporation.

     The Company's certificate of incorporation provides that each person who
was or is made a party to, or is involved in, any action, suit or proceeding
by reason of the fact that he or she is or was a director or officer of the
Company (or was serving at the request of the Company as a director, officer,
employee or agent for another entity) while serving in such capacity will be
indemnified and held harmless by the Company to the full extent authorized or
permitted by Delaware law.  The certificate also provides that the Company may
purchase and maintain insurance and may also create a trust fund, grant a
security interest and/or use other means (including establishing letters of
credit, surety bonds and other similar arrangements) and may enter into
contracts providing for indemnification, to ensure full payment of
indemnifiable amounts.  The Company has entered into such indemnification
agreements with its directors and executive officers.

ITEM 17.  UNDERTAKINGS.

I.   Rule 415 Offering.  The undersigned registrant hereby undertakes:

     1.   To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement: 

          (i)  To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

          (ii) To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent post-
effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the
registration statement.  Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any
deviation from the low or high end of the estimated maximum offering range may
be reflected in the form of prospectus filed with the Commission pursuant to
Rule 424(b) if, in the aggregate, the changes in volume and price represent no
more than a 20% change in the maximum aggregate offering price set forth in
the "Calculation of Registration Fee" table in the effective registration
statement.

          (iii)     To include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement;

                    Provided, however, that paragraphs (i) and (ii) above do
not apply if the registration statement is on Form S-3, Form S-8 or Form F-3
and the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed by the registrant
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934
that are incorporated by reference in this registration statement.

     2.   That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered pursuant to
this registration statement, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

     3.   To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination
of the offering.

<PAGE> 12

 II.     Filings Incorporating Subsequent Exchange Act Documents by Reference.

     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in this
registration statement shall be deemed to be a new registration statement
relating to the securities offered pursuant to this registration statement,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

III. Acceleration of Effectiveness - Indemnification Undertaking.

          Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the provisions described under Item 15
above, or otherwise, the registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable.  In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer
or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication
of such issue.<PAGE>

     Re:  Airgas, Inc.

Dear Sir or Madam:

     We have acted as counsel to Airgas, Inc. (the "Company"), a Delaware
corporation, in connection with the preparation and filing of a registration
statement on Form S-3, which was filed with the Securities and Exchange
Commission on the date hereof (the "Registration Statement").  Capitalized
terms not otherwise defined herein shall have the meanings ascribed to them in
the Registration Statement.

     The Registration Statement covers up to 1,630,311 shares of the Company's
Common Stock, par value $.01 per share (the "Shares"), issued or issuable to
the Selling Stockholders.  Of the total number of Shares covered by the
Registration Statement, 1,244,512 shares were issued by the Company on October
1, 1997 pursuant to the Agreement and Plan of Reorganization dated as of
October 1, 1997 by and among IGP Acquisition Corp., a Delaware corporation and
wholly-owned subsidiary of the Company; the Company; Industrial Gas Products &
Supply, Inc., a Colorado corporation; and J. F. Dammann, Ruth C. Dammann,
J. F. Dammann, III, and John H. Dammann(the "Merger Agreement") and the
balance of up to 385,799 Shares may be issued to the Selling Stockholders
pursuant to the Registration Rights and Stock Adjustment Agreement (the
"Registration Rights Agreement").

     We have examined the Registration Statement, including the exhibits
thereto, the Company's Amended and Restated Certificate of Incorporation, the
Company's By-Laws, as amended, the minutes of actions taken by the Board of
Directors of the Company and such other instruments as we deemed necessary for
the opinions rendered herein.  In the foregoing examination, we have assumed
the genuineness of all signatures, the authenticity of all documents submitted
to us as originals and the authenticity of all documents submitted to us as
copies of originals.

     Based upon the foregoing, we are of the opinion that:

     1.   The 1,244,512 Shares issued under the terms of the Merger Agreement
are validly issued, fully paid and non-assessable.

     2.   The 385,799 Shares that may be issued three years after October 1,
1997 under the terms of the Registration Rights Agreement, when issued in
accordance with the terms of the Registration Rights Agreement, will be
validly issued, fully paid and non-assessable.





<PAGE> 16

     We hereby consent to the filing of this opinion as Exhibit 5 to the
Registration Statement.  We also consent to the reference to this firm under
the heading "Legal Matters" in the Prospectus constituting a part of the
Registration Statement. In giving this consent, we do not hereby admit that we
come within the category of persons whose consent is required under Section 7
of the Securities Act of 1933, as amended, or the rules and regulations
thereunder.


                              Sincerely,

                              McCausland, Keen & Buckman
