This prospectus is part of an automatic shelf registration statement that we filed with the Securities and Exchange Commission (the “Commission”) as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”), utilizing a “shelf” registration process.

This prospectus provides you with a general description of the securities we may offer. Each time we sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus. You should read both this prospectus and any prospectus supplement together with additional information described under the heading “Where You Can Find More Information” below.

We intend to use the net proceeds from the sale of the debt securities offered by this prospectus for general corporate purposes. These may include repayment of other indebtedness, capital expenditures, possible acquisitions and other purposes as may be specified in the applicable prospectus supplement.

The ratio of earnings to fixed charges has been computed by dividing “earnings available for fixed charges” by “fixed charges.” For purposes of computing this ratio, “earnings available for fixed charges” principally consists of (i) earnings before income taxes and minority interest, plus (ii) “fixed charges.” “Fixed charges” principally consists of interest expense and the portion of rental expense that is representative of the interest factor.

The following description of the terms of the debt securities sets forth certain general terms and provisions of the debt securities to which any prospectus supplement may relate. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which these general provisions may apply to those debt securities will be described in the prospectus supplement relating to those debt securities. Accordingly, for a description of the terms of a particular issue of debt securities, reference must be made to both the prospectus supplement relating thereto and to the following description.

The debt securities may be issued from time to time under the indenture in an unlimited aggregate principal amount and an unlimited number of series. The indenture will be qualified under the Trust Indenture Act of 1939.

The debt securities are unsecured and will have the same rank as all other unsecured and non-subordinated debt of the Company.

The following summaries of material provisions of the notes and the indentures are subject to, and qualified in their entirety by reference to, all the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplements related to the debt securities that we sell under this prospectus, as well as the complete indentures that contain the terms of the debt securities.

The prospectus supplement relating to the series of debt securities which it offers describes to the extent applicable:

If specified in the prospectus supplement, certain of our subsidiaries (our “Subsidiary Guarantors”) will guarantee the debt securities of a series.

The debt securities will be issued in registered form, without interest coupons. There will be no service charge for any registration of transfer or exchange of the debt securities. However, payment of any transfer tax or similar governmental charge payable for that registration may be required.

Debt securities of any series will be exchangeable for other debt securities of the same series, the same total principal amount and the same terms but in different authorized denominations in accordance with the applicable indenture. Holders may present debt securities for registration of transfer at the office of the security registrar or any transfer agent we designate. The security registrar or transfer agent will effect the transfer or exchange if its requirements and the requirements of the applicable indenture are met.

The trustee will be appointed as security registrar for the debt securities. If a prospectus supplement refers to any transfer agents we initially designate, we may at any time rescind that designation or approve a change in the location through which any transfer agent acts. We are required to maintain an office or agency for transfers and exchanges in each place of payment. We may at any time designate additional transfer agents for any series of debt securities.

In the case of any redemption, we will not be required to register the transfer or exchange of:

Unless we inform you otherwise in a prospectus supplement, payments on the debt securities will be made in U.S. dollars at the office of the trustee and any paying agent. At our option, however, payments may be made by wire transfer for global debt securities or by check mailed to the address of the person entitled to the payment as it appears in the security register. Unless we inform you otherwise in a prospectus supplement, interest payments may be made to the person in whose name the debt security is registered at the close of business on the record date for the interest payment.

Unless we inform you otherwise in a prospectus supplement, the trustee under the applicable indenture will be designated as the paying agent for payments on debt securities issued under that indenture. We may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts.

If the principal of, or any premium or interest on, debt securities of a series is payable on a day that is not a business day, the payment will be made on the following business day. For these purposes, unless we inform you otherwise in a prospectus supplement, a “business day” means each day on which commercial banks and foreign exchange markets settle payments in the place or places where the principal of (and premium, if any) and interest, if any, on the Securities of that series are payable, or place of publication. Unless otherwise specified, “business day” shall exclude any day on which commercial banks and foreign exchange markets do not settle payments in London.

Subject to the requirements of any applicable abandoned property laws, the trustee and paying agent will pay to us upon written request any money held by them for payments on the debt securities that remains unclaimed for two years after the date upon which that payment has become due. After payment to us, holders entitled to the money must look to us for payment. In that case, all liability of the trustee or paying agent with respect to that money will cease.

The debt securities of a series may be issued in the form of one or more global debt securities that would be deposited with a depositary or its nominee identified in the prospectus supplement. Global debt securities may be issued in either temporary or permanent form. We will describe in the prospectus supplement the terms of any depositary arrangement and the rights and limitations of owners of beneficial interests in any global debt security.

At the request of the Company, the indenture will cease to be in effect as to the debt securities of any series (except for certain obligations to register the transfer or exchange of such debt securities and related coupons, if any, and hold moneys for payment of such debt securities and coupons in trust) when either (a) all such debt securities and coupons have been delivered to the trustee for cancellation or (b) all such debt securities and coupons have become due and payable or will become due and payable at their stated maturity within one year, or are to be called for redemption within one year, and the Company has deposited with the trustee, in trust money, in the currency, currencies or currency unit or units in which such debt securities are payable, in an amount sufficient to pay all the principal of, and premium and interest, if any, on, such debt securities on the dates such payments are due in accordance with the terms of such debt securities.

The Company may defease any series of debt securities and, at its option, either (a) be discharged after 90 days from any and all obligations in respect of such series of debt securities (except for certain obligations to register the transfer of or exchange debt securities and related coupons, replace stolen, lost or mutilated debt securities and coupons, maintain paying agencies and hold moneys for payment in trust) or (b) eliminate the requirement to comply with certain restrictive covenants of the indenture in respect of such series. In order to exercise either defeasance option, the Company must deposit with the trustee in trust, money, or, in the case of debt securities and coupons denominated in U.S. dollars, U.S. treasuries or, in the case of debt securities and coupons denominated in a foreign currency, foreign government securities, which through the payment of interest thereon and principal thereof in accordance with their terms will provide money, in an amount sufficient to pay in the currency, currencies or currency unit or units in which such debt securities are payable all the principal (including any mandatory sinking fund payments) of, and interest on, such series on the dates such payments are due in accordance with the terms of such series. Among the conditions to the Company exercising any such option, the Company is required to deliver to the trustee an opinion of counsel to the effect that the deposit and related defeasance would not cause the holders of such series to recognize income, gain or loss for United States Federal income tax purposes and that the holders of such series will be subject to United States Federal income tax in the same amounts, in the same manner and at the same times as would have been the case if such option had not been exercised.

The following are events of default under each indenture with respect to any series of debt securities that we may issue:

No event of default with respect to a single series of indebtedness issued under the indenture (and any supplemental indentures) necessarily constitutes an event of default with respect to any other series of indebtedness issued thereunder.

The indenture provides that the trustee will, within 90 days after the occurrence of a default with respect to the debt securities of any series, give to the holders of the debt securities of such series notice of all uncured and unwaived defaults known to it; provided that, except in the case of default in the payment of principal of, or premium or interest, if any, on, or a sinking fund installment, if any, with respect to any of the debt securities of such series, the trustee will be protected in withholding such notice if it in good faith determines that the withholding of such notice is in the interest of the holders of the debt securities of such series. The term “default” for the purpose of this provision only means the happening of any of the events of default specified above, except that any grace period or notice requirement is eliminated.

The indenture contains provisions entitling the trustee, subject to the duty of the trustee during an event of default to act with the required standard of care, to be indemnified by the holders of the debt securities before proceeding to exercise any right or power under the indenture at the request of holders of the debt securities.

The indenture provides that the holders of a majority in principal amount of the outstanding debt securities of any series may in certain circumstances direct the time, method and place of conducting proceedings for remedies available to the trustee or exercising any trust or power conferred on the trustee in respect of such series.

The indenture includes a covenant that obligates us to file annually with the trustee an officers’ certificate stating whether any default exists and specifying any default that exists.

In certain cases, the holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all debt securities of such series waive any past default or event of default with respect to the debt securities of such series or compliance with certain provisions of the indenture, except, among other things, a default not theretofore cured in payment of the principal of, or premium or interest, if any, on, any of the debt securities of such series. The holders of a majority in principal amount of a series of outstanding debt securities also have certain rights to rescind any declaration of acceleration with respect to such series after all events of default with respect to such series not arising from such declaration shall have been cured.

The indenture allows us and the trustee, without the consent of any holders of debt securities, to enter into supplemental indentures for the purposes, among other things, of:

The indenture allows us and the trustee, with the consent of the holders of not less than a majority in principal amount of the outstanding debt securities of all affected series (acting as one class), to execute supplemental indentures adding any provisions to or changing or eliminating any of the provisions of the indenture or modifying the rights of the holders of the debt securities of such series. But no supplemental indenture may, without the consent of the holders of all the outstanding debt securities affected thereby, among other things:

The indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York, except to the extent that the Trust Indenture Act of 1939 is applicable.

The prospectus supplement will provide information concerning the trustee.

We may sell the debt securities in any of three ways: (i) through underwriters, (ii) through dealers or agents or (iii) directly to a limited number of institutional purchasers or to a single purchaser. The applicable prospectus supplement, will set forth the terms of the offering of the debt securities of such series, including the name or names of any underwriters, the purchase price and the proceeds we receive from such sale, any underwriting discounts and other items constituting underwriters’ compensation, any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers and other specific terms of the particular offering. Only the agents or underwriters named in a prospectus supplement are agents or underwriters in connection with the securities being offered by that prospectus supplement.

If we use underwriters in the sale, the debt securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The debt securities may be either offered to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Unless otherwise set forth in the prospectus supplement, the obligations of the underwriters to purchase debt securities will be subject to certain conditions precedent and the underwriters will be obligated to purchase all the debt securities of a series if any are purchased. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

We may sell debt securities directly or through agents designated by us from time to time. Any agent involved in the offer or sale of the debt securities in respect of which this prospectus is delivered will be named, and any commissions payable by us to such agent will be set forth, in the prospectus supplement. Unless otherwise indicated in the prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment.

We may authorize agents or underwriters to solicit offers by certain types of institutions to purchase debt securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. Such contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth the commissions payable for solicitation of such contracts.

Agents and underwriters may be entitled under agreements entered into with us and/or our subsidiaries to indemnification against certain civil liabilities, including liabilities under the Securities Act of 1933, and/or to contribution with respect to payments which the agents or underwriters may be required to make in respect thereof. Agents and underwriters may be customers of, engage in transactions with, or perform services for, the Company in the ordinary course of business.

Each series of debt securities will be a new issue of securities with no established trading market. Any underwriters to whom we sell debt securities for public offering and sale may make a market in such debt securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given as to the liquidity of the trading market for any debt securities.

During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, whereby selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if such offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, these activities may be discontinued at any time.

Unless otherwise indicated in your prospectus supplement or confirmation of sale, the purchase price of the securities will be required to be paid in immediately available funds in New York City.

Cravath, Swaine & Moore LLP will issue an opinion concerning the validity of the offered debt securities for Airgas, Inc. Any underwriter, dealer or agent will be advised about other legal issues relating to any offering by its own legal counsel.

The consolidated financial statements and schedule of Airgas, Inc. and subsidiaries as of March 31, 2009 and 2008, and for each of the years in the three-year period ended March 31, 2009, and management’s assessment of the effectiveness of internal control over financial reporting as of March 31, 2009 have been incorporated by reference herein and in the registration statement in reliance upon the report of KPMG LLP, independent registered public accounting firm, incorporated by reference herein, and upon the authority of said firm as experts in accounting and auditing.

The report refers to the adoption of Financial Accounting Standards Board Interpretation No. 48, “Accounting for Uncertainty in Income Taxes,” effective April 1, 2007.

The following statement sets forth the estimated amounts of expenses (subject to future contingencies), other than underwriting discounts, to be borne by the Company in connection with the offering described in this registration statement:

Section 145 of the Delaware General Corporation Law (“DGCL”) permits Airgas, and the other registrants incorporated in Delaware, to indemnify any of their respective directors or officers against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement, incurred in defense of any action (other than an action by or in the rights) arising by reason of the fact that he is or was an officer or director of the registrant if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of such registrant and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. Section 145 also permits the registrant to indemnify any such officer or director against expenses incurred in an action by or in the right of the registrant if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the registrant, except in respect of any matter as to which such person is adjudged to be liable to the registrant, in which case court approval must be sought for indemnification. This statute requires indemnification of such officers and directors against expenses to the extent they may be successful in defending any such action. This statute provides that it is not exclusive of other indemnification that may be granted by the registrant’s by-laws, a vote of stockholders or disinterested directors, agreement or otherwise. The statute permits purchase of liability insurance by the registrant on behalf of officers and directors, and the registrants have purchased such insurance.

Article VII of Airgas, Inc.’s bylaws requires indemnification to the fullest extent permitted by, and in the manner permissible under, the laws of the State of Delaware to any person made, or threatened to be made, a party to an action or proceeding, whether criminal, civil, administrative or investigative, by reason of the fact that he, his testator or intestate is or was a director or officer of Airgas, Inc. or any predecessor of Airgas, Inc., or served any other enterprise as a director or officer at the request of Airgas, Inc. or any predecessor of Airgas, Inc. The indemnification provided for in Article VII is expressly not exclusive of any other rights to which any director or officer may be entitled apart from the provisions of this Article.

The bylaws of the following subsidiaries of the Company generally provide for similar indemnification terms as those provided in the Company’s bylaws: Airgas Carbonic, Inc., Airgas-East, Inc., Airgas-Great Lakes, Inc., Airgas Investments, Inc., Airgas Merchant Holdings, Inc., Airgas-Mid America, Inc., Airgas-Mid South, Inc., Airgas-Nor Pac, Inc., Airgas-North Central, Inc., Airgas-Northern California & Nevada, Inc.,

Section 102(b)(7) of the DGCL provides that a corporation may eliminate or limit the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director; provided that such provisions shall not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL regarding the unlawful payment of dividends or stock redemptions or repurchases or (iv) for any transaction from which the director derived an improper personal benefit. No such provision shall eliminate or limit the liability of a director for any act or omission occurring prior to the date when such provision becomes effective.

Article 10 of Airgas, Inc.’s Certificate of Incorporation eliminates the liability of directors to the extent permitted by Section 102(b)(7) of the DGCL.

The certificate of incorporation for each of the following subsidiaries generally provides for similar terms regarding the limitation of liability as those provided in the Company’s Certificate of Incorporation: Airgas Carbonic, Inc., Airgas-East Inc., Airgas-Great Lakes, Inc., Airgas Investments, Inc., Airgas Merchant Holdings, Inc., Airgas-Mid America, Inc., Airgas-Mid South, Inc., Airgas-Nor Pac, Inc., Airgas-North Central, Inc., Airgas-Northern California & Nevada, Inc., Airgas-Refrigerants, Inc., Airgas Safety, Inc., Airgas-South, Inc., Airgas-Southwest, Inc., Airgas Specialty Products, Inc., Medical Gas Management, Inc., Nitrous Oxide Corp. and Oilind Safety, Inc.

The foregoing statements are subject to the detailed provisions of Section 145 and 102(b)(7) of the DGCL and the bylaws and certificate of incorporation of each registrant, as applicable.

Section 18-108 of the Delaware Limited Liability Company Act provides that a limited liability company may, and shall have the power to, indemnify and hold harmless any member or manager or other person from and against any and all claims and demands whatsoever.

The limited liability company operating agreement of Airgas Data, LLC provides that it shall indemnify any person who was or is a party defendant or is threatened to be made a party defendant to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that such a person is a member, manager or officer of the company or is or was serving at the request of the company, against expenses if the manager determines that said person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the company, and, with respect to any criminal action or proceeding, said person had no reasonable cause to believe the conduct was unlawful.

The limited liability company agreement of Airgas Merchant Gases, LLC provides that it shall indemnify and hold harmless the officers, managers and members from and against any and all claims and demands whatsoever; provided that (a) such claims or demands arise in connection with the company and its business and (b) the act or failure to act giving rise to the claim for indemnification is not determined by a court to have constituted willful misconduct, bad faith or fraud. Such indemnification shall be made for any action taken or any failure to take action without regard to whether the company would have the power to indemnify such person under any other provision of law or whether the indemnified liability arises from any action by or in the right of the company itself.

The limited liability company agreement of Airgas Retail Services, LLC provides that it shall indemnify and hold harmless the officers, the manager and the members from and against any and all claims and demands whatsoever (including reasonable legal fees and expenses incurred in defending any such claims or demands), provided that (a) such claims or demands arise in connection with the company and its business, and (b) the act or failure to act giving rise to the claim for indemnification is not determined by a court to have constituted willful misconduct, bad faith or fraud. Such indemnification shall be made for any action

The limited liability company agreement of WorldWide Welding, LLC provides that it shall indemnify and hold harmless the officers, managers and members from and against any and all claims and demands whatsoever; provided that (a) such claims or demands arise in connection with the company and its business and (b) the act or failure to act giving rise to the claim for indemnification is not determined by a court to have constituted wilful misconduct, bad faith or fraud. Such indemnification shall be made for any action taken or any failure to take action without regard to whether the company would have the power to indemnify such person under any other provision of law or whether the indemnified liability arises from any action by or in the right of the company itself.

Sections 204(a) and 317 of the California General Corporation Law authorize a corporation to indemnify its directors, officers, employees and other agents in terms sufficiently broad to permit indemnification (including reimbursement for expenses) under certain circumstances for liabilities arising under the Securities Act.

Neither the certificate of incorporation nor the bylaws of Airgas West, Inc. include provision for indemnification.

Section 2.02-1 of the Texas Business Corporation Act authorizes a corporation to indemnify a director against reasonable expenses incurred by him in connection with a proceeding in which he is a named defendant or respondent because he is or was a director if he has been wholly successful, on the merits or otherwise, in the defense of the proceeding, if such person shall have acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the corporation’s best interests. If a court of competent jurisdiction determines that the director is fairly and reasonably entitled to indemnification in view of all the relevant circumstances, whether or not he acted in good faith or in a manner he reasonably believed to be in or not opposed to the corporation’s best interests, the court may order the indemnification that the court determines is proper and equitable; but if the person is found liable to the corporation or liable on the basis that personal benefit was improperly received by the person, the indemnification shall be limited to reasonable expenses actually incurred by the person in connection with the proceeding.

Under the above-referenced section of the Texas Business Corporation Act, a provision for a corporation to indemnify or to advance expenses to a director who was, or is threatened to be made, a named defendant or respondent in a proceeding, whether contained in the articles of incorporation, the bylaws, a resolution of shareholder or directors, an agreement, or otherwise, is valid to the extent it is consistent with this article as limited by the articles of incorporation, if such a limitation exists.

Section 7-109-101/110 of the Colorado Business Corporation Act provides that a corporation may indemnify a person made a party to a proceeding for reasonable expenses incurred in connection with the proceeding, because the person is or was a director against liability incurred in the proceeding if the person’s conduct was in good faith and the person reasonably believed, in the case of conduct in an official capacity with the corporation, that such conduct was in the corporation’s best interests, and in all other cases that such conduct was at least not opposed to the corporation’s best interests and in the case of any criminal proceeding, the person had no reasonable cause to believe the person’s conduct was unlawful. No indemnification shall be made in connection with a proceeding by or in the right of the corporation in which the director was adjudged liable to the corporation, in connection with any proceeding charging that the director derived an improper personal benefit or if the director was adjudged liable on the basis that the director derived an improper personal benefit.

Section 7-108-402 of the Colorado Business Corporation Act provides that a corporation, if so provided in the articles of incorporation, shall eliminate or limit the personal liability of a director to the corporation or to its shareholders for monetary damages for breach of fiduciary duty as a director, except that any such provision shall not eliminate or limit the liability of a director to the corporation or to its shareholders for any breach of the director’s duty of loyalty to the corporation or to its shareholders, acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, acts specified in Section 7-108-403, or any transaction from which the director directly or indirectly derived an improper personal benefit. No such provision shall eliminate or limit the liability of a director to the corporation or to its shareholders for monetary damages for any act or omission occurring before the date when such provision becomes effective.

No indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the court in which such action or suit was brought shall determine that such person, despite adjudication of liability but in view of all the circumstances of the case, is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.
