Disclaimers (AGA)

Notice and Disclaimer of Liability Concerning the Use of NFPA Standards


NFPA® codes, standards, recommended practices, and guides (“NFPA Standards”), of which the document contained herein is one, and AGA’s Z223.1 are each developed through a consensus standards development process approved by the American National Standards Institute. These processes bring together volunteers representing varied viewpoints and interests to achieve consensus on fire and other safety issues. While the AGA and the NFPA each administer their own standards development process and establish rules to promote fairness in the development of consensus, neither one independently tests, evaluates, or verifies the accuracy of any information or the soundness of any judgments contained in their codes and standards.

The AGA and NFPA each disclaim liability for any personal injury, property, or other damages of any nature whatsoever, whether special, indirect, consequential or compensatory, directly or indirectly resulting from the publication, use of, or reliance on this document. The AGA and the NFPA also make no guaranty or warranty as to the accuracy or completeness of any information published herein. In issuing and making this document available, neither the AGA nor the NFPA are undertaking to render professional or other services for or on behalf of any person or entity. Nor are the AGA or the NFPA undertaking to perform any duty owed by any person or entity to someone else. Anyone using this document should rely on his or her own independent judgment or, as appropriate, seek the advice of a competent professional in determining the exercise of reasonable care in any given circumstances.

Neither the AGA nor the NFPA have power, nor do either of them undertake, to police or enforce compliance with the contents of this document. Nor do the AGA or the NFPA list, certify, test, or inspect products, designs, or installations for compliance with this document. Any certification or other statement of compliance with the requirements of this document shall not be attributable to the AGA or the NFPA and is solely the responsibility of the certifier or maker of the statement.

Users of NFPA® codes, standards, recommended practices, and guides (“NFPA Standards”) should be aware that these documents may be superseded at any time by the issuance of a new edition, may be amended with the issuance of Tentative Interim Amendments (TIAs), or corrected by Errata. It is intended that through regular revisions and amendments that participants in the NFPA standards development process consider the then-current and available information on incidents, materials, technologies, innovations and methods as these develop over time and that NFPA Standards reflect this consideration. Therefore, any previous edition of this document no longer represents the current NFPA Standard on the subject matter addressed. NFPA encourages the use of the most current edition of any NFPA Standard (as it may be amended by TIA(s) or Errata) to take advantage of current experience and understanding. An official NFPA Standard at any point in time consists of the current edition of the document, including any issued TIAs and Errata then in effect.

To determine whether an NFPA Standard has been amended through the issuance of TIAs or corrected by Errata, visit the “Codes & Standards” section on NFPA’s website (www.nfpa.org).


Updating of AGA and NFPA Standards

Users of NFPA codes, standards, recommended practices, and guides (“NFPA Standards”) and AGA Z223.1 should be aware that these documents may be superseded at any time by the issuance of new editions or may be amended from time to time through the issuance of Tentative Interim Amendments or corrected by Errata. An official NFPA or AGA document at any point in time consists of the current edition of the document together with any Tentative Interim Amendments and any Errata then in effect. In order to determine whether a given document is the current edition and whether it has been amended through the issuance of Tentative Interim Amendments or corrected through the issuance of Errata, consult appropriate NFPA publications such as the National Fire Codes® Subscription Service, visit the NFPA website at www.nfpa.org, or contact the AGA or NFPA at the addresses listed below.

Interpretations of AGA and NFPA Standards

A statement, written or oral, that is not processed in accordance with the interpretation procedures of the Z223 Committee or Section 6 of the Regulations Governing the Development of NFPA Standards shall not be considered the official position of the Z223 Committee or the NFPA or any of their respective Committees and shall not be considered to be, nor be relied upon as, a Formal Interpretation.


Neither the AGA nor the NFPA take any position with respect to the validity of any patent rights referenced in, related to, or asserted in connection with an AGA or NFPA document. The users of AGA and NFPA documents bear the sole responsibility for determining the validity of any such patent rights, as well as the risk of infringement of such rights, and the AGA and NFPA disclaim liability for the infringement of any patent resulting from the use of or reliance on AGA and NFPA documents.

AGA and NFPA adhere to the policy of the American National Standards Institute (ANSI) regarding the inclusion of patents in American National Standards (“the ANSI Patent Policy”), and hereby give the following notice pursuant to that policy:

NOTICE: The user’s attention is called to the possibility that compliance with an AGA or NFPA document may require use of an invention covered by patent rights. AGA and NFPA take no position as to the validity of any such patent rights or as to whether such patent rights constitute or include essential patent claims under the ANSI Patent Policy. If, in connection with the ANSI Patent Policy, a patent holder has filed a statement of willingness to grant licenses under these rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such a license, copies of such filed statements can be obtained, on request, from NFPA. For further information, contact the NFPA at the address listed below.

Law and Regulations

Users of NFPA Standards should consult applicable federal, state, and local laws and regulations. NFPA does not, by the publication of its codes, standards, recommended practices, and guides, intend to urge action that is not in compliance with applicable laws, and these documents may not be construed as doing so.


NFPA Standards are copyrighted by the NFPA. They are made available for a wide variety of both public and private uses. These include both use, by reference, in laws and regulations, and use in private self-regulation, standardization, and the promotion of safe practices and methods. By making these documents available for use and adoption by public authorities and private users, the NFPA does not waive any rights in copyright to these documents.

Use of NFPA Standards for regulatory purposes should be accomplished through adoption by reference. The term “adoption by reference” means the citing of title, edition, and publishing information only. Any deletions, additions, and changes desired by the adopting authority should be noted separately in the adopting instrument. In order to assist NFPA in following the uses made of its documents, adopting authorities are requested to notify the NFPA (Attention: Secretary, Standards Council) in writing of such use.
