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, are developed through a consensus standards development process approved by the American National Standards Institute. This process brings together volunteers representing varied viewpoints and interests to achieve consensus on fire and other safety issues. While the NFPA administers the process and establishes rules to promote fairness in the development of consensus, it does not independently test, evaluate, or verify the accuracy of any information or the soundness of any judgments contained in NFPA Standards.
IMPORTANT NOTICE REGARDING 2018 Edition CHICAGO ELECTRICAL CODE
(Based on the 2017 NATIONAL ELECTRICAL CODE®)
This 2018 Edition, CHICAGO ELECTRICAL CODE (Based on the 2017 NATIONAL ELECTRICAL CODE®) is based on, and in large part excerpted from, the 2017 edition of NFPA 70®, National Electrical Code. It contains amendments (both additions and deletions) to 2017 NATIONAL ELECTRICAL CODE edition as determined by the City of Chicago. The process for developing these amendments was not part of the NFPA’s standards development process and, as such, it did not occur in accordance with NFPA’s ANSI-accredited standards development process. As a result, 2018 Edition CHICAGO ELECTRICAL CODE (Based on the 2017 NATIONAL ELECTRICAL CODE) does not represent the position of the NFPA or any NFPA Technical Committee. It was created at the direction of the City of Chicago in order to provide City of Chicago with a single electrical code for application in the City of Chicago. The City of Chicago has determined that the most currently adopted version of 2018 Edition CHICAGO ELECTRICAL CODE (Based on the 2017 NATIONAL ELECTRICAL CODE) shall be used for all interpretations of fire protection related electrical safety situations in the City of Chicago.
To distinguish between the 2017 NATIONAL ELECTRICAL CODE and the 2018 Edition CHICAGO ELECTRICAL CODE (Based on the 2017 NATIONAL ELECTRICAL CODE), amendments that include new text or revised text will appear as shaded text. Amendments that include deleted text will be indicated with a bullet placed in the left hand margin.
The NFPA disclaims 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 NFPA Standards and 2018 Edition CHICAGO ELECTRICAL CODE (Based on the 2017 NATIONAL ELECTRICAL CODE). The NFPA also makes no guaranty or warranty as to the accuracy or completeness of any information published herein.
In issuing and making NFPA Standards and 2018 Edition CHICAGO ELECTRICAL CODE (Based on the 2017 NATIONAL ELECTRICAL CODE) available, the NFPA is not undertaking to render professional or other services for or on behalf of any person or entity. Nor is 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.
The NFPA has no power, nor does it undertake, to police or enforce compliance with the contents of NFPA Standards or 2018 Edition CHICAGO ELECTRICAL CODE (Based on the 2017 NATIONAL ELECTRICAL CODE). Nor does 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 NFPA and is solely the responsibility of the certifier or maker of the statement.
Updating of NFPA Standards
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).
Interpretations of NFPA Standards
A statement, written or oral, that is not processed in accordance with Section 6 of the Regulations Governing the Development of NFPA Standards shall not be considered the official position of NFPA or any of its Committees and shall not be considered to be, nor be relied upon as, a Formal Interpretation.
The NFPA does not take any position with respect to the validity of any patent rights referenced in, related to, or asserted in connection with an NFPA Standard. The users of NFPA Standards 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 NFPA disclaims liability for the infringement of any patent resulting from the use of or reliance on NFPA Standards.
NFPA adheres 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 gives the following notice pursuant to that policy:
NOTICE: The user’s attention is called to the possibility that compliance with an NFPA Standard may require use of an invention covered by patent rights. NFPA takes 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.
