This Guide has been developed to assist code officials, designers, owners, evaluators and others with the application of the listing and approval requirements pertinent to the design and/or installation of hydrogen equipment as regulated by the model codes. Enables designers, users and code officials to better apply the requirements where the use of listed, labeled, certified or approved equipment or methods is required and to increase awareness and understanding of what the equipment is expected to do.
- Where approvals are required, and listed equipment is not available the Guide provides direction and/or background to assist the users with elements of consideration needed to address the requirements for safety compatible with the requirements of the code
- Increased consistency in the application of requirements with the expectation of an expedited permitting process
- Consistent application of requirements among providers, regardless of hydrogen experience results in a level playing field as the technology emerges
- 2015 International Fire Code
- 2015 International Building Code
- 2015 International Fuel Gas Code
- 2015 International Residential Code
- 2015 International Mechanical Code
- 2011 NFPA 2 Hydrogen Technologies Code
- 2015 NFPA 1 Fire Code (as used by NFPA 2 as a source document for requirements relevant to hydrogen as established by NFPA 55)
- 2013 NFPA 55 Compressed Gases and Cryogenic Fluids Code (as used by NFPA 2 as a source document for requirements relevant to hydrogen)
This document only provides guidance. It is not a regulatory document and is not intended to provide formal interpretations or positions on compliance with the codes and standards addressed therein, which can only be provided by the code development organizations or by the responsible regulatory official. It should not be assumed that the explanatory material included in the Guide can be used on a standalone basis. Requirements and explanations must be applied in accordance with the context found within the source code.
While the Guide provides methods for the AHJ to evaluate alternative approaches to certification, listing, and labeling requirements, it is not intent of the Guide to circumvent certification and listing if the AHJ determines it to be necessary for approval.
