2018 International Building Code

A modification to Section 904.14 (Aerosol Fire Extinguishing Systems) states that the installation, inspection, testing and maintenance of aerosol fire-extinguishing systems are now addressed through applicable references to Sections 901 and 904.4 of the International Building Code and NFPA 2010, as well as the system’s listing and manufacturer’s instructions.

NFPA 2010 Standard for Fixed Aerosol Fire Extinguishing Systems was first published in 2006. Since then, the International Code Council Evaluation Service (ICC-ES) has published the ICC-ES Acceptance Criteria for Fixed Condensed Aerosol Fire-Extinguishing Systems, AC432. In 2014, ICC-ES published evaluation report ESR-3230 for an aerosol fire-extinguishing system in compliance with the 2009 and 2012 editions of the International Fire Code as an alternative to International Fire Code Section 904.9, Halon Fire-extinguishing Systems. The International Building Code now addresses the installation, inspection, testing and maintenance of aerosol fire-extinguishing systems through applicable references to Sections 901 and 904.4 of the IBC and NFPA 2010, as well as the system’s listing and manufacturer’s instructions.
