As with several other NFPA documents, the Technical Committee for the Standard on Clean Agent Fire Extinguishing Systems (NFPA 2001) completed a structural revision and added several new chapters during the 2022 revision cycle.
- System design requirements for total flooding have moved to a new standalone chapter.
- Information on the toxicological and physiological effects of clean agent systems have been moved to their own specific annex.
- A new chapter on impairments has been added as well.
- New clean agents such as Halocarbon Blend 55 (HB-55) and 60-bar FK-5-1-12 systems are now included in the Standard.
There are several other important changes. Be sure to review the forward of the 2022 Standard for more key information.
