What NFPA standard covers dry chemical extinguishers?

The standard that specifically addresses dry chemical extinguishers is NFPA 17. This standard outlines the design, performance, and testing requirements for dry chemical fire extinguishers, including specifications for their manufacturing and associated equipment. It ensures that these extinguishers are effective in suppressing fires involving combustible materials and flammable liquids, providing guidelines for their installation, maintenance, and proper usage.

Understanding the context of NFPA standards is important. For instance, NFPA 10 deals with portable fire extinguishers in general, covering all types of extinguishers, which includes dry chemical but does not focus exclusively on them. NFPA 12 pertains to carbon dioxide extinguishing systems, which is another type of fire suppression system that does not relate to dry chemical extinguishers. NFPA 25 focuses on the inspection, testing, and maintenance of water-based fire protection systems and is not applicable to dry chemical extinguishers. Therefore, NFPA 17 is the distinct standard dedicated to ensuring the effectiveness and safety of dry chemical fire extinguishers.
