Which NFPA standard addresses foam extinguishing systems?

The NFPA standard that specifically addresses foam extinguishing systems is indeed NFPA 11. This standard provides guidelines for the design and installation of foam systems, which are crucial for fighting flammable liquid fires. It covers various types of foam systems, including foam-water systems and foam concentrate properties. Understanding this standard is essential for professionals working in fire protection, as it helps ensure that foam extinguishing systems are effective and reliable when needed most.

The other standards mentioned focus on different aspects of fire protection. For example, NFPA 10 pertains to portable fire extinguishers, NFPA 13 deals with the installation of sprinkler systems, and NFPA 25 relates to the inspection, testing, and maintenance of water-based fire protection systems. Thus, each of these standards addresses specific components of fire safety but does not encompass foam extinguishing systems like NFPA 11 does.
