Foam is an additive in sprinkler systems according to NFPA 25 A.13.4.5.2.2.3.B.

• A. Yes
• B. No
• C. Only in Specific Systems
• D. Only in Nonfoam Systems

Answer: (A)

Foam additives are used in certain water-based sprinkler systems, and NFPA 25 explicitly addresses foam concentrates in its annex. The guidance in A.13.4.5.2.2.3.B makes clear that when a foam concentrate is used, it must be stored properly, proportioned correctly into the water stream, and maintained with appropriate testing and equipment checks (such as proportioners and compatibility with system components). This shows that foam can indeed be an additive in sprinkler systems, provided the system is designed for it and kept up to standard maintenance. That’s why the answer is Yes. The other options imply that foam has no place or is limited in ways not supported by the NFPA 25 annex guidance, which isn’t accurate for systems configured to use foam concentrates.
