Which NFPA standard covers the installation of Foam-Water Sprinkler and Foam-Water Spray Systems?

• A. NFPA 14
• B. NFPA 16
• C. NFPA 30B
• D. NFPA 20

Answer: (B)

Foam-water sprinkler and foam-water spray systems have their own dedicated installation standard because they involve mixing foam concentrate with water to create a foam solution for extinguishing fires involving flammable liquids. The standard that covers how to design, install, test, and maintain these foam systems is NFPA 16. It guides the selection of foam concentrates, the proportioning equipment, piping, and overall system layout to ensure the foam solution is produced and delivered properly, reliably, and safely.

The other standards address different fire protection topics: NFPA 14 deals with standpipe and hose systems, NFPA 30B covers storage of flammable and combustible liquids (outside of foam-system installation specifics), and NFPA 20 covers the installation of stationary fire pumps. None of these provide the required installation guidelines for foam-water sprinkler or foam-water spray systems.
