Foam is an additive in sprinkler systems as specified by NFPA 25 A.13.4.5.2.2.3.B.

• A. No
• B. Only for Damp Systems
• C. Only for Wet Systems
• D. Yes, It Is Specified

Answer: (D)

Foam as an additive is addressed in NFPA 25 through a specific clause that sets out when and how foam concentrate can be used with water-based sprinkler systems. That section makes it clear that foam additives are allowed under defined conditions, including compatibility with system materials, proper proportioning, labeling, and ongoing testing and maintenance. Because the standard explicitly includes foam additives under that provision, the statement that foam is specified by NFPA 25 is correct. It isn’t a blanket requirement for all systems or limited to only one system type; rather, foam is allowed where the design and manufacturer's instructions permit, with the required controls in place.
