Which standard provides the foam concentrate level check frequency?

• A. NFPA 11 2016
• B. NFPA 11 2013
• C. NFPA 25 2016
• D. NFPA 70 2016

Answer: (A)

Foam concentrate level checks are specified under the foam fire protection system standard. NFPA 11 governs the design, installation, and maintenance of foam systems, including requirements for how often the foam concentrate level must be checked. The 2016 edition is the version referenced for current practice in this context, making it the source of the required frequency. The other standards shown address different areas—NFPA 25 covers general inspection and maintenance of water-based systems (not the specific foam concentrate level check frequency), NFPA 70 is the electrical code, and NFPA 11 from the 2013 edition would be an older version.
