Where are the proper procedures for collecting a foam concentrate sample found?

• A. The foam concentrate manufacturer's published instructions
• B. NFPA 25 2020, Section 11.4.2
• C. NFPA 25 2020, Table 11.1.1.2
• D. NFPA 72 2019, Section 9.2

Answer: (A)

The key idea is that foam concentrate sampling must follow the product maker’s specific guidance. Foam concentrates are specialized chemicals with varying formulations, and the manufacturer provides validated methods to preserve the concentrate’s properties, avoid contamination, and ensure safe, accurate testing. Their instructions cover exactly how to collect the sample, what container to use, how much to take, how to handle and label it, and when to test or test interval considerations. General standards give broad system requirements but do not prescribe the exact product-specific sampling steps for foam concentrates, and other NFPA documents focus on different aspects of fire protection (alarms, detection, general maintenance) rather than the precise sampling procedure.
