Who should be consulted regarding limitations and recommendations based on listings or specific fire tests?

• A. The local fire marshal
• B. The foam-concentrate and foam-making equipment manufacturer
• C. The building owner
• D. The foam supplier's sales representative

Answer: (B)

When you’re looking for limitations and recommendations that come from product listings or from specific fire tests, the manufacturer of the foam concentrate and the foam-making equipment is the primary source. They perform or support the standardized tests, publish the data sheets, and state exactly what is approved, including any limits on application rates, compatible proportioning equipment, expansion ratios, water quality and temperature ranges, storage requirements, and other conditions identified during testing. Engineers and installers rely on that documented data to ensure the system stays within its listed performance. While authorities having jurisdiction, like the local fire marshal, enforce code compliance and other parties can provide supporting information, the authoritative guidance on listing-based limitations and test-based recommendations comes from the foam-concentrate and equipment manufacturer.
