Wet chemical fire-extinguishing systems for use in cooking operations shall comply with _________.

• A. NFPA 12
• B. ANSI/UL300
• C. UL 180
• D. ASTM F2328

Answer: (B)

Wet chemical kitchen fire suppression systems are specialized for cooking operations and must meet a standard that specifically addresses their design, performance, and installation. ANSI/UL 300 is the standard that covers these wet chemical systems—the components, discharge mechanism, agent (typically potassium acetate), and testing requirements to ensure reliable suppression of cooking-oil fires without damaging the kitchen. This standard provides the recognized criteria used by manufacturers and authorities having jurisdiction to approve and install these systems, which is why it is the best fit for compliance. Other standards referenced relate to different fire-protection technologies or equipment and do not address the unique aspects of wet chemical systems for commercial kitchens.
