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

• A. ANSI/UL300
• B. NFPA 17
• C. UL 300
• D. ASTM F2909

Answer: (A)

Wet chemical fire-extinguishing systems for commercial cooking equipment are guided by a listing/recognition standard that specifies how these systems must be designed, installed, and maintained. ANSI/UL 300 establishes the requirements for restaurant fire-extinguishing systems, including those using wet chemical agents, covering aspects such as agent type, nozzle patterns, coverage of hoods and cooking appliances, actuation, cylinder ratings, labeling, testing, and maintenance. This standard ensures the system will reliably control and suppress cooking-oil fires and compatible components throughout the kitchen exhaust system.

The ANSI/UL 300 designation is the formal reference used by codes and manufacturers, and in practice UL 300 and ANSI/UL 300 refer to that same standard, with the ANSI-accredited version being the one commonly cited in code language. Other standards like NFPA 17A or ASTM F2909 address different fire-protection topics and do not specifically govern the wet chemical systems used for cooking operations in the same way.
