Who is typically responsible for WCFS inspection, testing, and commissioning?

• A. Restaurant owner
• B. HVAC technician
• C. A fire protection contractor
• D. Local health department

Answer: (C)

WCFS, or wet chemical kitchen fire suppression systems, require specialized knowledge to inspect, test, and commission. A fire protection contractor is trained to verify all aspects of the system—from agent concentration, cylinder pressure, and discharge nozzles to integration with detection and alarm components—ensuring the system is installed and maintained to NFPA 17A and manufacturer guidelines. This level of expertise and access to the right tools is why a contractor is the typical responsible party.

The restaurant owner may operate the kitchen safely but does not have the formal training or licensing to perform professional testing. An HVAC technician focuses on the ventilation system, not the fire suppression network. The local health department handles food safety and health compliance, not fire protection testing.
