What is the typical role of a fire protection contractor in an inspection?

• A. To approve AHJ sign-offs.
• B. Conduct professional inspection, testing, and commissioning of WCFS and related components.
• C. Manufacture WCFS components.
• D. Provide insurance coverage.

Answer: (B)

The main idea is that a fire protection contractor is responsible for performing the professional inspection, testing, and commissioning of the wet chemical fire suppression system and its related components. This means they verify that the system is properly installed and wired, all nozzles and discharge devices are correctly placed and unobstructed, the detection and release circuits function as designed, the agent is properly charged, and the overall system will operate correctly in a fire. They document the results, ensure all tests meet the applicable standards, and provide the necessary information for the AHJ to review. Sign-offs from the Authority Having Jurisdiction, manufacturing of system parts, and general insurance coverage are not the contractor’s inspection role, so the best-fit description is conducting inspection, testing, and commissioning of the WCFS and its components.
