What is the primary purpose of post-installation performance testing of a kitchen exhaust system?

• A. To decorate the facility
• B. To verify airflow, filtration, fire suppression, and interlocks meet design intent and safety codes
• C. To increase noise levels
• D. To reduce work hours

Answer: (B)

The main idea this question tests is that post-installation performance testing verifies the system actually performs as designed and complies with safety codes. After the kitchen exhaust is installed, technicians measure and confirm that the airflow at the hood meets the designed CFM and face velocity, that filtration remains effective and properly installed, and that the fire suppression system operates correctly and is properly integrated with the ventilation controls. They also check interlocks and safety circuits to ensure, for example, that activating the fire system or emergency signals appropriately stops fans and triggers alarms as required. This testing confirms adherence to design intent and applicable codes (such as NFPA 96 and related local regulations), ensuring the system will control grease, prevent fire spread, and protect occupants. Decoration, higher noise, or simply reducing work hours aren’t purposes of this testing. Those outcomes do not reflect the safety, performance, and code-compliance verification that post-installation testing provides.
