During post-installation testing, which aspects are checked to ensure safety and performance?

• A. Color of the ductwork
• B. Lighting levels
• C. Noise levels only
• D. Airflow, filtration, fire suppression, and interlocks

Answer: (D)

Post-installation testing focuses on confirming the system will operate safely and as designed. The aspects checked—airflow, filtration, fire suppression, and interlocks—are all essential for safety and performance. Airflow ensures the hood captures and evacuates cooking fumes at the intended rate, with proper velocity and balance throughout the ductwork. This prevents grease buildup, reduces fire risk, and maintains adequate ventilation for the cooking area and makeup air needs. Filtration confirms the grease filters are correctly installed and effective, with acceptable pressure drop and tight seals. Proper filtration protects the duct system, reduces fire hazards, and helps maintain air quality. Fire suppression readiness verifies the system is properly charged, that the control panel functions, and that the activation sequence (including any deluge or wet-chemical release) will operate automatically when needed. This ensures rapid response to a grease fire. Interlocks are tested to ensure automatic coordination between components—fans, dampers, alarms, and the fire suppression system—so that actions occur in the correct order and signal responders and occupants appropriately. The other options focus on factors like cosmetic appearance, lighting, or noise, which do not directly address safety or core performance of the exhaust system.
