How often shall hoods, fire-actuated dampers, and internal washing components be inspected and tested?

• A. Every 3 months
• B. Every 6 months
• C. Every 12 months
• D. Every 24 months

Answer: (B)

Regular maintenance for kitchen hood fire-suppression components is performed every six months. This interval keeps grease buildup under control and ensures mechanical parts like fire-actuated dampers and their actuators are functioning and properly aligned. Hoods should be checked for damage, corrosion, and obstructions that could affect performance. Internal washing components must be inspected to confirm no clogs or leaks and that the wash system activates correctly, delivering the intended rinse to protect the system. Doing this twice a year balances safety with practicality, catching wear or fouling before it can compromise activation, while avoiding unnecessary frequency. Shorter intervals would be overly frequent, and longer intervals risk undetected faults that could hinder performance in a fire.
