The fire damper shall be listed for such use or be part of a listed exhaust hood ______.

• A. With or Without Exhaust Damper
• B. With Exhaust Damper
• C. Without Exhaust Damper
• D. Integrated Damper

Answer: (A)

In kitchen fire protection, any damper that stops flames from traveling through the exhaust duct must be a listed device for that specific use. The fire damper can either be a standalone unit that is listed for use in exhaust systems, or it can be part of a listed exhaust hood assembly. The system may include an exhaust damper or not, but the important point is that the damper accompanying the hood must have proper listing that covers its role in an exhaust/hood combination. This ensures the damper’s materials, actuation, and performance have been tested for fire exposure in that exact application, providing reliable containment in a fire.
