What type of damper is used to prevent both fire and smoke?

• A. Smoke damper
• B. Fire damper
• C. Combination fire/smoke damper
• D. Automatic damper

Answer: (C)

The combination fire/smoke damper is designed specifically to address both fire and smoke control within HVAC systems. These dampers serve a dual purpose: they are equipped to close off ducts in the event of a fire, thereby preventing the spread of flames, while also sealing off areas to inhibit smoke migration. By functioning simultaneously in both capacities, these dampers ensure a higher level of safety in buildings, complying with NFPA standards, particularly in situations where the spread of smoke poses a significant risk to life and property. Unlike smoke dampers, which focus solely on controlling smoke, or fire dampers, which only restrict fire spread, the combination fire/smoke damper integrates features from both types, making it an essential component in systems designed to meet comprehensive safety regulations. Thus, its use is critical in enhancing the effectiveness of smoke and fire management in buildings, ensuring that both hazards are adequately addressed.
