What do fire/smoke dampers help prevent in a building during a fire event?

• A. Airflow disruption
• B. Smoke spread and fire penetration
• C. Structural damage
• D. HVAC system failure

Answer: (B)

Fire and smoke dampers are specifically designed to prevent the spread of smoke and fire through the HVAC system and maintain compartmentalization within a building during a fire event. When a fire occurs, the damper automatically closes, creating a barrier that restricts the movement of fire and smoke from one area to another, thereby protecting occupants and allowing for safer evacuation and firefighting efforts. This crucial function helps limit the damage associated with a fire, maintains safe escape routes, and prevents smoke from traveling through the ductwork to other parts of the building, which can be particularly hazardous. Their role is vital in achieving a well-coordinated fire protection strategy as mandated by various NFPA standards.
