What is the function of a fire damper?

• A. To control humidity levels
• B. To close automatically during a fire
• C. To enhance airflow throughout a building
• D. To act as a sound barrier

Answer: (B)

The function of a fire damper is primarily to close automatically during a fire. Fire dampers are critical components of fire protection systems within HVAC systems, designed to prevent the spread of fire and smoke through ductwork and between different compartments of a building. When a fire is detected—typically through the activation of a fire alarm system—the fire damper will close, thereby isolating the fire and stopping it from moving into areas that may not be affected. This automatic closure is an essential feature, as it helps to safeguard occupants and reduce property damage during a fire incident. Control of airflow, humidity levels, and sound isolation are important aspects of HVAC systems, but they do not pertain to the primary function of a fire damper, which is to act as a critical barrier during fire emergencies.
