What is an important consideration when installing fire dampers?

• A. Distance from electrical equipment
• B. Proper alignment with ductwork
• C. Appearance and color
• D. Proximity to windows

Answer: (B)

Proper alignment with ductwork is crucial when installing fire dampers because it ensures that smoke and fire can be effectively contained and controlled within the duct system. If fire dampers are not correctly aligned with the ductwork, they may not seal appropriately during a fire event, allowing smoke and potentially flames to bypass the damper and spread to other areas of the building. This misalignment can compromise the effectiveness of the fire protection system, leading to increased risk during a fire incident. In addition, proper alignment aids in maintaining the functional integrity of the HVAC system, ensuring that airflows are not obstructed and that the damper operates as intended. Compliance with NFPA standards requires that fire dampers be installed in a manner that allows them to perform their intended purpose, which is primarily to prevent the spread of fire and smoke through duct openings.
