What is required for a fire damper to meet NFPA standards?

• A. It must be listed and tested according to UL standards
• B. It must be painted with fire-retardant paint
• C. It must be installed at an angle
• D. It does not require any specific testing

Answer: (A)

For a fire damper to meet NFPA standards, it is essential that it is listed and tested according to UL (Underwriters Laboratories) standards. This requirement ensures that the fire damper has been evaluated for its performance in controlling the spread of smoke and fire within an HVAC system. The UL testing process confirms that the damper can withstand high temperatures and effectively close off airflow in the event of a fire, thus protecting the integrity of fire-rated walls and ceilings. This listing and testing is crucial for ensuring reliability and compliance with safety regulations, providing assurance that the fire damper will perform as intended during a fire scenario. Meeting these standards is fundamental for any fire protection device used within building systems to ensure occupant safety and property protection. Thus, adherence to UL standards forms a cornerstone of reliable fire safety practices in HVAC installations.
