What type of maintenance is crucial for ensuring the functionality of fire dampers?

• A. Cleaning filters regularly
• B. Regular inspection and testing
• C. Replacing air conditioning units
• D. Adjusting airflow rates

Answer: (B)

Regular inspection and testing are crucial for ensuring the functionality of fire dampers because these dampers are essential components of a building's fire protection system. Fire dampers are designed to close automatically in the event of a fire, preventing the spread of flames and smoke through ductwork. Over time, factors such as dust accumulation, mechanical failures, and wear can impair their operation. Scheduled inspections enable the assessment of the damper's condition, ensuring that they operate as intended when needed most. Testing includes verifying that the dampers respond correctly to fire alarm signals and that they close properly without obstruction. This preventative maintenance helps to ensure compliance with NFPA standards, specifically NFPA 80, which outlines the requirements for the installation, inspection, testing, and maintenance of fire doors and windows, including dampers. In contrast, while regular cleaning of filters, replacing air conditioning units, and adjusting airflow rates are important maintenance tasks in HVAC systems for efficiency and performance, they do not specifically address the functional integrity of fire dampers, which rely on regular inspection and testing to ensure their readiness in case of a fire emergency.
