How often should fire and smoke dampers be inspected according to NFPA standards?

• A. Annually
• B. Every 6 months
• C. Every 3 years
• D. Every 5 years

Answer: (A)

NFPA standards stipulate that fire and smoke dampers must be inspected annually to ensure they are functioning correctly in the event of a fire. This frequency is crucial because these dampers play a vital role in preventing the spread of smoke and fire through air distribution systems. Regular inspections help identify any malfunctions, blockages, or physical damages that could compromise their effectiveness. While more frequent inspections, such as every six months, may seem beneficial, the standard identifies annual checks as the required frequency to balance safety and operational practicality. Inspections every three or five years are insufficient to ensure the dampers remain compliant with safety regulations and perform optimally in emergencies. Regular annual inspections also align with maintenance protocols for HVAC systems, underscoring a proactive approach to fire safety in buildings.
