Fire smoke dampers are critical parts of passive fire protection systems that protect a building and its occupants from the spread of smoke and flames throughout the building’s HVAC system. In order for fire smoke dampers to be effective, they need to be functioning and maintained to NFPA standards.

These are the requirements fire smoke dampers must meet on inspection, according to the NFPA*:

• Damper inspection includes verification that all equipment is installed in accordance with the manufacturer’s instructions and that proper access is available.
