Inspection of fire and smoke dampers in an HVAC system ensures a safe route for first responders and building occupants. But ensuring fire and smoke dampers are inspected on a regular basis in each state is a safety issue for the entire HVAC contracting industry.
Inspections ensure dampers and smoke control systems are in compliance with the International Fire Code. Damper and system failure due to mechanical issues; obstacles that keep dampers from closing; and lack of movement can drive smoke to back up into occupant rooms, causing occupants to suffer from smoke inhalation.
