What Are Fire Dampers?
Fire dampers are critical components in the building’s fire safety system, designed to prevent the spread of fire and smoke through the ventilation system. They are installed where ductwork passes through fire-rated walls, ceilings, or floors, creating a barrier that halts the fire’s progress and protects escape routes and other compartments within the building.
Fire dampers operate by detecting a rise in temperature. When the temperature reaches a certain threshold, usually due to a fire, the fusible link holding the damper open melts, triggering the damper to close. This action effectively seals off the ductwork, preventing the fire from spreading through the building’s ventilation system. There are also more advanced models, such as motorized dampers, which close when triggered by a fire alarm system.
Given their crucial role in maintaining the integrity of fire compartments, regular testing and maintenance of fire dampers in Kent and London are not just recommended but legally required to ensure they function correctly in the event of an emergency
