What is passive fire stopping?
Put simply passive fire stopping is the method of reinstating the fire separating elements of a building such as the walls, floors or doorways where they have been breached by linear construction gaps or penetrating items such as pipes, combustible pipes, cables, ducts, vents, escape corridors or door openings. Tested and certified single manufacturer systems are used to reinstate the elements to stop or slow down the passage of fire, heat, smoke and toxic unseen gasses, by offering a stable product to ensure the integrity of the element to achieve its fire performance. Fire Stopping products insulate against excessive heat transfer to the unaffected side of the fire separating element, to protect against furnishings, wall or floor coverings from self-combusting, closing down of voids left by melting or failing services and air sealing to ensure that smoke and deadly unseen toxic gasses cannot escape to feed the fire further or suffocate and poison the occupants, preventing their escape.
Containing a fire is the single most effective way to ensure people have those vital minutes to escape safely without fear of toxic smoke impeding their view and ability to breathe. Fire Stopping also gives you the means to gain vital time to sensibly put out the fire, stop the fire from breaking through into other areas and give you the ability to reoccupy your building sooner.
