What do fire doors do, and how do they work?
Did you know that the front door to your home and any doors along corridors and stairs are fire doors? Fire doors fulfil a life-saving role in preventing the spread of smoke and fire for a period dependent on their fire classification. Fire Doors help keep the levels of smoke and toxic gasses contained within the room of origin and prevent fire from moving into escape routes long enough to allow people to escape and for the fire and rescue services to gain access.
Fire doors will prevent fire moving into escape routes, and from one room to another. Most fire doors, when installed and used properly, will hold back a fire for 30 minutes or more, by which time the Fire & Rescue service would aim to be on site. For this to work, fire doors must be kept closed.
Is it ever ok to leave fire doors open?
A fire door, in the event of a fire, will only work if the door is closed. Fire doors are often wedged open, perhaps to help with a busy flow of people, or to keep air flowing in hot weather. But whatever the reason, fire doors should not be left open. Wedging open fire doors can, and has, caused fire to spread rapidly, destroying entire buildings and decreasing the time people have to evacuate safely.
In the event of a fire, if it was found that a fire door was wedged open, it could have serious legal implications including fines, and reduce the likelihood of a successful insurance claim to cover the loss of possessions or damages to property.
If it is necessary to prop or wedge open a fire door for the purpose of moving equipment for a short duration; the prop or wedge must immediately be removed on completion of the task in hand; an open fire door must never be left unattended. Next time you see a fire door wedged open; stop, think, and act. Close the door.
