Why is it important to close doors during a fire?
A closed door can limit the oxygen to a fire; since the oxygen consumed by a fire is directly proportional to the energy it produces, the closed door will slow the fire growth. Since we have seen that fires are burning and spreading faster, anything we can do to slow them down will benefit us and THEM.
Should you close doors and windows in a fire?
Close all your internal doors to prevent smoke spreading if a fire starts. Never smoke in bed it’s best to quit but, if you can’t, swap for an e-cigarette. Make sure escape routes are clear of anything that may slow you down. Keep door and window keys where everyone you live with can find them.
Can you use a fire exit as a normal door?
We’re sometimes asked, incidentally, whether a designated fire exit can also legally be used as a regular entrance/exit door i.e. for every day use. The answer is yes it can indeed the fact that it is in daily use makes it ideal as an escape route as its location is well known.
Why should internal fire doors remain closed?
It is dangerous to wedge or prop open a fire door as the safety of occupants cannot be guaranteed if there is a fire. Fire doors need to be closed to prevent the spread of fire and smoke.
Do fire doors need to be closed at all times?
Fire doors have to be kept close at all times unless certified fire door retainers are installed (not just a door wedge!) which hold the fire door open until a fire alarm is set off.
Should fire doors be locked at all times?
Fire exit doors must not be locked or fastened in a way preventing them being easily and immediately opened by any person who may use them in an emergency. The door can, at all times, be used for non-emergency purposes by a key holder.

What is the difference between a fire door and a normal door?
Fire doors are given a fire-resistance rating, and are usually made of a combination of glass, gypsum, steel, timber and aluminium. They are designed to be kept closed, and any gaps between the wall and the door must be filled with a fire resistant sealant.

Most of the wood doors have a 20-minute fire rating. However, the MDF (medium density fiberboard) doors are available in 20-minute, 45-minute, 60-minute, and 90-minute fire ratings. Homeowners can choose from a variety of wood species and styles, to ensure that the fire-rated doors match the rest of the home’s styles.
What makes a door fire resistant?
The door itself is usually made from a solid timber frame, but they can sometimes be covered again in fire-resistant glass. Around the edges of the door will be the intumescent seal, which is designed to expand when temperatures reach beyond 200°C to seal the gaps between the door and frame.
What makes a 20 minute fire rated door?
20 minute without hose stream: These are openings that have successfully passed a 20 minute fire test but were not subjected to the hose stream test. 20 minute without locking/latching hardware: Some areas specify smoke and draft for air leakage only and do not require fire test nor self latching locks.
How long does a normal door last in a fire?
In serving to compartmentalise a building and/or preserve an escape route, the function of a fire door, when closed, is to provide resistance to smoke/fire for a minimum specified length of time. Typically, this is 30 minutes or 60 minutes (FD30 or FD60).
What should be done before fighting a fire?
If you don’t have the correct type or large enough extinguisher to put out the fire, it is best not to try to fight the fire. Evacuate the building immediately, closing doors and windows behind you to reduce the spread of fire. You might inhale toxic smoke.
