Fire doors are a defensive method of fire safety, they are necessary to avoid the spread of fire in a building and therefore to reduce the loss of life. In the UK there were 491 fatalities from fire in buildings in 2006. Hence it is important that the right internal doors are fitted and that they are installed correctly.

These doors split a built in to segment to prevent fire from spreading up to the required period level (FD 30 resistant for 30 min.). They do need to let people walk through them quickly so they can avoid the flames. The minimum ranking is now FD30 whereas previously stated FD 20.

The legislation governing such styles of doors are now considered to be non-domestic buildings in the “Building Regulation Standards-Approved Document B-Part B” as from 2007 flats.

Both fire doors have a ranking, this classification certifies the doors adhere to BS 476 section 22 or the European BS EN 1634 standard. Doors are checked as a full device, including the frame and seals (later clarified intumescent seals) and furnishing.

How and what are seals which are intumescent. There must be a crack in the door leaf for a door to actually work, the gap must be sealed against the explosion, this is where the intumescent seals come in. If pressure is added to the seals, as in a burn, the seals widen to cover the void and thereby close the door to avoid the spread of fire and smoke.
