Fire Door Inspection Hampshire

How do fire doors work?

Fire doors are made up of various components which when successfully tested are certificated as fire door assembly. They are given a rating which gives its performance. For example an FD30 door would be certificated to provide a barrier to fire for up to 30 minutes.

Fire doors on rooms and corridors will be fitted with door closers which will automatically pull the door into the closed position after someone has passed through it.

The edges of fire doors are fitted with intumescent seals which when exposed to heat swell and seal the gap between the door and the frame. Smoke seals are often also fitted and prevent smoke from seeping around the edges of the door.

What are fire doors?

Fire doors are specialist doors which have been tested and certificated to hold back and withstand fires for a defined period of time. When closed fire doors provide a barrier to the passage of fire and smoke. This helps to prevent or slow down the spread of fire from one part of a building to another. Another important thing that fire doors provide a barrier to is the passage of smoke. This helps seal of escape routes and stairways to prevent them filling with smoke and preventing the occupants escaping a building.

Fire doors will normally be identified by the blue circular signs fitted to them which will normally say “fire door keep shut” or “fire door keep locked”.
