Fire doors

Fire doors should be capable of containing a fire within an effective area while

allowing people safely to vacate the affected area.

They should also reduce the risk of a fire spreading to another area, as well as

limiting the movement of smoke.

The main purpose of a fire door is to provide a barrier to reduce the passage of

fire and smoke.

When a door is in its closed position, it should provide fire resistance to satisfy

current fire regulations.
