Fire

Buildings often have special purpose doors that automatically close to prevent the spread of fire and smoke. Fire doors that are improperly installed or tampered with can increase risk during a fire. Sometimes, door closer mechanisms ensure fire doors remain closed.

An additional fire risk is that doors may prevent access to emergency services personnel coming to fight the fire and rescue occupants, etc. Fire fighters must use door breaching techniques in these situations to gain access.

Doors in public buildings often have panic bars, which open the door in response to anyone pressing against the bar from the inside in the event of a fire or other emergency.
