Fire doors are always important, but it can be even more crucial for those who manage buildings with a sleeping risk such as hotels and hospitals. The condition of each door can dramatically impact the performance of the door to hold back, smoke, gasses and fire. Here are some simple things to keep in mind to ensure that the resident’s premises and their occupants remain protected. A fire door is only effective barrier to fire (and possibly smoke) when its shut.

prop open fire doors

So, the residents must make sure that their fire doors close fully against the rebated stop of the door frame. This is why, well maintained hinges, closers, locks and latches are so crucial to fire door performance. Never prop open fire doors even for a short period to vacuum the floor. Some of the most common faults are ones that stop the door closing properly.

Hinges – If hinges are not fitted and maintained correctly the door may drop and bind on the floor or door frame.

Closers – If the closer is too weak or incorrectly adjusted it may not close the door effectively.

Lock and latches – If the lock or latch is unsuitable or if the strike is incorrectly angled again the door may not close properly.

Gaps and Seals

If the resident can see daylight between the smoke brush and the door edge or frame, then urgent attention is needed

Intumescent seals must be fitted to all fire doors. These seals will expand in a fire situation and seal the gap around the perimeter of the closed door to help hold the door in place and restrict the passage of fire. Smoke seals will restrict the spread of cold smoke and do a very important job to help restrict passage of lethal smoke and gases to help save lives and keep escape routes clear of smoke.

If the smoke seal is not in full contact with the door edge and frame then it won’t effectively restrict the passage of smoke and will increase the risk of death and injury. If the resident can see daylight between the smoke brush or blade and the door edge or frame, then urgent attention is needed. Gaps around the perimeter of the door are very important to ensure correct performance of the intumescent seals in a fire situation.

Implement effective inspection

Best practice guidance is a 3mm gap between the door edge and frame around the perimeter and 8 to 10mm maximum at the threshold (3mm where smoke protection is required). The resident should not block escape doors that people need to get out easily and the Fire and Rescue Service may need to get in to rescue anybody trapped inside, not to mention extinguish the fire.

Legal Obligations of the residents are:

  • Be aware of the legal obligations regarding the upkeep of fire doors and escape doors.
  • Understand what makes a fire door effective and what may make it ineffective.
  • Seek advice from competent persons.
  • Implement an effective inspection and maintenance program undertaken by competent persons.
