By performing a basic check, you can quickly identify potential problems. Here are five key areas to inspect:
- The Gap Test
The gap between the door and its frame should be consistent and no wider than 3mm. A simple test with a £1 coin (which is approx. 3mm thick) can help. You should not be able to slide the coin through the gap. If the gap is too large, it can allow fire and smoke to pass through.
- The Seals
Inspect the intumescent seals and smoke seals around the door frame. These are often integrated into the frame or door edge. The seals should be undamaged and sit firmly in their grooves. If you spot any peeling, tearing, or damage, the seal will not work as intended during a fire.
- The Hinges
Check that the hinges are firmly screwed into the door and the frame. All hinges should be present, and none should be loose, broken, or missing screws. If the hinges are not secure, the door may not close correctly, or it could even fall off in a fire.
- The Closer
The door closer is a critical piece of hardware that ensures the door shuts on its own. It’s a legal requirement for most fire doors. To check it, open the door partway and let it go. It should close firmly and completely, without slamming. A door that doesn’t close fully provides a pathway for smoke and fire.
- Damage and Integrity
Look for any signs of damage on the door itself. Holes, cracks, or unauthorized modifications can compromise its fire resistance. You should also check the door glazing (if applicable) for damage and ensure it has the correct fire-rated markings. Never assume a damaged door is still safe.
