A fire door only works when it is closed. That sounds obvious, but it is the single most common way fire doors fail in practice: propped open with a wedge, held by a fire extinguisher, or fitted with a closer that no longer pulls the door fully shut. A perfectly specified, perfectly maintained fire door standing open offers no protection at all.
This article explains how self-closing devices are supposed to work, when it is acceptable to hold a fire door open, and the closer faults inspectors see most often.
Most fire doors are required to be self-closing. The device, usually an overhead closer, must return the door from any open position and close it fully into the frame so that the latch engages. The test an inspector applies is straightforward: open the door to various angles, including just a few degrees, release it, and confirm it closes completely and latches every time, not just from wide open.
The closing action also needs to be controlled. A door that slams can be a hazard and can damage the assembly over time; a door that closes too slowly or stalls part-way may not shut before smoke spreads. A correctly adjusted closer does the job reliably and at a sensible speed.
Fire doors are part of a building's compartmentation, the division of a building into areas that contain fire and smoke. A door that is ajar, or that closes against the frame but does not latch, leaves a gap that fire and smoke move through. Latching matters because the pressure generated by a fire can push an unlatched door open. This is why "closes but does not latch" is recorded as a failure, not a minor note.
There are legitimate reasons to want a fire door held open: accessibility, heavy traffic routes, or simple convenience in a busy corridor. The rule is that a fire door may be held open only by a device that automatically releases it on fire detection, so the door closes when the alarm sounds. Acceptable approaches include:
What is never acceptable is holding a fire door open with a wedge, a hook, a tied-back cord, an extinguisher or any other object that will not release in a fire. These are among the clearest and most serious failures an inspector can find.
The faults inspectors record most often include:
Many of these develop gradually as a closer wears, which is why regular checks catch them before they become a problem. They tie into the wider inspection checklist and the standards in BS 8214.
Closers and hold-opens are also where occupant behaviour shows up most. Doors get wedged because they are inconvenient. Part of meeting the Fire Safety (England) Regulations 2022 duty to inform residents is helping people understand why a fire door must be allowed to close, and giving them an easy way to report a closer that is not working rather than wedging the door as a workaround.
DoorTRACE captures closer and hold-open checks as part of every inspection, with photos and notes, and turns any failure into a tracked defect until it is fixed and verified. Recurring closer problems on a particular door become visible across its history, so you can replace rather than repeatedly repair. See the platform or book a demo.
Fire door failures can attract a lot more than a warning. Here is how enforcement under the Fire Safety Order escalates, and what tends to trigger it.
Regulation 10 sets clear minimum frequencies for buildings above 11 metres. Here is what they are, who they apply to, and what a check actually involves.
