A fire door only works if it is kept in the condition it was designed for, and signage is how a building tells everyone using it what that condition is. The signs are small and easy to overlook, but they carry a genuine duty, and the wrong sign, or no sign at all, is a common inspection finding.
This guide covers which signs exist, what each one means, where they should go, and where the duty comes from. It is general information, not legal advice; the right answer for a specific door depends on the building and its fire strategy.
In England and Wales, fire safety in non-domestic premises and the common parts of multi-occupied residential buildings is governed by the Regulatory Reform (Fire Safety) Order 2005. The responsible person has to provide appropriate safety signs where a significant risk has not been avoided by other means. Signs themselves should follow the recognised conventions in BS 5499 and the ISO 7010 standard, which is why mandatory fire door signs are the familiar blue circle with white text or symbol.
The Fire Safety (England) Regulations 2022 added duties in higher residential blocks, including giving residents information about fire doors, which sits alongside physical signage rather than replacing it.
Three messages cover almost every fire door.
"Fire Door Keep Shut" goes on self-closing fire doors that should normally be closed. This is the most common sign, found throughout corridors, stairwells and lobbies. The whole point of a self-closing fire door is defeated if it is wedged open, and the sign states the expectation plainly.
"Fire Door Keep Locked" goes on fire doors that are not in regular use and are meant to be kept locked shut, such as store cupboards, riser doors and plant rooms. These doors still resist fire, but they are managed by being locked rather than self-closing.
"Automatic Fire Door Keep Clear" goes on doors that are legitimately held open by an automatic release device linked to the fire alarm, which closes them when the alarm sounds. The message tells people not to obstruct the door so it can close freely when it needs to.
As a general rule, "Keep Shut" and "Keep Clear" signs are placed where people will see them as they approach and use the door, and on communal doors they are commonly fitted to both faces so the message is visible from either side. Mandatory signs use the blue pictogram format and should be clean, legible and undamaged.
Private flat entrance doors are a nuance. In residential blocks these are fire doors, but they are controlled by the residents living behind them, and they are not generally signed with "Keep Shut" in the way a communal door is. The 2022 Regulations approach this through information to residents rather than signage on the door. The communal side of the compartment is where signage does the work.
Signage is quick to check and quick to get wrong, which is why it appears so often in findings. Common issues are missing signs, the wrong sign for the door's function, signs that have been painted over or fallen off, and held-open doors with no automatic release and a "Keep Shut" sign that is routinely ignored. None of these are dramatic on their own, but together they tell an enforcing officer how seriously fire doors are managed day to day.
A sign is also one of the easiest items to put right, which makes it a good early win on any door that needs attention. Record the signage state on each door so a missing sign becomes a tracked action rather than a note that gets lost.
DoorTRACE captures signage as part of the standard inspection, so a missing or incorrect sign becomes a logged defect with a photograph and a clear action, not a line in a report nobody revisits. Everything ties back to the building's record and the duties under the Fire Safety Order and the 2022 Regulations. To see how it works, get in touch.
The British fire test standard behind most installed fire doors is being retired in favour of European standards. Here is what changes, when, and whether your existing doors are affected.
