Which fire door sign is appropriate?
“Fire door keep shut” is used where a self-closing door must not be held open. “Fire door keep locked” is used for doors such as certain cupboards or risers that should remain secured and are not part of an escape route. Automatic doors may need signs explaining that they must be kept clear.
The message should match the fire strategy and actual operation. A keep-locked instruction must never obstruct a required escape route.
| Message | Typical intent | Common mistake |
|---|---|---|
| Fire door keep shut | Preserve a self-closing fire barrier | Door wedged open despite the sign |
| Fire door keep locked | Protect a non-escape cupboard, riser or plant space | Applied to a required exit |
| Automatic fire door keep clear | Allow released door to close | Furniture placed in the sweep path |
Placement
Where should signs be fitted?
Position and visibility should allow people to understand the instruction before operating or obstructing the door. The exact need can vary by premises and by which face is seen by residents or members of the public.
Signs should be maintained, legible and not cover certification marks, glazing or other essential information. Avoid adding screws or large fixings outside the permitted doorset detail.
- Correct wording for the door function
- Visible from the relevant approach
- Secure without harmful alteration
- Legible and maintained
- Consistent with emergency and access arrangements
Management, not proof
What does a fire door sign prove?
A sign proves very little about construction, rating, installation or condition. It is a management control and identification aid, not certification.
If a door is missing a sign, add it only after confirming the intended function. If the door fails to close, is damaged or has uncertain evidence, signage alone does not close the defect.
