Fire Door Signage: Which Signs, Which Doors, What the Rules Say

The sign-to-door mapping

• 'Fire door keep shut': the standard self-closing door's badge — both faces in most guidance readings, blue mandatory-style discs (BS 5499 family), eye-level-ish placement convention (~1.5m)
• 'Fire door keep locked (shut)': kept-locked fire doors — riser cupboards, service voids, plant (the keep-locked logic from the hold-open guide's exceptions); outside face primarily
• 'Automatic fire door keep clear': hold-open/free-swing devices needing their floor space respected (the device menu's signage partner) — door closes when the alarm speaks; the sign defends its path
• Final exit overlays: 'Fire exit keep clear' family on escape doors (egress signage proper being its own BS 5499 universe — the evacuation guides' wayfinding layer)
• Photoluminescent variants where lighting strategies want them; engraved/screwed formats where schools' sticker-peelers operate (the schools guide's termly-replacement lament answered in stainless)

Rules, sources and the proportionality truth

The legal thread: the Fire Safety Order requires premises signage per risk assessment (doors' operational signage included), BS 5499 supplies the visual conventions (mandatory blue discs, wording standards), and enforcement treats missing door signage as the low-hanging finding it is — trivially cheap, instantly visible, always listed. Proportionality honesty: signage neither closes doors nor seals gaps — it instructs humans and evidences management; a building with perfect signs and painted seals fails where one with modest discs and maintained doors passes. But the converse costs credibility: surveys (ours included, per the survey product) reporting unsigned door estates read 'management absent' to every subsequent reader — the £10/door line item defending the £100,000 programme's reputation. Sign with the works, replace at checks, move on.

Practical buying and placement

The procurement paragraph signage deserves: buy BS 5499-conformant discs/plates (£3–£15 per sign by format — self-adhesive for clean doors, screwed/engraved for traffic and pickers), specify within door works packages (every install/remedial/inspection visit carries stock — our vans do, per the hardware guide's van-stock principle), place consistently (both faces on keep-shuts where practice dictates, heights uniform — estates read better and audits tick faster), and fold checks into the rhythm (the five-step's signage line; termly school sweeps re-sticker as ritual). Edge cases answered in passing: glazed doors take discs on glass or frame (visibility over symmetry), heritage interiors negotiate discreet formats within consent sympathies (the heritage methods extending to vinyl), and resident-facing blocks pair door signs with the broader fire-action signage the 2022 regulations' information duties expect — one signage audit covering both layers, typically alongside the door survey.
