Fire safety signs and what they mean
In an emergency you don't read signs — you recognise them. The colour and shape tell you what to do before your brain catches up, if you know the code.
The colour-and-shape code
UK fire signs use a consistent system under the Health and Safety (Safety Signs and Signals) Regulations 1996 and BS EN ISO 7010. Four colours, four meanings:
- Green rectangles — safe condition. Escape routes, fire exits, assembly points, refuges and first-aid points. This is the "running man" heading through a doorway, with an arrow showing the way.
- Red — fire equipment and prohibitions. Red rectangles mark firefighting equipment (extinguishers, hose reels, alarm call points). A red circle with a diagonal bar is a prohibition — "no smoking," "no naked flames."
- Blue circles — mandatory. Something you must do: "Fire door — keep shut," "Fire door — keep locked."
- Yellow triangles — warning. A hazard to be aware of: flammable material, high voltage.
The signs that matter most
- Fire exit signs line the whole escape route — placed at every change of direction, level and junction. The final sign, above the exit door itself, has no arrow: it just reads "Fire Exit."
- The fire action notice is the step-by-step "what to do if you discover a fire" sign near exits and call points — sound the alarm, leave, don't use the lift, don't re-enter.
- Extinguisher ID signs sit above each unit, showing its type and what it's safe to use on.
- Fire door signs — the blue "keep shut" discs that keep compartmentation working.
It must carry the standard pictogram (text-only signs aren't acceptable), stay visible in a power cut (illuminated or photoluminescent), and never be obscured by stock, shelving or a propped-open door. Article 14 of the Fire Safety Order requires escape routes and exits to be signed and illuminated.
Why recognition beats reading
The whole point of a standardised code is speed. In smoke and stress, a green rectangle registers as "safety, this way" and a red one as "equipment / stop" long before anyone reads a word — but only for people who've seen the code enough to know it cold. That's a training job, not just a signage job.
Practise this in the game
The Signage drill flashes real fire safety signs at you and asks what each one means — quick recognition, the way it works in a real emergency.
