BS EN ISO 7010 explained
The unified British, European, and international standard for UK safety signage. Why it matters and how to specify to it.
By Direct Signs Team · ISO 9001 certified UK manufacturer · Updated April 2026
The short answer
BS EN ISO 7010 is the unified British, European, and international standard for safety signs and signals. It defines the precise colour, shape, and pictogram for every safety sign category — prohibition (red circle with diagonal line), warning (yellow triangle), mandatory (blue circle), safe condition (green rectangle), and fire-fighting equipment (red square or rectangle). It superseded the older BS 5499-1 in 2013 and is the standard required by the UK Health and Safety (Safety Signs and Signals) Regulations 1996.
What BS EN ISO 7010 covers
The standard specifies:
- Colour — exact RAL/Pantone references for the red, yellow, blue, and green used in safety signs
- Shape — precise geometry for circles, triangles, rectangles, and the diagonal-line prohibition mark
- Pictogram — the specific symbols inside each shape (running man for fire exit, hard hat for mandatory, etc.)
- Identifier system — every pictogram has a unique code (P001, M001, W001, E001, F001) for unambiguous specification
- Sizing principles — character height ratios for legibility at viewing distance (the 1-in-200 rule)
The five categories
BS EN ISO 7010 organises all workplace safety signs into five categories, each with a distinct colour-and-shape combination:
- Prohibition (P-prefix) — red circle with diagonal line. "Must not." P002 No smoking, P003 No naked flame.
- Mandatory (M-prefix) — solid blue circle. "Must do." M001 Wear hard hat, M008 Wear safety footwear.
- Warning (W-prefix) — yellow triangle with black border. "Be aware of hazard." W001 General hazard, W012 Electricity hazard.
- Safe condition (E-prefix) — green rectangle. "Safe option here." E001 Emergency exit, E003 First aid, E007 Emergency shower.
- Fire-fighting equipment (F-prefix) — red square or rectangle. "Equipment here." F001 Fire extinguisher, F004 Fire hose reel.

The shift from BS 5499-1 to BS EN ISO 7010
BS 5499-1 was the previous UK standard for safety signs, in force until 2013. It used different pictograms in some categories — notably, the running-man fire exit pictogram in BS 5499-1 was different from the more universally-recognised running-man in BS EN ISO 7010.
The shift to BS EN ISO 7010 in 2013 unified UK practice with European and international standards, making cross-border signage consistency much easier for multinational employers and reducing confusion for international visitors and workers in UK premises.
How BS EN ISO 7010 fits with UK regulation
Several UK regulations reference or rely on BS EN ISO 7010:
- Health and Safety (Safety Signs and Signals) Regulations 1996 — requires compliant safety signage where risks cannot be eliminated; "compliant" means BS EN ISO 7010
- Regulatory Reform (Fire Safety) Order 2005 — fire safety signage including escape routes and fire equipment must follow BS EN ISO 7010 pictograms
- Workplace (Health, Safety and Welfare) Regulations 1992 — general workplace signage
- Health Act 2006 — no-smoking signage uses the BS EN ISO 7010 P002 pictogram
See our UK safety sign regulations guide for the full mapping.
Specifying BS EN ISO 7010 signage
For procurement specifications, contracts, and audit documentation, the unambiguous reference is the BS EN ISO 7010 identifier (e.g. "P002, A4 size, photoluminescent specification, on rigid PVC substrate"). Direct Signs supplies signage with full BS EN ISO 7010 traceability — the identifier is shown on every product page, and we maintain BS EN ISO 7010 compliance documentation for audit purposes.
Updates and revisions
BS EN ISO 7010 is periodically updated as new pictograms are added or existing ones revised. The current version is BS EN ISO 7010:2020+A1:2024. Recent additions include:
- AED / defibrillator pictogram (E024)
- Drone no-fly zone signage
- Updated photoluminescent technical references
- Cyber-security and information-security signage
Direct Signs maintains current revision compliance — newly manufactured signs reference the latest BS EN ISO 7010 version.
