Hazardous Area Signs help you warn staff, contractors and visitors before they enter workplaces, stores or site areas where general risks need clear attention
Hazardous Area Signs warn people that they are approaching or entering an area where a general hazard may be present. They help you guide staff, contractors and visitors in workshops, stores, plant rooms and site entrances so caution starts before exposure to risk.
Where Hazardous Area Signs Should Be Positioned
You should install this sign at the first point where someone may step into a hazardous area, such as plant room doors, chemical stores, machinery rooms, service corridors, loading entrances and restricted workspaces. Clear placement helps people slow down before the risk is reached.
Choosing a Practical Viewing Distance
Match the sign size to the approach distance. Use larger signs for vehicle routes, wide entrances and busy work areas, and smaller signs for doors, cupboards or close-range cabinet warnings.
| Size | Best viewing range | Typical placement |
|---|---|---|
| H 600 x W 450 mm | 20–25 metres | Large entrances and site routes |
| H 420 x W 297 mm | 12–18 metres | Workshops and plant access |
| H 297 x W 210 mm | 8–12 metres | Doors and internal corridors |
| H 210 x W 148 mm | 4–7 metres | Cupboards, cabinets and close access points |

❌ Do not place it so high that people miss it during normal approach.
❌ When this sign is not enough on its own

Hazardous Area Signs questions answered
What are Hazardous Area Signs used for? They warn people that a general hazard may be present before they enter the area, helping you create caution at the right point.
Is W001 the correct symbol for this sign? Yes. W001 is the EN ISO 7010 general warning symbol, used where a broad hazard warning is needed rather than one specific hazard symbol.
Should I use this instead of a chemical, electrical or forklift warning sign? Use this for general hazard awareness. If the risk is specific, add the correct dedicated warning sign so people know exactly what they are facing.
Where should I put a hazardous area sign? Fit it before entry points, doors, barriers, plant rooms, stores, maintenance spaces and any access route where people need warning before entering.
Which material should I choose? Choose self-adhesive vinyl for smooth indoor surfaces and rigid plastic where you need a more durable sign on walls, doors, fences or outdoor sheltered positions.
