Danger Explosive Atmosphere ATEX Category 1 Sign helps safety managers warn staff, contractors and visitors before entering high-risk fuel, gas, solvent or dust handling areas.
Danger Explosive Atmosphere ATEX Category 1 Sign warns you, your staff and contractors that flammable material may be present during normal operation. Use it at access points, plant rooms, fuel stores and handling areas where ignition control is critical.
Where Danger Explosive Atmosphere ATEX Category 1 Signs Should Be Fitted
You should install this sign at entrances, doors, cabinets and approach points before people reach the hazard. Place it where eyes naturally pause, not after the risk area, so staff, contractors and visitors understand the explosive atmosphere warning before opening, switching or entering.
Practical Viewing Distance Guidance
Choose the larger size where people approach from open walkways, yards or plant routes. Use the smaller size on cupboards, internal doors or close-range equipment locations where the reader is usually within a few metres.
| Size option | Typical viewing distance | Best use |
|---|---|---|
| H 297 x W 210 mm | Up to around 10 metres | Entrances, plant rooms, fuel stores and approach routes |
| H 150 x W 125 mm | Up to around 4 metres | Cabinets, cupboards, doors and close-range warning points |
What Should Improve After This ATEX Warning Is Displayed
After installation, the sign helps turn a hidden process hazard into a clear decision point. People are more likely to slow down, avoid ignition sources and check controls before entering or working near the marked explosive atmosphere area.
✅ Staff pause before entering areas where flammable material may be present
✅ Contractors recognise that normal work controls may not be enough
✅ Ignition risks are challenged earlier, before tools or equipment are used
