Highly Flammable Signs help you warn staff, contractors and visitors where flammable goods are stored or handled, improving awareness around cupboards, doors and work areas
Highly Flammable Signs warn people that fire-risk substances are present, helping you guide staff, contractors and visitors around stores, cupboards, workshops and handling points. They support faster recognition before sparks, flames or unsafe behaviour create danger.
Where Highly Flammable Signs Should Be Fitted
You should install Highly Flammable Signs at the first point someone could approach, open or handle flammable goods. Fit them on store doors, cupboards, cabinets, workshop walls and outdoor access points so the warning is seen before ignition sources or casual handling become a risk.
Viewing Distance Guidance for Close-Range Fire Warnings
Use viewing distance as a practical check, not a guess. A 150 x 125 mm sign is best for close-range decisions on doors, cabinets and cupboards, usually from around 1–3 metres. For longer approaches, repeat the sign at entry points rather than relying on one small sign.
| Sign size | Best viewing use | Typical distance |
|---|---|---|
| H 150 x W 125 mm | Cabinets, cupboards, doors and small stores | Approx. 1–3 metres |
| Repeated same-size signs | Longer approaches, multiple entrances or cluttered workspaces | Place again before the hazard point |
What Should Improve Once This Sign Is Displayed
After fitting the sign, people can recognise the fire hazard before they touch, enter or store materials. That early warning helps you reduce unsafe smoking, naked flames, poor storage habits and avoidable delays during inspection or emergency response.
✅ Staff identify flammable goods before handling or opening storage
✅ Visitors and contractors receive a clear warning before entering risk areas
✅ Fire-risk behaviour is discouraged at the point it matters most

Highly Flammable Signs questions answered for safer placement
What are Highly Flammable Signs used for? They warn people that flammable goods, liquids or substances are present, so unsafe actions such as smoking, sparks, heat exposure or casual handling can be avoided.
Where should I place this sign? Place it where someone first approaches the hazard, such as a cupboard door, storage room entrance, cabinet, workshop wall or handling point.
Is the W021 pictogram suitable for flammable material warnings? Yes. W021 is the EN ISO 7010 warning symbol for flammable material, shown as a black flame inside a yellow warning triangle.
Should I choose rigid plastic or self-adhesive vinyl? Use rigid plastic where you need a more durable wall or door-mounted sign. Choose self-adhesive vinyl for smooth cabinets, cupboards and clean flat surfaces.
Will one small Highly Flammable Sign be enough? It can be enough for close-range storage points, but you should repeat the sign if people approach from different directions or the hazard is not obvious from the entrance.
