High Temperature signs help you warn staff, contractors and visitors in boiler rooms, workshops, kitchens, plant rooms and process areas before heat becomes a contact or access risk.
High Temperature signs warn people that heat may be present around equipment, rooms or process areas. They help you protect staff, contractors and visitors in plant rooms, kitchens, workshops and manufacturing sites where contact, radiant heat or unsafe entry could cause injury.
Where High Temperature Signs Should Be Positioned
You should install these signs at eye level before people reach ovens, boilers, hot pipework, furnaces, drying areas or heated machinery. Clear visibility matters because it gives staff and visitors time to slow down, keep distance and use the right precautions before entering the risk area.
Viewing Distance Guidance for High Heat Warnings
Choose a size that matches the approach distance. Smaller signs suit close-range doors and equipment faces, while larger formats help across workshops, plant rooms and production routes where people need earlier warning.
| Size option | Best viewing use | Practical distance |
|---|---|---|
| H 150 x W 125mm | Close equipment faces | Up to 2 metres |
| H 210 x W 148mm | Doors and small work areas | 2–4 metres |
| H 297 x W 210mm | Plant rooms and workshops | 4–7 metres |
| H 420 x W 297mm | Larger process areas | 7–10 metres |
What Should Improve After High Temperature Signage Is Fitted
Once fitted in the right place, the sign should prompt people to pause before approaching hot equipment, choose safer routes, wear suitable protection and avoid casual contact with surfaces or areas that may not look dangerous at first glance.
✅ Staff recognise heat risk before reaching the hazard point.
✅ Contractors know where caution is needed during servicing.
✅ Visitors are less likely to enter heated areas casually.

Installing High Temperature Signs Without Reducing Their Impact
Heat warning placement errors
❌ Fitting the sign too close to the hot point, after the person has already entered the risk area.
❌ Mounting it behind open doors, stored materials or pipework where it becomes hidden.
❌ Choosing the smallest size for a wide plant room or busy production route.
Where this sign is not enough
❌ Do not rely on it where a specific hot surface symbol sign is required for touch hazards.
❌ Do not use it as the only control where guarding, insulation or PPE is needed.
❌ Do not fit vinyl to dusty, greasy, damp or flaking surfaces where adhesion may fail.
Better fitting choices for heat areas
✅ Place it before the approach point so people can change behaviour early.
✅ Use rigid plastic for rougher walls, outdoor areas or longer-term fixing.
✅ Check lighting, viewing angle and obstruction risk during routine safety inspections.
High Temperature Signs questions answered
What are High Temperature signs used for? They warn people that a hot process, room, machine or surface may create a burn, discomfort or unsafe-entry risk.
Should I choose rigid plastic or self-adhesive vinyl? Use rigid plastic where you need a stronger wall or door-mounted sign. Use vinyl on clean, smooth surfaces where adhesive fixing is more practical.
Where should this sign be fitted? Fit it before the hazard point, not after it. Good locations include plant room doors, boiler areas, ovens, heated machinery, process lines and workshop entrances.
Is W001 correct for this sign? W001 is the general warning symbol used with supporting text. Your supplied sign message explains the specific high temperature hazard clearly.
Do these signs replace risk controls? No. They support your heat risk controls by warning people early, but hot surfaces, guarding, training and safe systems of work still need managing.
