No Smoking No Naked Lights Signs combine two clear prohibition messages to help you stop smoking, flames and open ignition sources where flammable materials, vapours or fuel may be present. They are useful for site managers, maintenance teams and visitors who need instant safety direction.

Where No Smoking No Naked Lights Signs Should Be Installed

You should install these signs at entrances to fuel stores, gas cylinder areas, workshops, chemical cupboards, plant rooms and loading points. Position them before anyone reaches the risk area so the smoking and flame restrictions are seen early, not after work has already started.

Viewing Distance Guidance For Choosing The Right Size

Choose the size around approach distance, doorway width and how quickly the message must be read. Smaller signs suit close-range doors and cabinets, while larger formats work better near yards, stores and busy access points.

Sign size	Practical viewing guide	Best use
H 100 x W 250 mm	Up to 3 metres	Cabinets, small doors, close-range checks
H 150 x W 300 mm	Up to 5 metres	Store entrances and internal walls
H 250 x W 350 mm	Up to 8 metres	Workshops, service areas and plant rooms
H 300 x W 500 mm	Up to 12 metres	Yards, fuel areas and wider approaches

What This Sign Helps You Control On Site

Once fitted in the right place, the sign helps you make ignition control visible before people enter a restricted area. It supports consistent behaviour from staff, contractors and visitors without relying on repeated verbal reminders.

✅ Reduces casual smoking near flammable substances

✅ Reinforces flame control before work begins

✅ Gives visitors clear rules at entry points

? Customers Questions

No Smoking No Naked Lights Signs questions answered

What are No Smoking No Naked Lights Signs used for? They are used to prohibit smoking and open flames where ignition could create a fire or explosion risk, such as fuel stores, chemical areas and plant rooms.

Do I need both symbols on one sign? Yes, when you want to control cigarettes and naked flames together. A combined sign gives one clear instruction instead of relying on two separate signs.

Which material should I choose? Use self-adhesive vinyl for clean, smooth indoor surfaces. Choose rigid plastic when you need a stronger sign for wall or door mounting.

Where should this sign be placed for best effect? Place it before the risk area, not inside it. Entrances, gates, fuel storage doors and workshop access points are usually the most effective positions.

Does the sign support compliance with recognised safety symbols? Yes. The smoking prohibition symbol aligns with EN ISO 7010 P002 and the open flame prohibition symbol aligns with EN ISO 7010 P003.

Compare flame-control signs with nearby prohibition messages

For sites that also need to stop food and drink, look at landscape smoking drinking and eating prohibition signs for broader conduct control. Useful in clean, restricted or hygiene-sensitive spaces.

If you prefer a vertical notice for doors or narrow fixing points, choose portrait no smoking drinking and eating signs where wall width is limited. They work well beside entrances and staff routes.

Where loose combustible items add risk, upgrade to no combustible materials no smoking signs for a fuller fire-prevention message. Helpful around storage, maintenance and handling areas.

For a cleaner two-message version, compare no smoking and no naked lights prohibition signs where you need straightforward instruction. Best for simple, repeated warnings at risk points.

To review the wider set, explore combined no smoking sign options and choose wording that fits the exact workplace risk. This helps avoid under-signing busy or mixed-use areas.
