Danger Explosive No Smoking No Naked Lights Signs combine explosive hazard warning with smoking and open-flame prohibition, helping you control ignition risks around stores, cabinets, workshops and restricted handling areas where one unsafe action could trigger a serious incident.

Where Danger Explosive No Smoking No Naked Lights Signs Should Be Displayed

You should install this sign at explosive material stores, cabinet doors, controlled room entrances, loading points and workshop access routes where people may carry cigarettes, lighters, matches or spark-producing items into a high-risk area.

H 300 x W 250mm	Doors, cabinets, cupboards, small rooms	Up to 5 metres / 16 feet
Multiple signs	Long approaches, shared access, busy stores	Repeat every 5–8 metres / 16–26 feet

? Customers Questions

Danger Explosive No Smoking No Naked Lights Signs questions answered

What are Danger Explosive No Smoking No Naked Lights Signs used for? They warn people that explosive materials may be present and that smoking, matches, lighters and other naked flames must be kept away from the area.

Where should I place this sign for the best effect? Fit it before the hazard point, such as on an explosive store door, cabinet, cupboard, controlled room entrance or approach route where people must change behaviour before entry.

Is this different from a standard no smoking sign? Yes. A standard no smoking sign only prohibits smoking, while this multi-message sign also warns about explosive danger and bans naked lights or open ignition sources.

Which material should I choose? Use self-adhesive Vinyl for clean, smooth indoor surfaces. Choose Rigid Plastic where you need a stronger sign for walls, doors, cupboards or more exposed workplace positions.

Does this sign show recognised safety symbols? Yes. It uses EN ISO 7010 W002 for explosive material, P002 for no smoking and P003 for no open flame, helping people understand the warning quickly.
