Increase safety and avoid explosions and fires in hazardous areas by prohibiting open flames. These signs inform the public that there is a ban on smoking and open flames on the premises.

The sign meets the requirements of the European standard EN ISO 7010. The standard determines the design and colour of safety signs in workplaces and in other locations where people need safety information. The aim is for the safety signs to be easy for anyone to recognise and understand regardless of where they are and which language they speak.
