Sign. 'No smoking' sign. Smoking is prohibited either for safety reasons or for health reasons. It is unsafe to permit smoking in areas where there are,or potentially are,flammable materials. Exposure to 'passive smoking' can cause health effects in a non-smoker similar to those seen in smokers. Photographed at a London Underground station | |
