Smoking is Not Permitted on These Premises - Safety Signs
Smoking is Not Permitted on These Premises Sign
No Smoking Signs are required in Workplaces, Public Buildings and certain Vehicles. You need to display ‘no smoking signs’ in a prominent position at each entrance to ‘smoke free premises’. (These no smoking signs should be a minimum of A5 in size). The no smoking signs should contain the words “It is against the law to smoke in these premises”.
You can also use supplementary smaller no smoking signs within a building. These no smoking signs only need the international no-smoking symbol (just the image of a burning cigarette enclosed in a red circle).
