Smoking area signs are signs that indicate designated smoking areas. These signs are important for maintaining safety in workplaces and public areas by ensuring that smokers are smoking in designated areas and not in areas where it could pose a fire risk or be harmful to non-smokers. 

Smoking area signs can come in various designs and formats, including wall signs, post signs, and floor signs. They typically feature the universal no-smoking symbol with an indication that smoking is only allowed in the designated area. In some cases, they may also include additional information such as any restrictions or rules that apply to the smoking area. 

It is important to ensure that smoking area signs are clearly visible and located in appropriate areas to prevent confusion and promote compliance with smoking regulations.
