What is a No Smoking Sign?

A no-smoking sign is a visual communication tool used to indicate that smoking is prohibited in a specific area or setting. These signs are designed to promote public health, protect individuals from secondhand smoke, and prevent fire hazards.

Purpose of No Smoking Signs

No smoking signs serve several important purposes in promoting a smoke-free environment:

  1. Clearly Indicate Smoking Prohibition: No smoking signs provide clear and unmistakable instructions that smoking is not allowed in the designated area.
  2. Protect Public Health: By prohibiting smoking, that may include banning e-cigarettes, in public spaces, these signs help to reduce the exposure of non-smokers to secondhand smoke, which is a known health hazard.
  3. Prevent Fire Hazards: Smoking materials can pose a significant fire risk, and no smoking signs help to minimize this risk by prohibiting smoking in areas where combustible materials may be present.
  4. Promote Social Norms: No smoking signs contribute to establishing social norms that discourage smoking in public spaces, making it less acceptable and socially acceptable to smoke in these settings.

Design and Symbolism of No Smoking Signs

No smoking signs are typically characterized by their red circle with a diagonal slash through a black cigarette and smoke symbol. This standardized design is easily recognizable worldwide and clearly conveys the message that smoking is prohibited.

In some instances, no smoking signs may also include text descriptions or additional symbols to reinforce the prohibition, such as phrases like "No Smoking" or "Smoking Prohibited." These additional elements can be helpful in cases where language barriers may exist or when further clarification is needed.

Placement of No Smoking Signs

No smoking signs should be strategically placed in visible locations throughout the designated smoke-free area. They should be positioned at entrances, exits, along walls, and in areas where smoking is particularly likely to occur. No smoking signage should be mounted at a height that is easily seen by occupants, typically between 6 feet and 8 feet from the floor.

Compliance with Regulations

No smoking signs must comply with relevant regulations, such as the Smokefree (England) Regulations 2007 in the UK. These regulations specify the requirements for displaying no smoking signs in public places, ensuring consistency and effectiveness in promoting smoke-free environments.


No smoking signs play a crucial role in promoting public health, preventing fire hazards, and establishing social norms that discourage smoking in public spaces. By clearly indicating smoking prohibitions, these signs help to protect individuals from secondhand smoke and contribute to a healthier and safer environment for all.
