What must be prominently displayed in smoking areas?

The requirement for smoking areas to prominently display smoking area signs serves a crucial purpose in promoting safety and awareness. These signs clearly indicate designated zones where smoking is permitted, helping to prevent confusion among individuals in the vicinity regarding where smoking is allowed. By providing a visual cue, these signs help protect non-smoking individuals from exposure to secondhand smoke and ensure that the smoking activity is contained within specific, sanctioned areas.

In contrast, no smoking signs, lit cigarette warnings, and hazard labels may not effectively communicate the designated nature of smoking zones. While they play important roles in regulating non-smoking areas and indicating potential dangers, they do not serve the express function of marking an area where smoking is accepted. Thus, clear signage identifying a smoking area is essential for both public health and compliance with smoking regulations.
