The image displays the standard no smoking symbol-a black cigarette with rising smoke inside a white circle, overlaid with a bold red diagonal slash and encircled by a red border. Designed for high visibility and instant recognition, it complies with ISO 7010 and OSHA standards for safety signage. It is commonly deployed in public buildings, transportation hubs, workplaces, and outdoor spaces to enforce smoke-free policies.

Used on websites, signage, policy documents, and public health campaigns to communicate smoking restrictions; matches user intent for understanding regulations, compliance guidance, or visual communication of禁烟 zones.
