No Smoking prohibition sign

The image features a standard international 'No Smoking' prohibition sign. This symbol is part of the ISO 7010 standard, which specifies safety signs for the purposes of accident prevention, fire protection, health hazard information, and emergency evacuation.

Because this symbol is a universal design rather than a consumer product from a specific brand, it is produced by thousands of independent signage manufacturers worldwide. These signs are used globally in public spaces, workplaces, and private transport to enforce smoke-free laws and safety regulations. There is no single brand or company that claims exclusive ownership of this icon as it is a public safety standard.
