Prohibition Symbol - Universal "No" Sign for Safety and Restrictions #79719 (License: Personal Use)

This high-contrast red prohibition symbol features a thick diagonal line crossing through a solid red circle, set against a black background for maximum visibility. Designed for instant recognition, it conveys “forbidden,” “prohibited,” or “not allowed” in contexts ranging from traffic control to workplace safety and digital interfaces. Its standardized form follows ISO 7010 and ANSI Z535 guidelines for hazard communication.

Commonly used on safety signage, warning labels, user interfaces (e.g., disabled buttons), and regulatory documentation to communicate restrictions. Matches user intent for understanding prohibitions, compliance requirements, or visual cues in risk management.
