No Entry Sign - Unauthorized Access Prohibited Symbol #159543 (License: Personal Use)

The image displays a standardized prohibition sign: a red circle with a diagonal slash (implied by the border) enclosing a black pictogram of a human figure stepping through an open doorway. This visual cue universally communicates that entry is forbidden, often due to safety hazards, security protocols, or legal restrictions. The clean, high-contrast design ensures immediate recognition across language barriers.

Used on safety signage in workplaces, construction sites, restricted zones, and public infrastructure to prevent accidents or breaches. Matches user intent for understanding warning symbols, compliance training, or designing safety materials.
