No Entry Sign with Hard Hat - Safety Warning Symbol #17123 (License: Personal Use)

The image displays a standard prohibition symbol: a red circle with a diagonal slash over a black open hand gesture, halting a line-art figure wearing a hard hat. The stark contrast of red, black, and white ensures high visibility and immediate recognition in industrial, construction, or restricted facility settings. It communicates strict access control and compliance with occupational safety regulations.

Commonly used on construction sites, factory entrances, utility rooms, or secure facilities to warn against unauthorized entry; matches user intent for safety signage, OSHA compliance resources, or hazard communication training materials.
