No Entry Sign - Authorised Personnel Only Warning Symbol #2217665 (License: Personal Use)

This high-contrast safety sign features a red circular border with a diagonal slash over a black silhouette of a walking person, universally recognised as a prohibition symbol. Below the graphic, bold uppercase text states “NO ENTRY AUTHORISED PERSONNEL ONLY” to reinforce access restrictions. The design follows ISO 7010 standards for clarity and immediate recognition in industrial, commercial, or secure facilities.

Used at restricted zones such as construction sites, data centers, military bases, or private property entrances to deter unauthorised access and support legal liability protection. Matches user intent for safety signage procurement, regulatory compliance guidance, or facility management resources.
