No Exit Sign - Official Prohibition Symbol for Safety Compliance #1395731 (License: Personal Use)

This image displays a standardized safety sign featuring a bold red rectangle with "NO EXIT" in large, white, uppercase sans-serif letters. Above the text is a red circle with a diagonal slash-the universal prohibition symbol-indicating that the area beyond is not an exit route. The design follows OSHA and ISO standards for visibility and immediate recognition in emergency situations.

Used in commercial buildings, industrial facilities, and public spaces to mark non-exit doors during fire drills or evacuations; supports compliance with fire codes and reduces confusion during emergencies.
