What does a No Entry Zone indicate?

• A. Nobody is allowed to enter this zone — Red with white chevron
• B. Entry is allowed with PPE
• C. Open for public access
• D. Restricted to incident commanders

Answer: (A)

A No Entry Zone means entry is strictly prohibited because of hazardous conditions. The zone is marked with red and a white chevron, which is the clear visual signal that crossing the boundary is not allowed. This protection is in place to keep people out unless there is explicit authorization and the proper safety procedures are in place, since hazards in that area could endanger anyone who enters. PPE or other gear cannot automatically make entry permissible here—the prohibition stands until a formal exception is granted. It isn’t open to the public, and it isn’t limited to incident commanders; access is restricted to authorized personnel under controlled conditions.
