In hazard marking, lighting and signing, which group must be prevented from entering areas open to aircraft?

• A. Pilots.
• B. Construction personnel.
• C. Airport maintenance staff.
• D. Passengers.

Answer: (B)

Hazard marking, lighting, and signing are used to designate areas where entry is controlled to protect people and aircraft from movement and operational hazards. Construction personnel must be kept out of areas open to aircraft because their work introduces temporary and unpredictable dangers—moving heavy equipment, trenches, loose materials, debris, and altered surfaces—that can cause injury or interfere with aircraft operations. These zones require authorized, trained personnel who understand the risks and follow established safety controls. Pilots and airport maintenance staff operate under controlled conditions and would access designated areas with proper authorization and supervision, while passengers are kept out for safety. Thus construction personnel are the group that must be prevented from entering areas open to aircraft.
