Which statement correctly lists THAAD safety distances?

• A. 50 m personnel zone, 200 m safety fan, 100 m backblast
• B. 100 m personnel zone, 500 m safety fan, 300 m backblast
• C. 200 m personnel zone, 600 m safety fan, 400 m backblast
• D. 150 m personnel zone, 450 m safety fan, 350 m backblast

Answer: (B)

THAAD safety distances are three hazard radii around the launcher: the immediate personnel zone, the forward safety fan, and the backblast area behind the launcher. The goal is to keep people and sensitive assets clear of any dangers from launch, intercept, or backblast events. The forward safety fan is the largest because debris and fragments can travel outward in front of the launcher during firing and intercepts, so a wide exclusion zone is needed there. The backblast distance sits behind the launcher at a moderate size to protect personnel and property from the blast effects, heat, and pressure, while the personnel zone around the launcher remains the smallest for close-in safety and control of the immediate area. The numbers that align with standard THAAD safety planning are a 100 m personnel zone, a 500 m forward safety fan, and a 300 m backblast. This combination reflects the practical hazard distribution for THAAD operations. The other options propose zones that are too small or not balanced with the typical forward-versus-back hazard pattern, which would not meet safety requirements.
