What is the minimum display radius for ground displays?

• A. 50 feet
• B. 75 feet
• C. 60 feet
• D. 100 feet

Answer: (B)

Ground displays carry the risk of sparks, embers, and debris reaching spectators, even when effects are aimed at the ground. Setting a safe, minimum radius creates a clear buffer zone around the device so that bystanders stay far enough away to avoid injury in case of misfires or excessive projection of material. The established minimum for ground displays is 75 feet, which provides that protective margin between the display and the audience. Distances like 50, 60, or 100 feet do not align with this standard minimum, though actual requirements can vary with circumstances and local regulations.
