Ground display pieces shall have a minimum display radius of how many feet?

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

Answer: (B)

Ground display pieces need a safety buffer around the device because their effects spread across the ground toward the audience. A minimum display radius of 75 feet creates a reliable circle of space so spectators and nonessential staff stay far enough away from sparks, embers, and any misdirected flames. This distance is chosen to balance safety with practicality for most venues, ensuring a consistent standard that reduces risk during displays. A smaller radius wouldn’t provide adequate clearance, while a larger radius is more conservative than required by the standard.
