What is the minimum required radius for the display site?

The minimum required radius for the display site is critical for ensuring safety during a fireworks display. According to NFPA 1123, the required radius is based on various factors, including the type of fireworks being used and the potential hazards associated with the display.

The correct choice of 70 feet denotes the distance required to keep spectators and other nearby structures safe from the effects of the fireworks. This distance allows for adequate protection from debris, noise, and the potential for fire hazards that can occur when pyrotechnics are ignited. Establishing this safety perimeter is essential for protecting both the audience and property while ensuring that the display can be conducted in a controlled and secure environment.

In comparison to the other choices, such as 50 feet, 40 feet, and 25 feet, they do not meet the safety standards established by NFPA 1123. Insufficient distance could lead to severe safety risks, making it imperative to adhere to the 70-foot requirement to mitigate hazards effectively.
