What is the minimum height requirement for an airburst effect when fired above the audience?

The minimum height requirement for an airburst effect when fired above the audience is established as three times the diameter of the effect. This guideline is crucial for ensuring safety during a performance, as it helps to mitigate potential hazards associated with debris or fragments that can occur when fireworks detonate or burst in the air.

Having this height requirement means that there is sufficient distance between the audience and the point where the firework explodes. By following the guideline of three times the diameter, operators can effectively reduce the risk of injury and ensure that the audience is at a safe distance from any fallout from the aerial explosion. This standard aligns with safety protocols intended to protect everyone present during a fireworks display, emphasizing the importance of adequate spacing in pyrotechnics to prevent accidents and maintain a safe viewing environment.
