What is the maximum size for single-break aerial salute shells?

The correct maximum size for single-break aerial salute shells, as outlined in NFPA 1123, is 5 inches in diameter. This size limitation is established to ensure safety during operations, as larger shells may present greater risks of malfunction or debris falling within the spectator area. By maintaining a maximum size of 5 inches, the Code aims to minimize potential hazards while still allowing for a visually impressive display. Understanding these limitations helps ensure that all safety protocols are followed during fireworks displays to protect both the personnel involved and the audience.
