What is required for electric matches that are attached to display fireworks?

Electric matches, or e-matches, used in fireworks displays are critical components in ensuring safety and functionality during a show. One of the essential safety requirements is that electric matches must have a shroud protecting the match head. This protection is vital as it minimizes the risk of accidental ignition caused by exposure to static electricity, stray currents, or other unintended stimuli. The shroud serves to physically cover the sensitive components of the electric match, thereby increasing safety for the operators handling the fireworks and helping to maintain control over the ignition process.

The careful management and protection of electric matches are crucial in professional fireworks displays, as they ensure that ignition is only initiated under intended conditions. This practice is consistent with the guidelines set forth in the NFPA 1123 code, which emphasizes the importance of safety equipment and procedures when dealing with pyrotechnics.
