What is a prerequisite for firing all pyrotechnic devices?

Firing all pyrotechnic devices requires them to be launched from specifically constructed equipment to ensure safety and control during the display. This equipment is designed to handle the unique pressures and temperatures generated by pyrotechnic devices, reducing the risk of accidents and ensuring proper function. Moreover, using appropriate equipment aligns with industry standards and regulations, enhancing the safety of both spectators and operators.

Other considerations, while important for the overall safety and legality of the event, do not serve as the prerequisite for firing devices. For example, being visible to the audience enhances the experience but does not directly impact safety or efficacy in firing. Approval by the Authority Having Jurisdiction (AHJ) is crucial for legal compliance but occurs prior to the actual firing process. Lastly, checking for malfunctions is a critical safety measure, but it is part of the preparatory steps rather than a condition for firing the devices themselves.
