What is a requirement for holders of pyrotechnic devices?

The requirement for holders of pyrotechnic devices to remain in a fixed position when fired is essential for safety and effectiveness. This ensures that the pyrotechnic device is stable during ignition and throughout the display. When the holder is fixed in place, it reduces the risk of the device tipping over or being displaced, which can lead to unintended firing or accidents.

Stability is crucial for controlling the direction and height of the effects produced, as well as for safeguarding both the operators and the audience. Properly designed holders prevent movement that could alter the trajectory or timing of the fireworks display, thereby ensuring a more reliable performance.

In contrast, a holder constructed to be portable might introduce risks if not secured properly, while the use of any material may compromise safety or durability. Adjustable holders during firing could also create hazards. The fixed position requirement helps maintain a controlled environment for the execution of pyrotechnic effects.
