What primary responsibility does a loader have during a fireworks display?

The primary responsibility of a loader during a fireworks display is to load aerial shells into mortars. This task is critical because the loader ensures that the shells are securely placed in the mortars and positioned correctly for firing. Proper loading is essential for the safety and success of the display, as it affects how the fireworks will launch and perform once ignited. The loader must also be knowledgeable about the types of shells being used and adhere to safety protocols to prevent accidents during the loading process. This role requires attention to detail and an understanding of the equipment and materials involved in the fireworks display.
