Who oversees the activities of an Assistant in fireworks displays?

The activities of an Assistant during fireworks displays are overseen by the pyrotechnic operator. This is because the pyrotechnic operator is responsible for the overall execution of the display, including safety measures, adherence to regulations, and the handling of explosives. The operator has the technical expertise and authority to direct the actions of the assistants, ensuring that all activities are carried out in accordance with established safety protocols and procedures outlined in NFPA 1123. This direct supervision is crucial for maintaining a safe environment during the event and for effectively responding to any unforeseen issues that may arise.

While the fire safety officer plays a critical role in fire-related safety measures at an event, and the event organizer manages logistics and planning, it is the pyrotechnic operator who directly guides the assistants in their specific roles, making this choice the most suitable answer. Additionally, regulatory agencies may set standards and guidelines, but they do not oversee the day-to-day operational activities of assistants on the ground during a fireworks display.
