What is required to be done with the electrical firing unit after the fireworks display?

After a fireworks display, it is essential to switch off and disconnect the electrical firing unit before proceeding with cleanup. This is critical for safety reasons. By disconnecting the system, you ensure that there are no accidental ignitions or electrical malfunctions that could occur if the system remains powered on. This precaution protects not only the crew involved in the cleanup but also the surrounding area from potential hazards.

Performing maintenance on or handling pyrotechnic equipment while it is still energized poses significant risks. Therefore, turning off and disconnecting the unit creates a safe environment for all personnel involved in the cleanup operation and minimizes the chances of unintentional ignition or accidents.

The requirement to power down the unit after the event aligns with best practices outlined in fire safety codes, underscoring the importance of caution and operational safety in handling fireworks and related equipment.
