When should the safety cap protecting the fuse of fireworks be removed?

The safety cap protecting the fuse of fireworks should be removed immediately before the shell is to be fired by the shooter. This practice is essential because it minimizes the risk of accidental ignition or premature firing of the fireworks. By keeping the safety cap on until just before firing, crews can ensure that the fireworks remain safe and secure during transport and setup, thus preventing any unintentional activation.

This timing also allows the shooter to assess the firing line and ensure the area is clear of any personnel or obstacles, creating a safer environment for the display. It's critical that this step is coordinated with all individuals involved in the firing process to maintain safety protocols and adhere to NFPA 1123 standards.

In contrast, removing the cap at other times, such as before the display starts or after the event, could lead to dangerous situations and goes against the recommended safety practices outlined in the NFPA guidelines.
