If a firework fails to light or stops
If a firework fails to light, or stops unexpectedly, keep everyone away from the firework and do not attempt to relight it, unless the manufacturer’s instructions specifically describe using a supplied reserve fuse. Follow that procedure exactly. If unsure, leave the firework and contact the retailer. Use a supplied reserve fuse only if the manufacturer’s instructions permit it. Wait at least 15 minutes and any longer time stated on the label, then follow the full procedure. Never relight the original fuse or attempt a repair. If there is no permitted reserve-fuse procedure, keep everyone away and contact the retailer the following morning.
