One at a time please:

You (or another adult that you choose) must be the only person letting off fireworks. Don't allow anyone else - especially children - to do so while your display is going on. Let the fireworks off one at a time (not lots at once) and don't rush. Light the tip of each firework at arm's length, using fireworks lighter or fuse wick. Stand well back immediately. If one doesn't go off, don't go back to it - it could still be live, and could go off unexpectedly on your face. Right at the end of your fireworks night, douse the 'duds' with lots of water, keep it soaking in a bucket of water. Never throw left over fireworks onto a bonfire.
