We like to think that fireworks are like a good meal and making sure you are prepped correctly makes it so much better and easier.
We recommend that on the day of firing you have a look at your fireworks, remove them from their boxes and lay them out, you should then work out what order you will be firing them in. Once this is decided we suggest you give yourself adequate time (depending on the number of fireworks you have) to lay them out and secure them properly prior to firing.
We are now going to lay the fireworks out, and we like to do this in a snake formation, for example, if you have 15 fireworks create three rows of 5 starting from left to right 1-5 and then come backwards on yourself (see diagram below), this ensures you are always working away from the previous, spent firework ensuring firing as safely as possible. You can watch a video demo here. (please note this is an old pack, it is simply to give you an idea)
