To calculate how much space you need in your garden to set off F2 fireworks you need to know the length of your garden at its longest point. You’ll need to ensure all spectators can be at least eight metres away from the firework launch site, or 15 metres if that’s what the product specifies. You’ll also need to make sure that the position of the firework isn’t in the firing line of any objects, such as trees, that could cause a fire. Depending on the number of guests viewing your fireworks you might need to account for 1-2 metres extra so that everyone can safely stand away from the firework. A garden of roughly 10 metres in length is ideal for 8-metre F2 fireworks.
