But just because it is legal, doesn't mean it is safe. When buying fireworks, make sure to use them in the method the manufacturer recommends. Sparks are still hot, so make sure there is no fuel underneath it. It's recommended you light it on a parking lot surface instead of in your backyard to prevent accidental ignition. Remember: All big fires start as small fires.
