Use fireworks outdoors only on a hard, flat and level surface to insure stability.

Obey local laws. If fireworks are not legal where you live, do not use them.

Always have water handy. (A hose or bucket).

Only use fireworks as intended. Don't try to alter or combine them.

Never relight a "dud" firework. Wait 20 minutes and then soak it in a bucket of water.

Use common sense. Spectators should keep a safe distance from the shooter and the shooter should wear safety glasses.

Alcohol and fireworks do not mix. Have a "designated shooter"

Only persons over the age of 16 should be allowed to handle sparklers of any type.

Do not ever use homemade fireworks or illegal explosives: they can kill you! Report illegal explosives to the fire or police department in your community.

Never aim, point, throw, or shoot fireworks at another person.

Always store fireworks in a cool, dry place and dispose of properly.
