Before you light any fireworks, make sure that you have a water source on hand. Fill a couple of buckets with water to dunk used fireworks and put out fires. Keep a hose or a fire extinguisher nearby. In a pinch, you can pour a bucket of soil or sand over a fire to extinguish the blaze – but water will be most effective.;
, Submerge them in a large bucket of water until they are thoroughly cooled and all of the embers have been extinguished. Soak for at least fifteen minutes, and soak overnight if possible. This applies to all spent fireworks, "dud" fireworks, and sparklers.


For extra safety, soak the fireworks from a distance. Pour water from a bucket, or spray the explosives using a garden hose.
It's important to soak even the fireworks that don't go off. Sometimes, "duds" explode late, causing fire or injury. Never try to relight a "dud" – wait 20 minutes after the failed detonation, and then soak the explosive in water.
Remove the fuse from live fireworks. If you are trying to dispose of fireworks that have not yet been lit, make sure to pull off the wicks so that the explosives won't detonate.
 The compounds that are used to make the colorful explosions contain metals that can pollute the air, water, and surrounding ecosystem. Furthermore: if you set off fireworks near the surface of a body of water, the concussion can kill fish and other local wildlife. If your fireworks do explode above a body of water, make sure to promptly remove any visible debris from he explosive shell.
Prepare a water source.
Dunk fireworks in water after use.
Do not soak fireworks in or near a natural body of water.
