To dispose of firearms, gunpowder and ammunition, contact your local police department or the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) Harrisburg Field Office at 717-231-3400.
To dispose of flares, contact your local fire department.
Before disposing of used or unused fireworks, they must be soaked in water in a metal container for several days. After soaking, place the wet fireworks into a sealable plastic bag which reduces the chances of them drying out and becoming explosive again, and place in the regular trash. Never place fireworks in the trash before following the aforementioned steps. Click here for more information on fireworks management from the Pennsylvania Office of Emergency Management.
