The law requires you to stay 150 feet away from any occupied building when using fireworks.
If a Roman candle or bottle rocket doesn't go off properly, Trego advises to stray on the cautious side.
"I would recommend you never try to relight the dud, the one that didn't go off," he said.
When disposing of fireworks, Trego said wait until they're cool, then soak them overnight in a bucket of water.
"Soak them with water, and do not dispose of them in a burn barrel or somewhere where it's close to heat," he said.
It's best to wrap the fireworks in a plastic bag to keep them from drying out, and then put them outdoors in your regular household garbage.
But before you seek out these fireworks, check with your town's ordinance. They may be legal in the state, but not your neighborhood.
According to the Pennsylvania Office of the State Fire Commissioner, eight amateur fireworks lighters died in 2017, while nearly 13,000 people were treated in emergency rooms nationwide for fireworks-related injuries. Thirty-six percent of those injuries were among children under the age of 15.
