Fourth of July barbecues and fireworks go hand in hand.

But the wrong fireworks could result in an unexpected guest at your party - the local police.Departments in Carbon County are on the lookout for illegal fireworks. But they said that revelers who set off fireworks responsibly, and don't anger their neighbors, should be able to enjoy the night without a visit from police."The goal is just to make sure everybody is being safe. A lot of people get injured by fireworks," Chief Audie Mertz of Mahoning Township Police Department said.The state's fireworks law limits what residents can purchase. The law does not regulate the purchase of "novelty fireworks" such as sparklers and ground-based devices. Anything more, residents need a permit issued by their local municipality to buy the fireworks.But fireworks purchased out of state are a gray area, as many amateur pyros know. Police admit that if they get a call about fireworks, there is not much they can do under state law."The way (state law) reads is that you can't buy them," Brian Markovchick, Weatherly Borough Police Chief, said. "It's pretty convoluted. Our guys use common sense and determine if it's going to be a problem at that time."But that shouldn't be construed to mean that police are powerless against illegal fireworks. Markovchick said there are a number of ways that irresponsible fireworks can violate the law. Damage to a property could result in criminal mischief or reckless burning violations.And the most obvious violation associated with fireworks has to do with noise. Mertz and Markovchick said the number of complaints in their municipalities is low, but there will undoubtedly be one or two this year on the Fourth."When we get noise complaints, we do investigate them as long as we have available officers," Mertz said. "Just make sure that you're being cautious, and whatever you're using is a legal firework."
