Question: There have been stories in recent days about unexploded fireworks being found in fields several days after Fourth of July fireworks displays in Wilmington and Stoughton and other towns. Are we sure there aren't any unexploded fireworks down on Livingston Street? After all, kids play down there.

Answer: The short answer to this question is no, there are not. But the longer answer is, the Tewksbury Fire Department has policies in place to make sure there are not -- ever.

According to Fire Chief Mike Hazel, the day after every fireworks display, a representative from the fireworks company (in this case, Atlas Fireworks) does a walk through of the shooting site with a command officer from the Fire Department.

"It's a condition of the permit," said Hazel. "One of the conditions is that the 'shooter' do a first-light inspection of the site with the captain on duty."

This week, the State Fire Marshal's office suspended the license of Pennsylvania-based Pyrotecnico, which staged displays in several Massachusetts towns this July, including Newton, Milford, Hingham, Winchester, Westford, Sharon, Waltham, Ayer, Marion, Waltham, Stoughton and Wilmington.

Recently, unexploded fireworks shells had been found in Wilmington, Waltham and Stoughton. In the Waltham incident, a city worker ran over the shell with a lawn mower, causing it to explode. Fortunately, he was not injured.
