LAKEWOOD, Colo. -- Firefighters throughout the metro area have been on patrol looking for people with illegal fireworks.

Most fireworks have been banned because of high fire conditions and dangers involved with using them.

Police issued tickets to people who were caught with fireworks. Firefighters with West Metro fire expected to issue about 100 tickets Monday and Tuesday. Nearly all fireworks are banned in Jefferson county, although people can still buy fireworks that make noise but don't ignite.

Some people told 7NEWS they didn't understand why fireworks like sparklers are banned this year.

"I don't see how that could be harmful really. With little kids, if their parents are watching them in their front yards having fun," said Bo Boatright. "I don't see a problem with that."

Fire officials said even seemingly harmless fireworks like sparklers and spinners can burn at incredibly high temperatures and have started fires in Jefferson county.

"The laws are in place to protect homes and prevent injury. People think you're pooh-poohing on the Fourth of July but that's not it at all," said Cindy Matthews of West Denver fire.

The penalty for being caught with fireworks could be up to a $1,000 fine and up to six months in jail.

"In about two weeks they'll have to take time off work, appear before a judge, plead their case, so it's a lengthy process and it just isn't worth it," said Matthews.
