Police across Berks County were on alert as Fourth of July fireworks celebrations got underway.
Authorities say they will be cracking down on residents using fireworks illegally.
In Reading, police officers have been giving handouts with a breakdown of what fireworks are only allowed to be used with a permit.
"For you to be able to handle them, you need to have the necessary licenses. So if you don't have those licenses, stay away from them," said Francis Acosta, city council president.
In 1998 six homes in the 100 block of Rose Street went up in flames due to careless use of illegal fireworks, fire officials confirm.
"When you play with fireworks, you're basically putting at risk probably your neighbors, your kids, your family, because they are a fire hazard," Acosta said.
In Reading, authorities say violators could face $1,000 fine and possible jail time.
They also say illegal fireworks will be confiscated and destroyed by the bomb squad.
