More fires are reported on July 4 than any other day of the year; fireworks also cause many serious injuries each July

With the Fourth of July approaching, the Sheriff's Bomb/Arson Unit reminds San Diegans that it's illegal to possess and use fireworks in the county. It's also illegal to transport fireworks from elsewhere into San Diego County or to make homemade fireworks or explosives.

Under California law, illegal fireworks include sky rockets, bottle rockets, roman candles, aerial shells, firecrackers and other items that explode, go up in the air, or move across the ground in an uncontrollable fashion. Those convicted can be fined up to $50,000 and sent to prison or jail for up to one year.
