According to a Phoenix Fire Department news release, most fireworks injuries involve children. Many of the burn injuries are associated with the firework firing early, possibly causing disfiguring burns to the hands and eyes.
Most fires from fireworks occur in dry brush and grass, but homes are also vulnerable on July 4. Many of these fires are caused by careless handling of fireworks, even though though most are illegal in the City of Phoenix.
"Use or possession of fireworks is a Class 1 misdemeanor with a fine of up to $2,500 and/or six months in jail. Only licensed vendors are allowed 'controlled' fireworks displays.
