The St. Clair County Sheriff's Office says a 22-year old Almont Firefighter was injured Thursday night while responding to assist Berlin Township.  Sheriff Tim Donnellon says David Gaj was driving a tanker truck on Almont Road shortly after 8:30pm.  As he approached Capac Road and tried to turn, he lost control on loose gravel and rolled into a ditch.  He was taken to a hospital with non-life threatening injuries.
