AUDIO: Gibraltar Fire Chief Jerrad Anderson has been a busy man since taking over for Caleb Whitney, who resigned from the post in February. In addition to running the volunteer department, the former department captain Anderson has been trying to grow his firefighter numbers and replace equipment on Chambers Island. Anderson says the new equipment and a certification program for island residents will make responding to emergencies there more effective. The Gibraltar Fire Department will host an open house this Saturday beginning at 10 a.m. and will feature equipment demonstrations, apparatus displays, and kids’ games.
