The Cosumnes CSD Fire Department is divided into two divisions, Operations and Administration & Support Services. These two divisions work in concert to provide leading emergency mitigation and fire prevention services in the region, all under the supervision of Fire Chief Tracey Hansen.
The Operations Division provides leadership and evaluation of assigned emergency personnel; responds to various emergencies dispatched throughout the community including fires, vehicle collisions, hazardous materials spills, medical and public assistance calls; and manages operation-based programs including emergency vehicle and equipment acquisition and management. Deputy Chief John Michelini leads the Operations Division with the assistance of seven Battalion Chiefs.
More than 150 sworn personnel work in the Operations Division, which has units devoted to Fire Suppression, Training, and Emergency Medical Services. The division staffs eight engine companies, one ladder truck company, six ambulances, and a command vehicle each day on a 24-hour basis. Additionally, there are eight grass engines and other specialty apparatus, including one heavy foam unit, a Heavy Rescue engine, a technical rescue trailer, a mass decontamination trailer, a mass casualty incident trailer, and a swift water rescue boat, also staffed using these personnel as seasons and emergency circumstances dictate.
