Dive Team
Established in 1986, the C-O-MM Fire Department Underwater Search team is the oldest continually operating public safety dive unit in Barnstable County. Currently, the Team is comprised of 17 department members including 10 divers and 7 support tenders. The Team trains twelve months per year in all types of weather conditions, including sub-ice, in various water bodies within the district and surrounding region.
The Team utilizes fully encapsulated diving systems including full facemasks and dry suits, to protect from cold exposure and hazardous materials such as body fluids and fuel. The majority of diving evolutions are in low to no visibility due to the mud and silt conditions found in most lakes, ponds, bays and rivers. Tenders direct diving search patterns through wireless communication systems, as well as a tether-based communications language using line pull signals.
The unit is activated for all reports of missing swimmers, persons through the ice, and boating accidents with reports of persons in the water. It has made many victim recoveries from drownings due to swimming and boating casualties, jumping accidents, and sunken vessel entrapment. The team also works closely with the Town of Barnstable Harbormaster’s Office, and Barnstable Police Department.
Marine Units
The department operates four vessels covering the adjacent waters of Nantucket Sound as well as the district’s bays, rivers, estuaries, lakes and ponds.
