Asbestos Risks on the USS Chester T. O'Brien (DE-421)

The USS Chester T. O'Brien (DE-421) was a destroyer escort mainly designed for anti-submarine and anti-aircraft battle during World War II. This ship was built during the time when the use of asbestos in shipbuilding was rampant, and as a result, most of the equipment on this ship contained asbestos. Boilers, pumps, pipes, valves, turbines, electrical fixtures, hull construction, and other propulsion equipment often had asbestos insulation thereby exposing several sailors serving on the USS Chester T. O'Brien (DE-421) and people involved in the building, renovation, repair, and demolition of the ship. Asbestos was also used as a fire retardant in most places within the ship, for instance, the non-skid flooring on the decks and on bulkhead walls. Consequently, Navy veterans, as well as personnel such as boiler tenders, machinist mates, electrician's mates, pipefitters, shipbuilders, and shipyard workers, are at an increased risk of developing asbestos-related diseases including malignant mesothelioma, lung cancer, and asbestosis.
