ABSTRACT
This study reports two occupational deaths resulting from exposure to fluorocarbon-113 (1,1,2-trichloro-1,2,2-trifluoroethane; FC-113) in enclosed and confined spaces. One incident involved a worker who was exposed to FC-113 after entering a small degreasing tank to clean it. The second case involved a significant spill of FC-113 onboard a marine vessel. The incidents are compared to other fatal exposures.
