Investigation of a High Pressure Oxygen Fire in the Recompression Chamber System at the Fleet Diving Unit, Pacific.

Abstract : A fire in the piping system of the high pressure oxygen side of the recompression chamber at the Fleet Diving Unit, Pacific has led DREP to undertake a comprehensive look at the cleaning procedures and the materials used in an oxygen environment. As a result of this investigation, it was established that Teflon and Viton coated with Krytox, (a fluorosilicone grease) could be used in a high pressure oxygen system. A cleaning procedure for parts used in oxygen service is also included. (Author)
