  • MANAGEMENT AND SAFE HANDLING - Bureau of

    Bureau of Reclamation facilities have many circuit breakers containing SF6 gas as an insulating medium. SF6 has been identified as a greenhouse gas that may be responsible for global warming. Release of SF6 gas into the atmosphere during maintenance work or an accident must be reduced, tracked, and reported to the EPA.
