  • MANAGEMENT AND SAFE HANDLING PROCEDURES

    Bureau of Reclamation (Reclamation) facilities have more than 1,000 power circuit breakers; the most modern of them use sulfur hexafluoride (SF6) gas as an arc-interrupting/quenching and insulating agent. Breakers of this design are now the standard; for some applications, they are the only power circuit breakers available in the industry.
