Trafag sulfur hexafluoride pipes pdf

Sulfur hexafluoride meets all these essential requirements. Lester and Greenberg (813 showed SF6 to be completely safe by keeping rats in an 80 per- cent SF6 atmosphere for 24 hours with no ill effects. Sulfur hexafluoride is odorless, chemically and thermally stable, and is convenient to handle and dispense in air (13).
