| Comments |
". . . it seems unlikely that a gas as inert as sulfur hexafluoride would exert any toxic effect in concentrations as low as 1000 ppm. The chief hazard, as with other inert gases, would seem to be asphyxiation as a result of the displacement of air by this heavy gas." [ACGIH] Possible frostbite from contact with liquid; [NIOSH] |
