    Safe and efficient sf6 gas in circuit breakers South Africa,Properties of gaz sf6 (Sulfur Hexafuoride) GasHandling Nonfaulted gaz sf6Handling Faulted gaz sf6Disposal of Wastea) ToxicitySulfr hexafluoride is odorless, colorless, tasteless, and nontoxic in its pure state. It can, however, exclude oxy­gen and cause suffocation. If the normal oxygen content of air is re­duced from 21 percent to less than 13 percent, suffocation can occur without warning. Therefore, circuit breaker tanks shob) Toxicity Of Arc ProductsToxic decomposition products are formed when sf 6 gas is subjected to an elec­tric arc. The decomposition products are metal fluorides and form a white or tan powder. Toxic gases are also formed which have the characteristic odor of rotten eggs. Do not breathe the vapors remaining ic) Physical Propertiessf 6 is one of the heaviest known gases with a den­sity about five times the density of air under similar conditions. sf 6 shows little change in vapor pressure over a wide temperature range and is a soft gas in that it is more compressible dynamically than air.
