Maintenance sf 6 circuit breaker Mexico,Properties of sf 6 (Sulfur Hexafuoride) GasHandling Nonfaulted sf6 gasHandling Faulted gaz sf6Disposal of Wastea) Toxicitysf 6 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 PropertiesSulfr hexafluoride is one of the heaviest known gases with a density about five times the density of air under similar conditions. insulating gas 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.
