Maintenance sf6 pressure in circuit breaker Norway,Properties of sf 6 (Sulfur Hexafuoride) GasHandling Nonfaulted sf 6Handling Faulted sf 6Disposal of Wastea) Toxicitysf6 gas 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 Sulfr hexafluoride 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. sf6 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.
