Maintenance sf6 breaker gas pressure Pakistan,Properties of sf6 gas (Sulfur Hexafuoride) GasHandling Nonfaulted sf 6Handling Faulted Sulfr hexafluorideDisposal of Wastea) Toxicitygaz sf6 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 sf6 gas 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.
