It can, however, exclude oxy­gen and cause suffocation. Ib) Toxicity Of Arc ProductsToxic decomposition products are formed when SF6 gas is subjected to an elec­tric arc. The decomposition products are mec) Physical PropertiesSF6 is one of the heaviest known gases with a den­sity about five times the density of air under similar conditions.
