Sulfur hexafluoride (SF6) was taken as inert gas in pharmacology. But once contained with SF4,it will be toxic. If people inhalt with high concentration SF6, they will have a series of suffocation symptom,such as difficult to breath , skin and mucous membrane turning to blue and general convulsive seizure.


.Safety Gas container can be leak hunting by soap water. SF6 is non-corrosiveness ,hence it can be contained by stainless,copper,aluminium. Once on fire, it is okay to put off by water and sand. Mixture water with sodium hydroxide and slaked lime can deal with leak gas or just put the leak container into exhaust locker.
