Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non- flammable, and non-toxic.Get price

Sulfr hexafluoride HANDLING PROCEDURE

f. The venting of Sulfr hexafluoride shall be minimized as much as possible. If discharge of small quantities is necessary for test purposes (i.e., contamination or moisture analysis, etc.), such discharge is to be kept to the minimum required to obtain a reading. 2.
