Sulfur hexafluoride SF6 gas hazards. Sulfur hexafluoride (SF6) is colorless, odorless, heavier than air and is not considered as toxic.However it is suffocating at high concentrations (it replaces oxygen) just like inert gases (also called noble gases). Sulfur hexafluoride has no lower and upper explosive limits but can severely react with disilane and form a dangerous explosive gas mixture.

Get PriceAlternativesReconditioningTrainingConclusionReferencesSome proposed alternatives fall short of SF6 and would create an enormous economic burden on utilities because it would require a complete overhaul of their gas insulated switchgear (GIS) equipment. We make the case that the industry has an SF6 handling problem, not an SF6problem. The industry could make two changes to drastically decrease SF6emissions: 1. Use reconditioned SF6 instead of importing virgin gas. 2. Ensure that trained and certified personnel are using best management and safety practices when handling SF6. The United States has a large stockpile of SF6 gas. From an environmental perspective, reconditioning gas could lower the carbon footprint by removing the need to manufacture new product. Sulfur hexafluoride is 100 percent recyclable, and there is no chemical difference between virgin SF6 gas and certified reconditioned SF6gas. Any contaminants that occur due to the intrusion of air, moisture, or generation of arc by-products can be removed with the proper process.See more on netaworldjournal.orgSF6 Gas Characteristics | our company Company us.our company/sf6-gas/useful-information-sf6/propertiesSF6 gas (Sulfur hexafluoride) characteristics: colorless, odorless, heat resistant, chemically stable, non-toxic.
