Get PriceSulfur 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 PriceSF 6 Free Gas Handling Alternatives to SF 6. The so-called "Alternative Gases" are alternatives to SF 6, the preferred insulating and arc-quenching gas used in switchgear in the last few decades.While SF 6 has excellent dielectric properties, it is also the most potent greenhouse gas with a GWP of 23,900. Ideally, SF 6 should be used in closed loop systems and never be emitted into the atmosphere.
