SF6 gas detector, Sulfur hexafluoride - GazDetect | Gas ... 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.
