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.
SF6 and Oxygen Depletion Monitoring in Substations ...· SF6 is used in high and medium voltage switchgear as an insulating medium, provides a risk of asphyxiation to site personnel in the event of a gas leak. The Austech system is designed to provide warning and evacuation alarms to site personnel in the event of an SF6 gas leak from gas filled plant or storage bottles.
