Sulfur Hexafluoride – SF6

On this page sulfur hexafluoride ( SF6 ), suitable detection tools –  SF6 gas detector  – and information on respiratory protective equipment (self-contained breathing apparatus and supplied-air respirator).

Sulfur hexafluoride (SF6) properties

Sulfur hexafluoride ( SF6 ), insulation properties It is mainly used in electrical applications due to . Therefore, it can be used in electrical cabinets, power transformers and capacitors… It is also a tool to detect gas leaks or monitor freon-powered cooling systems. audience It is used as. It is applied in the medical field and also as a contrast agent for cardiac and vascular examination.

Health effects of sulfur hexafluoride

Sulfur hexafluoride ( SF6 ) colorless , odorless It is heavier than air and is not considered toxic. However at high concentrations (displaces oxygen) is asphyxiating, as are inert gases (also called noble gases). Sulfur hexafluoride does not have lower or upper explosive limits, but May react seriously with disylane and may form a dangerous explosive gas mixture.

SF6 easily hydrolyzes in water highly toxic and corrosive substances It turns into fluorinated compounds (thionyl fluoride and hydrogen fluoride). It is also one of the six gases responsible for the greenhouse effect under the Kyoto Protocol (one kilogram released into the air is equal to approximately 23,000 kg of carbon dioxide (CO2) in the long term).

SF6 gas detector – Sulfur hexafluoride

Since sulfur hexafluoride is absolutely undetectable without appropriate equipment (odorless and colorless gas), there is only one The SF6 detector can accurately measure concentrations of this suffocating gas and appropriately monitor SF6 gas hazards. Therefore, a fixed or portable detecting sulfur hexafluoride It is recommended to use the device or a complete system.
Sulfur hexafluoride calibration gas cylinders are available for calibration and gas testing of your fixed or portable gas detectors

Sulfur hexafluoride respiratory protection – SF6

Due to the suffocating properties of SF6 gas and the high risk of suffocation, open-circuit equipment should be used for long-term interventions. self-contained breathing apparatus (SCBA) or air supply respirator It is recommended to use .
