    Sulfur hexafluoride is primarily of anthropogenic origin but also occurs naturally in minerals, rocks, and volcanic and igneous fluids. Concentrations of SF 6 in air have rapidly increased from a steady state value of about 0.02-0.05 to over 7 parts per trillion during the past 40 years, and are expected to continue increasing.

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride is also routinely used as a tracer gas in laboratory fume hood containment testing. The gas is used in the final stage of ASHRAE 110 fume hood qualification. A plume of gas is generated inside of the fume hood and a battery of tests are performed while a gas analyzer arranged outside of the hood samples for SF 6 to verify the containment properties of the fume hood.

  • Toxic substances list: sulphur hexafluoride - Canada.ca

    Sulphur hexafluoride (SF 6) is a synthetic (i.e., human-made) gas that is colourless, odorless, non-toxic (except when exposed to extreme temperatures), and non-flammable. It is heavier than air and hence stays close to the ground upon release which can cause death by suffocation if large quantities are involved.
