Sep 16, 2020How to operate SF6 Leak Detector: When operating a handheld leak detector, it is best practice to start the device out on the highest setting, which measures down to 5 ppmv sensitivity. As you start to find a leak, lower the sensitivity because the source of the leak will have the highest concentration of SF6.

Synthesis and ReactionsApplicationsGreenhouse GasPhysiological Effects and PrecautionsSee AlsoFurther ReadingExternal LinksSulfur hexafluoride on Earth exists primarily as a man made industrial gas and has also been found to occur naturally. SF6 can be prepared from the elements through exposure of S8 to F2. This was also the method used by the discoverers Henri Moissan and Paul Lebeau in 1901. Some other sulfur fluorides are cogenerated, but these are removed by heating the mixture to disproportionate any S2F10 (which is highly toxic) and then scrubbing the product with NaOH …See more on en.wikipedia.orgChemical formula: SF₆Molar mass: 146.06 g/molMelting point: −64 &C; −83 &F; 209 KSolubility in water: 0.003% (25 &C)SULFUR HEXAFLUORIDE HAZARD SUMMARY Sulfur Hexafluoride nj.gov/health/eoh/rtkweb/documents/fs/1760.pdfPDF fileSULFUR HEXAFLUORIDE page 2 of 6 This Fact Sheet is a summary source of information of all potential and most severe health hazards that may result from exposure.

EC Number: 219 854 2Gmelin Reference: 2752RTECS number: WS4900000UN number: 1080OverviewSulfur hexafluoride (SF6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non flammable, and non toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L). It is generally transported as a liquefied compressed gas. The concentration of SF 6 in Earth's troposphere reached 10 parts per trillion (ppt) in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugitive emissions from banks of SF 6 gas contained in its medium and high voltage switchgear. Uses in magnesium, aluminum, and electronics manufacturing also hastened atmospheric growth.
