  • Sulfur hexafluoride - Wikipedia

    Two major factors recommend its use: its concentration can be measured with satisfactory accuracy at very low concentrations, and the Earthatmosphere has a negligible concentration of SF 6. Sulfur hexafluoride was used as a non-toxic test gas in an experiment at St. JohnWood tube station in London, United Kingdom on 25 March 2007.

    Meet SF6, CO2’s Larger CousinWhat Is This Crazy Gas Used for?Why Is SF6 Not Banned Yet?What’s The Effect on Humans?Are There Any Alternatives Out there?Among all the greenhouse gases that exist, CO2 gets the most attention. Today, we bring a different perspective. Think about everything that you know about CO2 and multiply it by roughly 24,000. This is how much a gas called SF6 (sulphur hexafluoride) is stronger than CO2 in terms of global warming potential.You read right: SF6 is the most potent greenhouse gas in existence with a global warming potential of 23,900 times the baseline of CO2.
