About insulating gas Sulfur Hexafluoride (sf6 gas) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas which is an excellent electrical insulator. Sulfr hexafluoride has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. Sulfr hexafluoride was discovered by Henri Moissan and Paul Lebeau in 1901 Sulfr hexafluoride used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipments, often replacing oil

These are large molecules, are inert (don’t react with tissue) and can expand at given concentrations. Their large size means that they will be slowly absorbed after injection, giving us plenty of time to use them as a tool.
