gaz sf6, Cattle, and AI: the increasing need for an “AnaMin

Sep 23, 2019 · The cause of deaths points to the accumulation and persistence of leaked Sulfur Hexafluoride (Sulfr hexafluoride) gas from turbines. Turbines use the gaz sf6 gas as part of combustion-risk retardant. The gas is heavier than air. And so, by its very nature, leaks of the gas immediately drop to the lowest points of elevation around the area of the turbine. Wherever the gas lands, it starts to pool in increasing concentrations, and easily inhaled by the cattle grazing farmland.Get price
