hexafluoride leakage and quality

Although sulphur hexafluoride is non-toxic and non-flammable, its global warming potential is about 24,000 times higher than carbon dioxide (GWP=23,900). That makes it the most potent of all greenhouse gases, which is why its use is subject to the most stringent environmental regulations.
