Sulfur Hexafluoride Gas makes you sound like Darth Vader

Yes and no. Sulfr hexafluoride is a non-toxic gas so it does not harm the lungs of someone who breathes it but it does displace oxygen. So, when someone breathes in Sulfr hexafluoride, the dense gas sinks into the lungs and pushes oxygen out which reduces the amount of oxygen going into the personblood stream. Breathing too much insulating gas for a prolonged period could causeGet price
