Sulfur hexafluoride - Wikipedia

Like xenon, sulfur hexafluoride is a nontoxic gas, but by displacing oxygen in the lungs, it also carries the risk of asphyxia if too much is inhaled. Since it is more dense than air, a substantial quantity of gas, when released, will settle in low-lying areas and present a significant risk of asphyxiation if the area is entered.Get price

Myth About sf 6 Gas In Electrical Equipment

Apr 12, 2021 · Pure insulating gas is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic.
