    The loss rate of sulphur hexafluoride is generally about 0.5 percent by volume of SF 6 per year. These leaks must be eliminated immediately, since sulphur hexafluoride is extremely harmful to the environment. Depending on the operating duration SF 6 must therefore be checked and replaced regularly.

    The density of sulfur hexafluoride is relatively high at room temperature and pressure due to the gaslarge molar mass. Unlike helium, which has a molar mass of about 4 g/mol and pitches the voice up, SF 6 has a molar mass of about 146 g/mol, and the speed of sound through the gas is about 134 m/s at room temperature, pitching the voice down. For comparison, the molar mass of air, which is about 80% nitrogen and 20% oxygen, is approximately 30 g/mol which leads to a speed of sound of 343 m/s.
