Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material. If possible, turn leaking containers so that gas escapes rather than liquid. Prevent entry into waterways, sewers, basements or confined areas. ... Sulfur hexafluoride (2551-62-4) 3000 ppm : 33000 ppm : 200000 ppm (DOE, 2016)sulfur hexafluoride | Sigma-Aldrich

Insulation temperature is by far the most critical variable other than the dew point measurement itself. Tank pressure – the tank pressure directly affects the moisture content calculation and must be accurate. Sensor pressure – the dew point sensor pressure affects the dew point measurement. High flow rates may create a "pressure penalty" and negatively affect the moisture content calculation.[PDF]3M Novec 4710 Insulating Gas
