Assessment of SF6 room

Assessment of SF6 room

A12. Yes, we did. The results measured outside the room were below the minimum detectable concentration of our gas analysers. We also released gas tracer outside the room, to check if gas would get inside the room, obtaining again concentrations below the gas analyser limit. Therefore, the protection is considered to be 10^5.

  • Sulphur hexafluoride, SF6 Gas SAFETY - EHS ONE

    5 mins readAug 30, 2020Sulphur hexafluoride is a compound having the formula SF6 At normal room temperatures and pressures it is gaseous and‘has a density of 6.16 g/l at 20 “C and 760 torr (about five times the density of air). Since its critical temperature is 45.6 “C it can be liquefied by compression; it is normally transported as a liquid in cylinders.

  • Myth About SF6 Gas In Electrical Equipment

    8 mins readNov 10, 2014Buildings containing SF6-filled indoor equipment should be provided with ventilation; natural ventilation would normally be adequate to prevent the accumulation of SF6 released due to leakage (see IEC 61634, sub-clause 3.4: “Safety of personnel” and IEC 61936-1).
