IEC specifications sf6 Evacuation system

May 25, 2020 · Buildings 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). Type and extent of required measures depend upon location of the room, the accessibility, and the ratio of gas to room volume.
