  • Assessment of the sulphur hexafluoride (SF 6) tracer

    During the Chamber period, continuous air samples were drawn into evacuated PVC yokes as per SF6 tracer technique from each chamber’s outflow gases and from the com- mon inflow. Yokes were analysed off line and the tracer procedure used to calculate CH4 emissions while sheep were in chambers (hereafter named ‘Tracer in chamber’).

  • Myth About SF6 Gas In Electrical Equipment

    May 25, 2020Pure SF6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Legislation for chemicals does not categorise SF6 as a hazardous material.
