    TRANSMISSION & DISTRIBUTION High voltage switchgear SAFETY SHEET Use and Handling CAUSE OR ORIGIN OF HAZARD. Sulphur hexafluoride (SF ) is a gas which in its basic state is colourless, odourless and tasteless. It is not toxic, but it cannot sustain life. It is a heavy gas that is dispersed slowly into the atmosphere. In its natural state, SF is delivered and stored in pressurized tanks (bottles or spheres) at a pressure of approximately 20 bar at 20°C (in its liquid form) and complies with IEC standard 376.
  • Page 158 TRANSMISSION & DISTRIBUTION High voltage switchgear Whilst SF in its pure state is not toxic, the decomposition products have varying degrees of toxicity.
