  • SF Maintenance Equipment Fundamentals

    Decomposition Although SF 6 is non-toxic in its pure form, it will decompose when exposed to high temperature or electrical arcing – especially in the presence of moisture. The amount of decomposition that occurs is linked directly to the intensity and duration of the temperature and the materials used in the construction of the GIE.
