3. Safety
Danger caused by decomposition products
Insulating gas in electrical systems may contain decomposition products generated by
electric arcs:
Gaseous sulphur fluorides
■
Sulphur hexafluorides
■
Solid and atomized metal fluorides, metal sulphides, metal oxides
■
Hydrogen fluoride
■
Sulphur dioxide
■
Decomposition products can be harmful to health.
They can cause poisoning by inhalation, ingestion or contact with the skin.
■
They may be irritating to the eyes, the respiratory system or the skin and burn them.
■
Inhalation of large quantities may damage the lungs.
■
Observe the following safety instructions in order to avoid danger from insulating gas:
Wear personal protective equipment.
■
Read the material safety data sheet of the gas supplier.
■
With large leaks, evacuate the area quickly.
■
Ensure good ventilation.
■
Ensure the leak tightness of the equipment with a leak detector (e.g. model GIR-10).

Insulating gas is a colourless and odourless, chemically neutral, inert and
non-inflammable gas which is heavier than air, not toxic and not harmful to
the ozone layer. Detailed information is given in IEC 60376 and IEC 61634.
