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.
