Under conditions such as arc discharge or high temperature, sulfur hexafluoride may decompose into various toxic lower - fluorine compounds, such as thionyl fluoride, sulfuryl fluoride, sulfur tetrafluoride, hydrofluoric acid, etc., which pose various hazards to the human body.
Thionyl fluoride: It is a colorless and transparent gas. It is highly toxic and can cause serious health problems such as pulmonary edema.
Sulfuryl fluoride: It is toxic. Excessive inhalation may lead to congestion in the lungs, thymus, and meninges, and may even cause convulsions and death.
Sulfur tetrafluoride: It is a colorless and pungent - smelling gas. It combines with water to form a smog, is easily inhaled by the human body, attacks the lungs, and causes lung damage and respiratory diseases.
Hydrofluoric acid: It is a highly dangerous and extremely toxic inorganic acid with strong corrosiveness. It can cause corrosive burns and may even lead to death in a short time.
