The pure sulfur hexafluoride gas is non-toxic, but when the high current is switched off, some low fluoride containing sulfur will be produced due to strong arc discharge. These substances have a strong reaction ability, when there is water and oxygen will be further reaction with electrode materials, water, and thus decomposition to produce toxic or highly toxic gas. These toxic gases mainly damage the respiratory system of the human body, poisoning will be similar to the cold, skin allergy, nausea and vomiting, fatigue and other adverse reactions, inhaled large dose, there will be more serious consequences. So, sulfur hexafluoride is also dangerous.

Sulfur hexafluoride is filled with high-pressure cylinders, which are transported by air and land. As it is a gas form, it belongs to dangerous goods. But in peacetime production, experiment and other USES, sulfur hexafluoride is non-combustible, chemical properties are stable, often used as inert protective gas, so it is not dangerous goods.
