Sulfur hexafluoride is widely used in industrial gases.Then,the high purity sulfur hexafluoride risk level can not be ignored.Here,let's take a look at it together,so that it can be used correctly in the work and avoid causing harm.

　　High purity sulfur hexafluoride is classified as Class 2.2 non-combustible gas in the Chinese national standard GB13690-62 and the List of Hazardous Chemicals(2002 edition),with hazardous characteristics of 5.20 and dangerous goods No.22021.Pure products are basically non-toxic,but products such as mixed low-fluoride sulfur,hydrogen fluoride,especially sulfur decafluoride or oxygen decafluoride disulfide,the toxicity is enhanced.

　　High purity sulfur hexafluoride hazard performance

　　Eye contact:Contact with its fluid and cold vapor can cause tissue frostbite.

　　Inhalation:exposure to oxygen content less than 19.5%of the atmosphere will lead to dizziness,coma,increased saliva,unresponsiveness,nausea,vomiting,loss of consciousness and death,when high purity sulfur hexafluoride exposure to oxygen content less than 12%of the atmosphere will be without any warning loss of consciousness,and lose the ability to self-rescue.

　　Skin contact:Exposure to sulfur hexafluoride liquids and cold vapors may cause frostbite.
