Sulfur hexafluoride gas has insulation and arc extinguishing properties,good chemical stability,so its application areas are expanding.If used improperly,it will do great harm to human body and the environment.But there are still some problems with the current usage.

　　First of all,environmental awareness is weak.Due to the lack of environmental protection knowledge,some people do not know enough about the performance of sulfur hexafluoride gas.In the production and use,due to improper use and management,the leakage and man-made emission problems are serious.

　　Secondly,recycling reuse,or recycling treatment is not good.The recovery rate is low because sulfur hexafluoride gas recovery units are expensive and inefficient.And the recycling treatment is poor,the waste gas is almost all directly discharged into the atmosphere.

　　After the revolution,the management system is not in place.Sulfur hexafluoride manufacturers have no complete rules and regulations for the use and management of sulfur hexafluoride.Some assembly workshops,maintenance rooms and other workplaces do not have sound ventilation facilities and monitoring equipment.
