How are the explosion protection classification levels determined for the chlorosilane purification workshop, the reduction furnace off-gas recovery workshop, the trichlorosilane synthesis workshop, and the chlorosilane storage area in polysilicon plants, and what is the basis for this? How should the explosion protection rating for electrical and instrumentation equipment in the aforementioned workshop be selected? How to choose the explosion-proof rating for electric hoists?

How are the explosion-proof area classifications determined? The main reference standard is GB-3836.14 for the classification of hazardous areas
