وضع سياج وقائي لفرن الصهر التعريفي

وضع السور الواقي من فرن الصهر التعريفي: there must be a protective fence on the edge of the furnace to prevent people from falling. At the same time, furnace workers must have escape routes, and they must have this awareness before going to work: in the event of an accident, they can escape in time.
