Explosive substances: Many production sites produce certain flammable substances. About two-thirds of the underground mines contain explosive substances; in the chemical industry, more than 80% of the production workshop areas contain explosive substances. Oxygen: Oxygen in the air is everywhere. Ignition source: In the production process, a large number of electrical instruments are used, various frictional sparks, mechanical wear sparks, static sparks, high temperature, etc. are inevitable, especially when the instrument and electrical malfunction. Objectively, many industrial sites meet explosion conditions. When the mixed concentration of explosive substances and oxygen is within the explosion limit range, if there is an explosion source, an explosion will occur. Therefore, it is necessary to adopt explosion protection.
