Diesel is generally used for cleaning emulison bitumen equipment. If the equipment has a certain thickness, it can be cleaned by physical methods first, and then washed with diesel. When the bottom oil of the cavern of the emulison bitumen equipment is sucked, the ventilation system is started to ensure ventilation and ventilation of the workplace.

Secondly, oil and gas poisoning accidents are very likely to occur during the removal of dirt at the bottom of the emulison bitumen equipment. Protection work should be done to prevent poisoning.
In addition, the technical status of the ventilation equipment should be checked and the fan should be started for ventilation and ventilation. The cavern asphalt tank and the semi-underground asphalt tank should be ventilated continuously. When the ventilation is stopped, the opening on the asphalt tank should be sealed.
For the inspection of the protective clothing and respirators of the personnel of the emulsified asphalt equipment, check whether the tools and equipment used meet the explosion-proof requirements, and enter the asphalt tank to remove the dirt after passing the inspection.
