1. Preparation before cleaning
Drain the oil completely: Before cleaning, make sure that the oil in the engine oil tin can is completely drained.
Cut off the connection: Cut off all connections between the oil tank and the external pipeline, and set obvious isolation signs at the connection.
Ventilation: Open all openings of the tank body for sufficient ventilation to ensure that the oil and gas concentration in the tank drops to a safe range.
2. Measures to prevent leakage
Check the tank structure: Before cleaning, conduct a comprehensive inspection of the oil tank to ensure that the tank structure is intact and there are no safety hazards such as leakage and deformation.
Use explosion-proof equipment: During the cleaning process, use explosion-proof motors and switches to ensure that the equipment is well insulated.
Set up containment measures: Set up secondary containment measures such as dikes or barriers in the cleaning operation area to limit leakage and prevent it from spreading to the environment.
3. Precautions during cleaning
Control the water flow rate: When filling the tank with water, the initial flow rate should be controlled at about 1 m/s to avoid leakage caused by excessive water flow.
Use professional equipment: Use professional cleaning equipment, such as high-pressure water guns and vacuum pumps, to ensure the safety and efficiency of the cleaning process.
Monitor oil and gas concentration: During the cleaning process, regularly monitor the oil and gas concentration in the tank to ensure that it is below the lower explosion limit.
4. Post-cleaning treatment
Check the tightness: After cleaning, check the tightness of the tank body and lid to ensure that there is no leakage.
Properly handle wastewater: The wastewater after cleaning should be properly handled to avoid direct discharge into the environment.
