Reference answers: (1) Check whether the screws of each manhole are tightened; (2) When oil reaches the manholes, verify for any leaks; (3) As the liquid level rises and pressure increases, constantly check the tank bottom and walls for leaks.
(1) Contact the relevant parties to find out the quality, quantity, tank number, and pipelines used for the oil received; (2) Check whether the oil reception pipelines and valves are in good condition; (3) Check the oil dipstick and oil temperature
