    5) In accordance with the provisions of the tank structure and process conditions, should be clearly defined maximum oil tank height, (safe height) and the minimum oil height, oil, oil should be strictly controlled within the maximum oil within the height . Pumping oil, not less than the minimum oil height,

    6) Open the oil hole, the operator should stand in the upper hand to ensure that the absorption of fresh air, the amount of oil, the foot along the oil hole in the aluminum (or copper) guide groove down to avoid steel tape measure and hole Wall friction occurs sparks, check feet, the amount of oil hole cover should be tightly sealed, and pay attention to whether the cover gasket is intact.

    9) oil heating temperature should be 15 ℃ lower than its flash point, due to operational needs, must raise the temperature, it shall not exceed 90 ℃, so as not to cause water inside the oil bumping accident.

    10) heavy oil tank for dehydration operation, the oil temperature is heated to 80 ℃ as well, open the valve by the small open - open - a small open principle, the operator should adhere to the post, in order to avoid running oil accident.

    15) tank cleaning should be a detailed inspection of the tank and the status of various accessories, especially the lower manhole is closed tight, dehydration valve is closed, after the correct before the oil.

    16) Check regularly whether the respiratory valve action is sensitive, especially in the winter should pay attention to the valve of the valve and safety valve at the bottom of the water not to freeze, to prevent the oil out of the operating pressure over the permissible range and drum open , On the breathing valve and safety valve below the fire, but also regular checks to avoid clogging.

    17) irrigation areas are not allowed to wear chemical fiber clothing and nail shoes on the tank, are not allowed to hit the iron in the tank top, also not allowed in the top of the switch flashlight.
