(1) Before entering the tank area, it is necessary to carefully read the \"Instructions for Entering the Tank Area\" and prepare all necessary safety equipment and tools. (2) The liquid level in the oil tank must be kept within a safe range. (3) No more than 5 people shall be on the tank top at one time, and jumping on the tank top is prohibited. (4) The handrails of the upper and lower tanks should be held firmly. Working on the tank is prohibited in winds of force 5 or above. (5) It is prohibited to enter the tank wearing shoes with nails, and it is prohibited to use non-explosion-proof flashlights on the top of the tank. (6) The fire-resistant gasket of the oil measurement hole should be replaced in a timely manner to remain intact. (7) For oil tanks insulated with iron sheets, the insulation sheets should be painted regularly to prevent corrosion. (8) For oil tanks with insulating ash coats, any fallen or damaged parts must be repaired promptly after maintenance. (9) Ensure that the lightning rod is firmly fixed and has good grounding. The grounding resistance of the large tank should be less than 10Ω during two tests per year, in spring and autumn. (10) Adjust the control to maintain a relatively stable liquid level in the oil tank. (11) For the exposed and poorly insulated bottom drain valves of tanks, proper insulation should be provided in winter to prevent freezing, cracking, and oil leakage. (12) When checking the liquid level, pull and release the float gently to prevent sparks from being generated. (13) Inspect the welding quality of the oil tank in accordance with the standards specified in the operating procedures.
