Storage tanks safe use guidelines

Oil storage tanks are containers for storing oil products. They often carry some inflammable and explosive materials, which poses a great challenge to the safe use of oil tanks. Therefore, fire inspections must be conducted regularly to ensure the safety of use in accordance with relevant regulations.

The oil storage capacity of the oil storage tank should be operated within the safety tank position, and the fire protection and explosion protection of the oil storage tank and storage tank area should be in accordance with GB50183 and GB50074. Low multiple air foam fire extinguishing systems should be in accordance with GB50151 regulations. Non-explosion-proof electrical equipment and high-voltage overhead lines should not be installed in the tank area. The storage tank area shall be provided with fireproof embankments as required, and the fireproof embankment shall be kept intact. Water storage wells should be set up in the drainage system of the storage tanks. Drains should be provided with valves outside the fire protection dyke. When the tanks are drained, special personnel should supervise and remove residual oil from the wells. The light-transmitting hole, the inspection hole cover, and the gasket of the top of the oil storage tank should be kept intact, and the hole cover should be tightly covered. The oil port should be equipped with a metal washer that does not spark. The flame arrester shall be installed on the base of the breathing valve and hydraulic safety valve on the oil storage tank. Check the flame arrester at least once every quarter. Steel tanks should be equipped with lightning protection and antistatic grounding devices, and their grounding resistance should not exceed 10Ω. The grounding point shall be set at least once every 30m along the bottom of the tank, and the single tank shall be grounded with no less than two points. Two soft copper wires with a cross-sectional area of ​​not less than 25 mm2 are used between the floating vessel of the floating roof tank and the tank wall. Every spring, a lightning protection and antistatic grounding device shall be fully inspected, and the test grounding resistance shall meet the requirements.

The safety alarm needs to be long and the oil tank is the main equipment of the oil depot. Once there is a fire hazard, it will have a major impact. Therefore, it must be observed at all times to increase vigilance.
