How to do a good job in the safety management of oil depots (stations) and what measures have been taken?

(A) oil depot fire prevention measures

1. When selecting the warehouse location, fire safety should be considered.

① The location of oil depot should try to avoid military strategic targets such as large and medium-sized cities, large reservoirs, important transportation hubs, airports, power stations and key industrial and mining enterprises, so as to avoid mutual influence and increase various unsafe factors. (2) The oil depot should be located in a place with convenient transportation, so as to facilitate the arrival of fire engines as much as possible. Railway oil depots should be close to places where conditions permit, and water oil depots should be close to places where conditions permit buildings to load and unload oil products. (3) The storage site of the oil depot should be located in a relatively flat place, and the natural terrain of the storage site should have a relatively obvious slope, and the slope of the natural terrain should not be less than five thousandths, so as to facilitate the drainage of the oil depot and the self-flow operation of oil products. If the reservoir is built in hilly area, it is advisable to choose a place with low terrain and not submerged. (4) When there is an open fire around the oil depot, the location of the oil depot should be selected in the crosswind direction of the perennial dominant wind direction. When the crosswind direction is difficult to locate, it should be selected according to the possibility of open fire in Fei Huo. If there is no possibility of fire in Fei Huo, you can choose the downwind direction of the fire; If there may be a fire in Fei Huo, choose the upwind direction of the fire and have enough safe distance (generally not less than 30m). ⑤ When the oil depot is located on the shore, it should keep a corresponding safe distance from residential areas, docks and bridges. , and should be located in the downstream area of the river, so as to avoid oil flowing downstream in case of fire. ⑥ Seismic facilities should be considered when building oil depots in earthquake areas. 1- 1 oil depot should not be built in the earthquake area where the earthquake ground fissure is greater than or equal to 9 degrees. ⑦ The storage location should be in a place with good geological conditions. It is not suitable to be built in areas with landslides, faults, landslides, swamps, quicksand and mudslides, and it is not suitable to be built in three-level collapsible macroporous land areas. Safe distance between oil depot and surrounding enterprises, residential areas, traffic lines, etc. Should comply with the relevant provisions of the state. 2.

Doors and windows are opened at both ends of the pump room, and the doors open outwards. The natural lighting area of the window should not be less than 1/6 of the area of the pump room, and the indoor ventilation is good. Ventilation and exhaust of underground and semi-underground light oil pump houses should not make the oil and gas concentration in the pump houses exceed 1.58% (by volume). There shall be no stuffy roof and interlayer in the pump room; The building foundation cannot be connected with the pump foundation. Explosion-proof lighting should be used in the pump room. When powered by an internal combustion engine, the fuel tank for the internal combustion engine should be set on the incombustibility basis without doors and windows outside the pump room wall, and control valves should be installed at both ends of the oil lead pipe leading from the ground up to the internal combustion engine. When the oil pump conveying different oil products is installed in the pump room, the requirements of the pump room should meet the requirements of conveying the oil products with the lowest flash point. It is forbidden to install temporary and unqualified equipment and lay temporary pipes in the pump room; Belt drive shall not be used. /kloc-When the power distribution device, metering instrument station and staff lounge with voltage below 0/0kV are arranged in the auxiliary building adjacent to the pump room, they must be separated from the pump room by a solid partition wall made of incombustible materials, and the partition wall is only allowed to pass through the cable (wire) protective sleeve related to the pump room; The holes in the wall bushing should be tightly filled with incombustible materials, and each hole should have a separate access door. The shortest distance between the doors and windows of the pump room and the doors and windows of the power distribution room should not be less than 6 meters. If limited by conditions, an automatic closing device should be set, and the window is a fixed window that cannot be opened. The ground of the power distribution room should be 0.6m higher than that of the pump room. For the pump room with vacuum system, the vacuum tank should be located outside the pump room. There should be facilities for introducing oil into the oil collecting well through water seal at the valve group of the pump house, and the oil collecting well should be covered and pumped out. The clear distance between pumps and between pumps and walls is generally1m. Pay attention to the inspection and maintenance of the oil pump system at ordinary times to ensure that the oil pump, valves and pipelines are watertight; The auxiliary instruments are complete and sensitive, and equipped with sufficient fire-fighting equipment. 3. Oil pipeline

Oil pipelines are widely distributed in various operation areas of oil depots, and there are mainly three layout forms: underground laying, underground laying and pipeline laying. Fire protection requirements: (1) Do not lay oil pipes above or below buildings. When crossing the roads where railways and motor vehicles pass in the warehouse, the crossing angle should not be less than 60 degrees, and steel sleeves should be protected outside the pipes. The outer wall of the casing shall not be less than 0.8m, the road surface shall be more than 0.6m, and both ends of the casing shall cross the road at least 2m. The pipes in the casing shall be welded. (2) The above-ground oil pipe shall be erected on a cross frame made of incombustible materials, and its insulation layer shall be incombustible glass wool, asbestos mud and other materials. Keep a distance of not less than 3m from the wall of buildings (structures) with doors, windows and holes, and a distance of more than 1m from the wall of buildings (structures) without doors, windows and holes. When crossing the railway, the clearance height should be greater than 5.5 meters; When crossing the expressway, it should be more than 4.5 meters; When crossing the sidewalk, it should be more than 2.2 meters. (3) When the buried depth of underground oil pipeline is lower than the foundation depth of adjacent buildings (structures), it shall be implemented according to the provisions of the above-ground pipeline. The underground pipeline intersects with the cable, and the oil pipe should be no less than 1 m under the cable; When crossing the sewer, you should pass at the depth of 1.5m under the sewer. Various items are piled up above the ground where underground pipelines pass. (4) Multiple pipes shall be laid in parallel, and the spacing shall not be less than 10 cm. The steam pipeline is not allowed to be laid in parallel with the pipeline conveying light oil products. Oil pipelines laid on the ground and in open ditches should be equipped with compensators, which expand with heat and contract with cold as needed. (5) The tubing shall be subjected to pressure test regularly (once a year or twice a year), and the test pressure shall be 1.5 times the working pressure. (four) there are perfect anti-static and lightning protection facilities.

1. Antistatic

The tank, pipeline and oil loading and unloading facilities of the oil depot shall be grounded with anti-static electricity, and the grounding resistance value shall not be greater than 100 ohm. In order to reduce the generation of static electricity, some measures can be taken, such as controlling the flow rate of oil crystals and leaving enough time for oil to eliminate static electricity when adding anti-static filtration. 2. Lightning protection law

In order to ensure the safety of the oil tank, the oil tank needs to be equipped with lightning protection devices. At present, the common lightning protection devices are lightning rod, lightning net, lightning belt and lightning wire. (five) the safe oil storage capacity of the oil storage container

Strictly controlling the capacity of oil tank is very important for fire fighting and fire prevention. The safe oil storage height and safe capacity of oil tanks are determined and calculated according to relevant regulations. The filling quantity of oil crystals in oil drums should be determined according to the seasonal climate, and the filling coefficient of oil drums should be kept at 93-95%. (6) Fire prevention requirements for oil tank cleaning and oil depot maintenance.

1. Oil tank cleaning

Leakage or other damage to the fuel tank requires emptying inspection or hot work maintenance. The general procedure is to clean the empty oil tank, remove the oil and gas in the tank, and then carry out maintenance and construction. There is a great risk of fire and explosion in the process of tank washing, exhaust and construction, so it is necessary to strictly regulate the operation and take strict fire prevention measures. (1) General requirements for cleaning. Before cleaning, a leading group composed of leaders, technicians and security guards should be set up. It is necessary to delimit the scope of the dangerous area, stop the operation of the adjacent tanks in the dangerous area, set up a warning area, equip with necessary fire-fighting equipment, and designate a special person for on-site monitoring or firefighters to be responsible for monitoring. In order to improve the safety of cleaning oil tanks, transitional measures can be taken to change the oil storage mode. (2) When cleaning the oil tank, the oil pipeline cannot be used instead of the water inlet pipe to clean the oil tank; Don't spray water or water from the top of the oil tank, and don't flush the oil tank wall with high-pressure water gun or steam. The washed oily sewage is discharged into a special sewer, and the bottom liquid must be pumped up. Pumping equipment must be explosion-proof and anti-static. Operators should wear clothes and shoes that will not generate static electricity. Oil collection operations should be stopped in cave warehouses or hidden warehouses covered with grapes. After plate replacement or other welding operations are carried out in the tank, the water pressure test shall be carried out according to the regulations, and it can be sealed and delivered only after it is qualified. 2. Oil depot maintenance

(1) General requirements for maintenance of hot work. On-site inspection should be conducted before hot work, and feasible construction and fire extinguishing schemes should be formulated. Before construction, weeds, sludge and other combustible materials around the hot work site should be removed, and necessary safety testing equipment and fire fighting equipment should be equipped. Fire fighting equipment and fire extinguishing devices in the oil tank area should be reliable, and skilled technicians should be assigned to operate during construction, and full-time (part-time) firefighters or fire brigades should be assigned for on-site monitoring, just in case. (2) Thermal maintenance of the fuel tank. Remove all oil products in the maintenance tank, wash the dirt on the tank wall with a fire water gun at the manhole of the tank, and pump out the accumulated oil in the tank. Clean dirty oil and rust should be buried in an underground safe place outside the tank. The deposited dirt of sulfur-containing oil products must be buried in the warehouse in time in wet state. Before hot work, whether there is explosion danger should be analyzed through gas samples, or oil and gas should be detected by explosion detectors at various orifices such as measuring holes and lighting holes, as well as at the tank bottom and dead corners where oil and gas are easy to accumulate, such as risers and central columns. Pay special attention to the poor welding seal at the bottom of the oil tank, which may store oil at the lower part. It is best to use more than two explosion detectors to measure at the same time, so that the data can be checked and the illusion caused by the failure of explosion detectors can be prevented. (3) Thermal maintenance of oil pipeline. Before hot work, after removing the accumulated oil in the pipeline, dismantle the oil pipeline, thoroughly clean it with water, open the nozzle for ventilation, and move it to the designated place for hot work. For the unconditionally disassembled oil tank pipeline, after the oil in the pipeline is removed, corresponding safety and fire prevention measures should be taken to weld the pipeline according to the danger degree of the oil transported in the pipeline. The light oil port in the oil tank within 20 meters from the pipeline welding should be moved to another oil tank and filled with water. Both ends of the repaired pipe section shall be removed and kept open. The ends of unrepaired pipe sections shall be closed with blind plates. If steam is used to flush the pipeline, it is necessary to prevent vacuum from being generated when the pipeline is cooled, and oil or gas will flow out of the unopened pipeline, resulting in fire danger during hot work. (7) Improve fire control facilities.

1. The oil depot should comprehensively consider the fire-fighting facilities according to the form of oil tank, the fire risk of oil products, the grade of oil products and the fire-fighting cooperation with surrounding units. Fire fighting facilities in oil depots generally include fire water supply and air foam fire extinguishing system. Fire water supply includes fire water supply pipes, fire hydrants, fire pumping stations, fire pools and other facilities. Air foam fire extinguishing system includes fire foam pump house, foam liquid tank, foam supply pipeline, foam generator and other facilities. The design and installation of fire fighting facilities shall meet the requirements of relevant codes. 2. All kinds of places in the oil depot should be equipped with fire-fighting equipment according to the needs of fire fighting, and their types and quantities can be comprehensively considered according to the nature, danger, area and other factors of the place. 3. Fire-fighting facilities and fire-fighting equipment should be maintained regularly, and the dressing should be tested regularly to keep them in good condition. 4. The oil depot must make a fire-fighting plan according to the actual situation, and prepare charts and explanations as the main content of fire-fighting training. After the fire fighting plan is formulated, it shall be reported to the superior and the public security organ.
