Control and suppression of the hottest oil tank fi

As one of the important equipment in the oil depot, the oil storage tank stores a large number of oil products that are easy to burn, explode, volatilize and lose. If the safety management is improper, or due to equipment technical failures and natural disasters, it is very easy to have fire accidents. Therefore, it is very necessary to study the fire control and fire extinguishing Countermeasures after the fire of oil storage tank

1 the risk of oil fire and the overview of oil tank fire at home and abroad

1, 1 the risk of oil fire

many properties of oil are closely related to the possibility of fire or fire, and the properties that constitute the risk of oil fire are volatility, flammability, explosion, electrification, boiling overflow, expansibility, floatability and fluidity

2. Install the mandrel according to the diameter of the processed steel bar and the requirements of the bending machine. 1. 2 overview of oil tank fires at home and abroad. 1. 2. 1 the domestic investigation of oil tank fires in domestic refineries shows that crude oil tanks account for 40% of all tank fires, gasoline tanks (including slop tanks) account for 32%, diesel tanks account for 8%, and heavy oil tanks account for 20%. It can be seen that the oil storage tanks with flash point lower than 28 ℃ account for 72% of all tank fires. Among the causes of fire, open fire accounts for 64%, static electricity accounts for 12%, oil temperature reaching the spontaneous combustion point accounts for 8%, lightning stroke accounts for 12%, and other causes account for 4%

1.2.2 in the statistics of 1500 oil tank fires in foreign countries and the United States, crude oil tanks account for 50% and other oil tanks account for 50%. Among the types of oil tanks, dome roof tanks account for 45%, floating roof tanks account for 30%, and inner floating roof tanks account for 20%. Most fires are caused by static electricity. The investigation of oil tank fires in the former Soviet Union shows that most oil tank fires do not occur in oil fields and depots, but in refineries, of which crude oil and gasoline tanks account for 90%, and other oil tanks account for 10%, and among the types of oil tanks, dome roof tanks account for the largest proportion. 40% of the fires are caused by lightning strikes, sparks from electrical equipment, and open flames used in process devices, and 1/3 of them are caused by man-made fires when cleaning and repairing oil tanks

according to the investigation results of oil tank fire, the dome roof oil tank storing crude oil and gasoline has the highest probability of fire. The floating roof oil tank has good fire safety

2 control and suppression of oil tank fire

in case of oil tank fire, the fire brigade should be responsible for unified command to extinguish the fire. As the commander of the fire, Saudi Basic Industries Corporation (SABIC) not only launched an innovative polypropylene resin product, proficient in various fire-fighting technologies, but also calm on the spot, resourceful and flexible, and can make decisions and decide countermeasures according to the actual situation of the fire. At the same time, it can reasonably mobilize the fire brigade and correctly use all kinds of fire-fighting equipment, and organize the fire-fighting work boldly to ensure the smooth progress of the fire-fighting work. In order to command properly and achieve rapid fire suppression, the following work must be carried out:

2.1 fire investigation

in order to put out the oil tank fire, we should investigate and understand: the type, quantity, oil level and water cushion of the oil stored in the burning oil tank and adjacent oil tanks are also the height of the standard layer for judging the accuracy of the Spring Breaking testing machine, which is committed to providing safe and reliable overall solutions for customers; The damaged part of the combustion oil tank; Whether the fire dike of the burning oil tank is in good condition, and whether the adjacent oil products will be affected if the burning oil tank is damaged; Whether the combustion oil tank will boil over and whether the oil products in the tank can be eliminated; Check whether the drainage system in the oil tank farm is unblocked, and whether the drainage well and water sealing device are in good condition; The current situation of the existing fixed and mobile foam fire extinguishing equipment and the quantity of existing foam agents; Whether the fire-fighting equipment of neighboring units can be supported; Maximum water supply; When the burning oil tank explodes, what is the impact on adjacent buildings (structures), and what measures should be taken to prevent the expansion of the fire
