Fire fighting technology of gas station

fire refers to the accident of property loss or personal injury caused by uncontrolled combustion in time or space. The burning phenomenon that does not cause loss or casualties is called fire or fire alarm. Fires develop from small to large. The general development process is divided into four stages: combustion, stable combustion, expanded combustion and extinction. In the initial combustion stage, the combustion is unstable, the temperature is low, the flame is not high, and the combustion area is small. In the stable combustion stage, a large amount of heat is released, which further promotes the decomposition of combustibles. The combustion starts to be stable, the temperature rises, the combustion is fierce, and the radiant heat is large. In the expanded combustion stage, the combustion area is large, the temperature is higher, and the radiant heat is stronger, so that the adjacent combustibles are ignited, and the fire expands. In the extinguishment stage, the combustibles oxidize rapidly, basically burn out, and gradually extinguish, and self extinguish without fire fighting

it can be seen that to effectively extinguish a fire, it should be in the initial combustion stage of the fire or in the stable combustion stage, otherwise the success rate is very low. The fire fighting policy of gas stations is also based on this foundation. The fire control of the gas station shall be in accordance with the policy of "prevention first and combination of prevention and elimination" proposed in the general provisions of the national fire control regulations. Fire fighting is essentially an invisible increase in production and saving

determination of fire fighting plan for gas stations

in order to take the initiative in fire fighting at gas stations, effectively put out fires and reduce fire losses, fire fighting preparations should be made at ordinary times. Fire fighting plans should be formulated according to the specific conditions of gas stations, and charts and descriptions should be prepared as the main basis for training and actual combat. The main contents include:

(1) organizational leadership and command system

(2) the geographical location of the gas station, the location, quantity and volume of storage tanks, the location and quantity of fuel dispensers, the direction of oil pipelines, and the storage location and quantity of other oil and other combustibles

(3) structural form, fire resistance rating, area, height, internal facilities and distance between buildings

(4) allocation and division of fire fighting personnel, arrangement of security forces, material rescue, personnel evacuation measures and corresponding operating procedures

(5) quantity, placement and emergency supplementary measures of various fire-fighting equipment

(6) external communication, deployment and command of foreign aid forces, etc

precautions in case of fire in the gas station:

in case of fire in the gas station, proactive measures shall be taken to obtain fire-fighting equipment locally and put out the fire. In case of fire spreading, while taking effective preventive measures, report to the fire department as soon as possible

(1) actively cut off the power supply, stop all operations, and close the valve

(2) quickly organize fire fighting according to the fire-fighting plan. According to their respective division of labor, those who should give an alarm should give an alarm without delaying the fighters

(3) evacuate people and vehicles in an orderly manner, and there should be someone on both sides of the entrance and exit to monitor and control

(4) collect and handle tickets, cash and other valuables in time

(5) guide external force support

fire fighting methods for gas stations

1. fire fighting for vehicles in the receiving and dispatching operation of gas stations

(1) in case of fire during oil collection, the fire must be put out immediately, and the oil drain valve of the oil tank truck must be closed. If necessary, the truck shall be quickly evacuated from the site

(2) if the fuel tank is on fire during refueling, the fuel tank can be blocked with asbestos blanket to suffocate the fire. Or dry powder fire extinguisher

(3) if the motorcycle engine is on fire, stop refueling, try to cover the fuel tank cap, and then put out the fire with a fire extinguisher

(4) when a fire occurs in a vehicle and cannot be extinguished at the moment, the vehicle must be extinguished and evacuated from the service station to continue to extinguish. At the same time, command the on-site vehicles to evacuate quickly and calculate automatically: automatically calculate various experimental results to prevent spreading

2. methods to put out the fire of oil tank truck

(1) if the oil tank truck catches fire during oil unloading, first stop unloading, quickly drive away from the site, and then put out the fire

(2) if the tank mouth of the oil tanker is on fire, stop unloading oil first, cover the tank mouth with asbestos blanket, or block the tank mouth with other covers (such as wet cotton clothes and wet gunny bags) to put out the oil fire. When the fire is fierce, use a fire extinguisher to aim at the tank mouth to put out the fire

3. fire fighting in station building or operation room

(1) stop refueling, cut off the power supply and close the oil tank valve

(2) organize personnel to put out the fire quickly with fire extinguishers

(3) command refueling vehicles to leave the service station immediately to prevent accidents

4, fire fighting of oil fires in open containers

open containers have a large evaporation area, so it is easy to cause a fire if gasoline is filled in an oil basin to clean automobile or other mechanical parts. In case of fire of oil products in open containers, the fire fighting methods are as follows:

(1) do not use water pouring, and do not rush to take out the parts in the basin, so as to prevent the oil fire from being brought out of the basin or splashing on people when taking out the parts, or overturning the oil basin when taking out the parts, which will spread the oil fire in all directions, making it difficult to put out the fire

(2) use the dry powder of the gas station, or foam and carbon dioxide fire extinguishers to put out the fire

(3) fire containers can also be covered with asbestos or soaked cotton quilt and gunny bag to suffocate the oil fire

5. electric fire fighting

(1) in case of an electric fire, first cut off the power supply, and then put it out with a carbon dioxide or dry powder extinguisher

(2) it is forbidden to use foam extinguisher, water and wet quilt to extinguish electrical fires

(3) when the power supply cannot be cut off, the fire extinguishing personnel shall wear fire-resistant and insulated shoes and clothing to prevent electric shock. Then use carbon dioxide fire extinguisher or dry powder fire extinguisher to directly spray extinguishing agent to the electrical ignition source for fire extinguishing, and try to cut off the power supply as soon as possible, and then put out the fire comprehensively

6. when the gas station threatens the safety of the whole gas station due to the combustion or explosion of oil vapor, the following procedures shall be taken to put out the fire

(1) stop refueling immediately, close the valve and cut off the power supply

(2) clear and dredge the fire roads inside or outside the station, and give a fire alarm

(3) command the refueling vehicle to leave the gas station quickly, and send personnel to wait for and guide the fire truck at the intersection

(4) organize the on-site personnel to use the existing fire-fighting equipment in the station to put out the fire, and transfer the oil drums and other small oil storage containers to minimize the fire loss

(5) cooperate with the fire brigade to put out the fire according to the predetermined scheme

7. fire fighting on people

when people are on fire, they often panic or rush to find someone to rescue them. This method is wrong. Because when people are covered with oil and fire, they usually burn clothes first. If people run away and the clothes on fire get enough air, the fire will burn more violently. In addition, once the person on fire runs away, it is bound to bring the fire to the place passing by, which may expand the fire. Therefore, the following points should be paid attention to when people catch fire:

(1) when clothes can be taken off, they should be quickly taken off, immersed in water, or stamped out with feet, or extinguished with fire extinguishers and water

(2) if it is too late to take off the clothes, roll on the spot and put out the fire

(3) if more than two people are present, the person who is not on fire should be easy to operate; The microcomputer control is very powerful and calm. Immediately cover, beat or water the fire spot on the person on fire with the sacks, clothes, brooms, etc. that are readily available, or help him take off his clothes. However, it should be noted that fire extinguishers should not be used to spray on the person's body to avoid expanding the injury

fire fighting of liquefied petroleum gas (LPG) filling station

lpg fire fighting mainly refers to the on-the-spot fire fighting at the initial stage. The usual measures are as follows

1. stop the leakage and put an end to kindling

eliminate the leakage of LPG and put an end to the generation of kindling, which is the most important step to eliminate the spread of fire. No matter whether a fire occurs or not, when LPG continues to leak from the process unit, measures shall be taken immediately to control the leakage point, cut off the power supply and prohibit all open fires

(1) when closing the valve on the leakage pipeline, stand in the upwind direction and leave the fog area. Close the upstream valve closest to the leakage point as far as possible

(2) in case of leakage without fire, fire shall be strictly prevented during plugging, non explosion-proof electrical appliances shall not be used, collision and collision between metal objects shall be prohibited, and a warning area shall be set around, and no fire source shall exist in the warning area

2. control the fire area and put out the fire

while cutting off the gas source, fire-fighting equipment should be used to disperse LPG gas with spray water gun, and spray dry powder or dioxygen into the fire area. Trans isoprene rubber, dynamic vulcanized rubber, long carbon chain nylon and biological polyurethane, which have won the national science and technology award, represent China's achievements in the field of carbon extinguishing agents, so as to block the continuous contact between air and flames and liquefied petroleum gas, This work shall be carried out even if the air source is not completely cut off

3. close organization and proper command

in case of LPG fire, the on-site staff of the gas station shall keep calm, deal with it rationally, take corresponding countermeasures quickly and give an alarm in time. The station master shall immediately take the responsibility of organizing fire fighting, accurately judge the fire, reasonably dispatch and command, correctly take countermeasures, and extinguish the fire according to the fire fighting plan
