In the impression of most people,
spontaneous combustion of vehicles is a common thing in summer
but do you know?
The dry and cold winter
is also a high incidence period of automobile spontaneous combustion
Special attention
Although the temperature in winter is low, it is a period of high spontaneous combustion of automobiles, coupled with the dry weather, after the vehicle spontaneous combustion, the fire tends to intensify
recently
3z A truck spontaneous combustion accident occurred on the high-speed ▼▼▼ Recently, a truck suddenly caught fire and spontaneously ignited while driving on the Hangrui Expressway from Zunyi towards Meitan. At the moment of crisis, the driver decisively stopped the vehicle on the right emergency lane. I got down and dialed 110 and 119 to report to the police. After the police arrived at the scene, they immediately organized police to evacuate the onlookers and isolated all the people at a safe distance. In the end, with the joint efforts of traffic police, firefighting, emergency and other parties, after about 40 minutes of rescue, the fire was finally extinguished. Fortunately, the accident did not cause casualties, only the truck body and part of the cargo loaded on the vehicle were damaged. It is understood that the truck driver Oumou drove a light truck loaded with a car of flour and other daily necessities, and when he drove to the road section of the incident, the rear of the vehicle started to catch fire. Currently, the cause of the fire is under further investigation. Winter car spontaneous combustion is different from summer mainly due to oil circuit, circuit, mechanical failure and other reasons at the same time winter the weather is dry static ignition can also be the cause of the car spontaneous ignition 0zzzz z0 What should we do about spontaneous combustion in winter? Z2z is an important cause of spontaneous combustion: components are aging After a hot summer, the pipelines in the car are very easy to age. In the dry and low temperature environment in winter, cars need more mechanical movement to generate the same heat energy. If the car is in poor condition, the rubber and plastic parts in the car are prone to aging and cracking, causing short circuits, and eventually spontaneous combustion. The equipment is modified or replaced improperly. Many new car owners will equip their vehicles with anti-theft devices, replace them with high-end stereos, improve their styling, and possibly add air conditioning. If the modification and replacement work is not handed over to a professional repair shop, it will bury hidden dangers for spontaneous combustion accidents. If the technical level of installers is limited, they will not analyze the wiring layout and specific structure of the vehicle, nor will they consider the calculation of the power of different lines, so as to decide where to obtain the power source is more reasonable. As a result, there will be a variety of wrong repairs such as chaotic lead wires, heavy load places without insurance, and frictional places that are not effectively fixed, and spontaneous combustion accidents will be inevitable. There are combustibles in the car. Today's cars are generally equipped with three-way catalytic reactors. The temperature of this device on the exhaust pipe is very high, but the installation location is relatively low, so parking the car near flammable materials will cause flammable materials to catch fire. stepping on the brakes for a long time The most common driving action-stepping on the brakes, will also generate heat. The heat is generated by the friction between the friction lining fixed on the brake shoe and the brake drum or brake disc. This accumulated heat is not completely dissipated due to driving or the ventilation of the brake drum, but will instead accumulate. If the hydraulic oil leaks, this accumulated heat will heat the oil to its ignition point and catch fire. For example, long-term use of the brake on a long downhill section will easily cause the increase in the temperature of the brake fluid and cause the pressure to rise, which will cause the rupture of the brake oil circuit. The brake fluid will be sprayed onto the hot brake drum and ignited, causing the fire to further spread. How to prevent spontaneous combustion of vehicles A, avoid private modification install and modify electrical equipment such as headlights, anti-theft devices, audio equipment, electric blankets, etc., without analyzing the circuit layout, structure and power of the vehicle, changing the vehicle circuit and increasing the circuit load , The friction-prone parts are not effectively fixed, etc. It is very likely to cause spontaneous combustion. B. Regularly check the line: especially the vehicles with long service life, take preventive measures. The vehicle has a long service life, and the internal wiring of the vehicle is aging, which is prone to leakage. Under high temperature conditions, it may cause spontaneous combustion of the vehicle, especially the vehicle that has been used for more than ten years. C, stay away from flammable and explosive materials Do not place flammable and explosive materials in the vehicle, especially lighters, mosquito killers and other items that are prone to heat expansion and explosion. Splashing fireworks and firecrackers into the interior or bottom of the vehicle, parking the car directly on the residue of the fireworks and firecrackers that have not been completely extinguished, or burning sacrificial supplies and garbage in the surrounding area may cause a car fire. D, standing fire fighting tools in the car: portable fire extinguishers are the most critical and effective fire fighting tools when a fire occurs. is equipped with a fire extinguisher in the car, and has mastered the correct use of the fire extinguisher. If the pressure of the fire extinguisher is found to be too low, it should be replaced in time, so as to save oneself or others in time when spontaneous combustion occurs. What should we do if spontaneous combustion of our car happens? Stay awake and calm to deal with Here are a few steps worth remembering 01 diligent observation In many cases, there will be no open flames at the beginning of spontaneous combustion, but the smell or smoke will be the first to come out. When the car is driving, there will be burning or burning smells. When smoke is emitted from the machine cover, you should be sensitive and vigilant, and pull over for relevant rescue operations. 02 cut off the power When you suspect that the vehicle is about to ignite or has spontaneous combustion, you should quickly park the vehicle to the side of the road, and stay away from the surrounding combustibles, at the same time quickly extinguish the vehicle, and cut off all power in the vehicle. 03 Try to rescue After determining the location of the fire, please find the fire extinguisher immediately and wear gloves to spray and extinguish the corresponding location according to the operation requirements of the fire extinguisher. If it is a fire in the engine compartment, please wear gloves and put a relatively heat-insulating thing between your hands and the engine cover, because if the engine compartment catches fire, the temperature of the engine cover will be very high. Open the engine compartment cover and spray the nozzle of the fire extinguisher into the engine compartment from the gap to reduce the fire. We thought the wrong approach before: We thought that after the engine catches fire, you should never open the engine compartment cover to extinguish the fire, because opening the engine compartment cover instantly will cause a large amount of air to enter the fire area and increase the fire, but this is exactly what Incorrect. The correct approach is: open the engine compartment cover with one hand, and immediately look for the fire point, and then quickly use a fire extinguisher to extinguish the fire , if you find a bottle of fire extinguisher has not extinguished the fire, you can ask the surrounding car owners for help or give up The rescue evacuated to safety. 04 must pay attention to the fact that the capacity of the car fire extinguisher is limited. If the fire is relatively large, you should not expect it to completely help you extinguish the fire. If exceeds 3 minutes and you find that the fire is not under control, then you Evacuate to a safe place as soon as possible. The car burns and burns. Human safety is the most important thing.
