Car ignition causes and fire precautions

Automobiles are the most widely used transportation tools for modern use. Each unit owns automobiles, and the number of individuals owning automobiles is also increasing. In addition to fuel tanks and oil roads, other components such as tires, interior decoration facilities, etc. are also flammable. There are electric appliances and other power supplies on the vehicles, which are prone to fire.

In the past two years, there have been nearly 40 car fires in Qiyang County. The main reasons are electrical circuit faults, oil circuit faults, and mechanical faults. For example, on September 28th, 2011, a heavy-duty low-profile semi-trailer fired at a 756K position in the Jinghu direction of the Yuyang section of the Beijing-Shanghai Expressway with the license plate number Yu Henan K6497 heavy semi-trailer. The cause of the fire was shaft damage caused by bearing damage, which made the brake shoe friction plate contact with the brake drum. The friction produced a high-temperature pilot tire and caused fire. On July 12, 2012, a license plate for the Su NQ2190 ordinary low-speed truck was parked on the south side of the Tongyang Highway Maintenance Engineering Co., Ltd. of Shuyang County. The cause of the fire was an electrical line failure that caused fire. The fire site is located on the left electrical circuit of the steering wheel in the cab of the truck. The car is a moving object. Once a fire occurs, it is difficult to fight. Combining the investigation of car fires over the years and the summary of accidents, we now discuss with you the fire causes and fire prevention precautions for car fires.

First, the main reason for car ignition

(I) Causes of fire in driving

1. The pipeline of the oil pipeline is damaged, the oil product leaks out, and the electric spark and high temperature catch fire. If the automobile oil pipeline is not firmly fixed or is aging, it can easily cause friction between the tubing and other parts of the automobile, causing wear and leakage of oil on the outer wall of the pipeline, and may cause sparks and high temperatures to catch fire.

2. Damage to the insulating layer of the electrical circuit causes a short circuit and fire. Electrical circuits cover the entire body of the vehicle. During the course of use, if the circuit is worn out, it can easily cause a short circuit in the electrical circuit.

3. The automobile parts are damaged and fall off from the ground, causing ignition of combustibles.

4. After the vehicle is repaired, gloves, rags, etc. are forgotten on the exhaust pipe or the engine. The fire ignites due to high temperature heating.

5. There are cereals and grasses on the highway, which are wound on the rotating shaft to generate friction and heat. In summer village roads, there is often the phenomenon of sun drying on the field. If the vehicle is driving fast on the road that has cereals and grasses, the valley grass is easy to wind on the rotating shaft to cause friction and heat and cause fire.

6. Passengers smoke cigarette butts and cause fire.

7. Passengers carrying chemical dangerous goods on the train cause fire.

8. When carrying flammable cargo, the escorting personnel readily throw cigarette butts or fire from an outside source (such as a chimney flies fire).

9, brake failure (brake friction plate friction high temperature ignition tire) caused a fire.

(2) Causes of fire at parking time Fires occurred while the car was parked. Most of them were caused by fires left before parking, short circuit of electrical circuits, and oil leakage from the fuel tank.

Second, the car fire prevention requirements and precautions

(1) Before the car goes on the road, it is necessary to carry out a serious inspection to confirm that the parts are good, especially the circuit and the oil circuit are in good condition before it can be put into operation to prevent “sick” operation. If there is a malfunction during driving, you must carefully find out the reason for maintenance.

(2) When the vehicle is driving on a road with cereal grass, the driver must pay special attention and keep driving at a low speed. When an abnormal situation is found, the driver should stop immediately for inspection.

(3) It is strictly forbidden for passengers carrying dangerous chemicals to get on the vehicle. If they are found, safety measures should be taken immediately.

(4) When carrying combustible cargo, the goods must be tightly wrapped and covered. Escort personnel and other occupants must not smoke.

(e) Strictly abide by traffic regulations to prevent traffic accidents and trigger fires and explosions.

(6) Mars extinguishers (flame caps) shall be worn on vehicles equipped with chemicals or entering flammable and explosive places and other fire-resisting areas. If a vehicle malfunctions when it enters a fire-fighting area, it must not be repaired on the spot. A fire-extinguishing area should be launched and repaired.

(7) Vehicles shall be equipped with fire extinguishing equipment, such as fire blankets, fire extinguishers, and fire-fighting sand.

(8) In the hot season, do not place flammable or explosive materials such as lighters or toilet water in the windshield or driver's seat of the car to prevent fires caused by high-temperature exposure.
