Fire Test: How Do We Dispose of a Fire in a Vehicle

Vehicles have become an indispensable means of transportation for people's lives, bringing convenience and efficiency to people's lives. Continuous high-temperature weather in summer is a period of high spontaneous combustion of vehicles. In recent years, auto-ignition accidents due to high temperatures have occurred from time to time.

On the morning of May 10th , officers and soldiers of Daxing Fire Fighting Detachment analyzed the causes and characteristics of car fires at Tianjiao Dismantlement Plant, summed up the current rescue methods and vehicle fire prevention measures in the process of vehicle fire accidents, and simulated the safe disposal of auto-ignition fires on site. Demonstration, for the majority of vehicle owners to popularize the knowledge of car fire safety, beware of car fires.

one,

Causes of common car fires include damage to the oil pipeline and fire, damage to the insulation of the electric circuit, short circuit and fire, damage to the car parts, and friction between the car and the ground to ignite flammable materials and cause fire. The passengers smoke and throw cigarette butts to cause fire, and passengers carry chemical dangerous goods and get into the car and cause fires. , Brake failure (brake friction plate friction high temperature ignition tire) caused fire and so on.

Due to its particularity and individuality, vehicle fires have the following characteristics when they occur:

1,

The interior space of the vehicle is small, and the driver can directly escape from the front door, but for internal passengers (especially passengers of large buses), once a fire occurs, if they do not flee in time, they will be trapped inside the vehicle. And many cases of vehicle fires are caused by vehicle collisions. In this case, the doors may be damaged by squeezing. And when the vehicle is in a special place such as a tunnel, an underground garage, or a maintenance workshop, escape is not only to flee the vehicle, but also to flee the place in time.

2,

The most dangerous vehicle is the oil and gas stored in the vehicle. Gasoline and natural gas are flammable and explosive substances. When the vehicle is used for a certain period of time, the oil and gas pipeline can easily deteriorate, and oil and gas leakage can easily occur during driving. In the event of a vehicle fire, the leaked oil and gas may encounter a spark explosion and affect the surrounding area, expanding the entire accident surface, making it more difficult to carry out the rescue.

3,

Fire in the vehicle, less space on the vehicle, and high fire load per unit area of ​​the vehicle, such as interior trim materials, tires, wooden carriage panels, and seats, etc., will produce extremely high temperatures up to 1100 ° C after combustion. C. Moreover, the vehicle is located on an outdoor traffic road. Under normal circumstances, there is sufficient oxygen for combustion. At the same time, the vehicle is prone to generate a large amount of toxic smoke during the combustion process. When the vehicle catches fire, it will soon spread to the entire vehicle and burn. Evacuation will be extremely difficult.

4,

Vehicle fires, especially large-scale public transport vehicles, are difficult for internal divisions to escape in the event of a fire, which can easily result in mass casualties.
