In recent years, there have been many fire accidents of electric vehicles in China, mainly due to electrical failures. Some people park and charge their electric vehicles indoors, even in common areas such as walkways, stairwells, or living rooms. Since most of the electric vehicle bodies use flammable and combustible materials, once the first is used, the combustion speed is fast, and a large amount of toxic smoke is generated, and it is difficult for personnel to escape, which is very easy to cause.
Electric Vehicles** Hazards.
The hazards of electric vehicles** are mainly manifested in high temperatures and toxic smoke in the fire.
The fire department has done experiments on fires caused by electric vehicle charging, and the experimental data shows that:
Electric car ** 30 seconds, toxic smoke can cover the entire room and corridor, the production of a large amount of toxic smoke, easy to cause accidents.
How fast do electric vehicle batteries and the like burn?
The following set of e-bike combustion experiment numbers gives you a feel for how fast the e-bike battery and other components burn.
When the electric bicycle has a battery short circuit and produces a spark, the flame temperature is 130.
After 30 seconds, the flame temperature rises to 310, at which point the room temperature reaches 120, and the toxic gases cover the entire room.
After 2 minutes, the flame temperature is 680, and the other plastic parts of the electric bicycle are ignited, and the room temperature reaches 180 -220.
At 3 minutes and 30 seconds, the entire e-bike was covered in flames, the temperature reached 1200, and the temperature in the room exceeded 660.
It is worth being vigilant that in electric bicycle accidents, high-temperature toxic smoke is more deadly than open flames. After 20 seconds, the indoor air is highly toxic with hydrogen sulfide. After 30 seconds, carbon monoxide and carbon dioxide have exceeded the limit of human breathing. The toxic gas from the combustion of an electric bicycle is enough to suffocate hundreds of people. Therefore, it only takes 100 seconds for the electric bicycle to kill the person, which is by no means alarmist!
Once the battery**, what to dispose of?
You should call 119 Fire Police** at the first time and seek help from firefighters.
For the early disposal of the battery**, it is recommended to cut off the power first and then use a fire extinguisher to extinguish the flame on the premise of protecting its own safety. If you find that the battery is still smoking, you should immediately use plenty of cold water to cool it down.
Experts especially remind that for the battery, it must be analyzed on a case-by-case basis. Once it is found that it is impossible to deal with it in the early stage, it should be evacuated immediately and the surrounding people should be evacuated.
