What is the cause of bus spontaneous combustion in Liling, Hunan?

In recent years, natural disasters, man-made disasters, accidents, typhoons and rainstorms have just been brought under control in COVID-19, and there will be sudden outbreaks from time to time in all parts of the country, and the rainstorm in Henan suddenly swept through, so we can only respond positively. All over the country, Qi Xin worked together to help each other in the same boat, and the difficulties passed. However, some human factors account for a large proportion in the occurrence of disasters, and we can avoid such incidents by paying more attention at ordinary times.

On the morning of July 23rd, a No.5 bus in Liling, Hunan Province spontaneously ignited. Fortunately, there were no casualties. Although the specific cause of the accident is still under investigation, the causes of bus spontaneous combustion are nothing more than these. First, the bus itself. Short circuit leads to spontaneous combustion, followed by man-made reasons. Passengers carrying inflammable and explosive articles or drivers driving improperly cause accidents. Third, external reasons. If the temperature is too high, the tire will spontaneously ignite when it rubs.

First, the bus itself. Now most buses are electric cars, so long-term use will wear out the circuit. If it is not overhauled in time and no line problems are found, a short circuit may occur during driving, leading to spontaneous combustion. If it is not an electric car, the damage to the fuel tank will also cause spontaneous combustion, so we must pay attention to maintenance and check and maintain it regularly to avoid disasters.

The second is spontaneous combustion caused by human factors. Passengers taking subways, high-speed trains, airplanes, etc. will be inspected. It is forbidden to carry inflammable and explosive articles on trains, subways and planes, but they will not be checked when taking buses. It is also possible that passengers carrying inflammable and explosive substances on the bus cause the bus to spontaneously ignite.

Third, external causes lead to spontaneous combustion. With the arrival of summer, the temperature rises everywhere, especially in the south, and the highest temperature can reach more than 40 degrees. As a public transport, the bus runs frequently, and the tires heat up in constant friction. Coupled with such high temperature weather, spontaneous combustion is easy to occur.
