Why did Jinan bus explode? Is it too hot?

This bus should be a diesel car. It should contain volatile substances, such as alcohol, gasoline and some solvents. In summer, when the air-conditioning window is closed and the volatile substances in the compartment reach a certain concentration, the spark contacts with the electrostatic automobile electrical appliances in the compartment, which easily ignites the mixed gas in the compartment, leading to heating, deflagration and explosion.

3. Don't put flammable items in the car in summer;

Lighter: Ordinary lighters are mainly liquid butane, which is flammable and explosive. High concentration butane will explode at room temperature and 20℃. When the ambient temperature of the lighter exceeds 55℃, its volume will expand. When the outdoor temperature exceeds 30℃, the indoor temperature will be as high as 60℃ and 70℃ after exposure, which will easily lead to explosion accidents. Car perfume: The product with sealed bottle body is easy to explode when the high-temperature inflation gas cannot be discharged. In particular, crystal glass perfume bottles can form a focusing effect similar to a magnifying glass in the case of sunlight. If we focus on flammable materials, it will be dangerous. Be careful not to put perfume in the car in summer.

Underground garages and shady places are the first choice for parking in summer. Underground garages generally have an exhaust system, which will not be exposed to the sun and the car will not be too hot. For car owners who don't have parking spaces, try to find a shady place, such as in the shade of trees or buildings, but don't park illegally.
