- Fire caused by overloading electricity: this is an extremely common cause of fire and explosion accidents. Overload is a condition in which load devices have too high a power consumption, higher than the rated voltage of the wires and power sources, causing switching devices to lose their ability to operate.
- Currently, the situation of overloading electricity often occurs in industrial parks, factories, plants, and workshops, when too many machines are operated at the same time, the power supply cannot meet the requirements. The electricity consumption needs of those types of machines will gradually cause overload, and electrical equipment working at excess capacity will explode.
- Fire due to short circuit: this is an incident that often occurs if the electrical area is not well managed in terms of conductor materials. Fire due to short circuit occurs when we use two ends of wire connected to each other or connect to electrical equipment not according to regulations, when the wires lose their insulating coating...At that time, the situation A short circuit will occur, possibly on a small scale, not causing much loss, but if a large number of non-standard wires are used, the short circuit will spread, taking place in the entire area. using electricity and damaging surrounding machinery and equipment, more seriously causing electrical explosions and fires that are very dangerous for humans.
- Fire due to static electricity: this is also one of the causes of electrical fires and explosions. Fire due to static electricity is understood as when static electricity is formed by friction between conductive objects and insulators, the Collision of liquids with metal can also cause fire and explosion.
- Fire due to electric arc: electric arc is a form of electrical discharge with extremely high temperature, its temperature can be up to 6000 degrees Celsius, fire due to electric arc often occurs in electric welding.
- Fire due to heat transfer and heat emission of electrical appliances: during use, electrical appliances often emit heat, if there are no measures to properly adjust or control the power source. When the heat is released, there is a risk of fire and explosion. In particular, some devices operate at extremely high capacity, their heat source is extremely dangerous.
