Event Review: An explosion occurred in the tanker of Liangshan Village Expressway in Daxi Town, Wenling City, Taizhou City, Zhejiang Province, causing more than 120 injuries. Take the explosion of a tanker in Wenling, Taizhou as an example. It was a tanker loaded with liquefied petroleum gas. It exploded at G 15 Shenhai Expressway and also rushed out of the expressway, causing damage to surrounding factories and houses, causing at least 127 people to be injured, and several adjacent expressways. After the incident, more than 450 firefighters also arrived at the scene for rescue work.
Looking back on the previous dung truck explosion and other tanker explosions, and the huge damage caused, we will find that the tanker is a walking killer, and its accident causes are nothing more than the following three:
0 1, the oil-gas ratio inside the tanker is high, and it will explode when it encounters static electricity or open flame. First, when the oil and gas in the tanker rises to a certain concentration, it will be quite easy to be detonated. At this time, if you encounter static electricity or open flame, it will produce a terrible explosion.
In order to prevent open flames, it is generally forbidden to set off fireworks and firecrackers on vehicles. Drivers are not allowed to smoke, carry lighters or wear shoes with nails. Hanging fire? Frequent use is also prohibited by law. In addition, the car also needs to be equipped with a special fire extinguisher.
In order to prevent static electricity, an iron chain will be dragged at the bottom of the tanker, which will drag the ground to release static electricity generated by tires rubbing the ground for a long time. In addition, when the vehicle is refueled or drained, the pole will be inserted into the wet ground to ensure the safety of the vehicle.
So as long as the operation is standardized and there are no special accidents, static electricity and open flames can be completely prevented.
(One point that needs special attention: even if the tank truck empties the oil in the tank, there will still be a lot of flammable and explosive gases left in the tank. This kind of vehicle is still very dangerous. If the driver wants to repair the vehicle, he must find a regular and reliable maintenance unit to avoid tragedy. Passers-by also need to stay away from the tanker under maintenance. )
02. The safety training for drivers by transportation companies is not in place, and drivers have no corresponding safety awareness. Some transportation companies have weak safety awareness. In order to save time and money, they did not organize formal and systematic safety training and related risk warning education, which led to drivers' lack of corresponding safety awareness and emergency handling ability.
Individual tanker drivers have no knowledge of safe operation, and some are lucky enough to secretly engage in illegal operations, such as not cleaning and maintaining spark plugs in time, but using them for a long time? Hanging fire outside the cylinder? , so that vehicles have potential safety hazards, and accidents are more likely to occur in high temperature, thunderstorm or dry weather.
03. There are frequent traffic accidents such as tank trucks, cement mixers and muck trucks, and the accident rate is about 30 times that of other vehicles. According to the annual traffic accident analysis, it will be found that large vehicles such as tank trucks, cement mixers and muck trucks are more prone to traffic accidents, and their accident rate is basically 30 times that of other vehicles. The drivers of these vehicles are also high-risk industries, which can be said to be driving with their lives.
The cause of the accident is that the tank car has a large mass and inertia, and it is difficult to drive such vehicles, which consumes the driver's energy very much. In addition, it is difficult to get a driver's license for a tanker, and few drivers can replace it. Some drivers are tired of driving in order to make more money, and they are more likely to have traffic accidents if they can't smoke to refresh themselves.
In short, everyone's life is not easy. To understand the hard work of tanker drivers, every driver is required to improve safety awareness. Pay more attention to avoiding tanker trucks every day. We only have one life, and we hope that the fewer similar incidents, the better.
