Recently, there have been frequent fire accidents in electric vehicles
In the history of safety production, the occurrence of safety accidents is always strikingly similar.
Recently, there have been frequent fire accidents in electric vehicles, and from the perspective of the size of electric vehicles and the possibility of accidents, there is its inevitability.
When I was a child, the tractor was the main means of transportation and agricultural tools, and I often heard that accidents caused by tractors occurred, and in the environment at that time, the laws and regulations of safety management and safety awareness were not high. So I found some accidents on the Internet that occurred with tractors and other agricultural vehicles in my childhood.
A farm tricycle overturned in an accident, killing 10 people and injuring six. A farm vehicle overturned in an accident, killing 14 people and injuring 13 others.
This also reminds me of when I was in high school, when some people rode on their own and grabbed the tractor bucket gang with one hand, which saved a lot of effort. At that time, there were few cars, and now it is very risky; At the same time, at that time, the teacher often emphasized that after school, do not hoist the tractor (crane tail), pull over, and let the car go.
At that time, the students went to school a long way, if they walked back from the town after school, it would take more than 2 hours, and they had to walk the mountain road, and it happened that the tractor went back and forth between the town and the village, and they were familiar with each other, and they didn't need money, many people would still go to hang the tractor or go to the tractor, this is no way, there is no better choice than this.
Even at that time, I saw a lot of people riding tractors, when I was a child, the village heard that a woman was crushed to death by a tractor, because she was not married, she could not enter the house, so she could only do things hastily outside the village. It happened to be near the elementary school, and I was scared for several days.
It can be said that at that time, the tractor not only became a freight tool for rural construction, but also became a means of transportation in the countryside, mixed loading of people and goods, and the safety factor was low.
Thinking about it this way, the electric vehicle fire accident caused now is similar to the accident caused by the tractor back then, why can't electric vehicles? Therefore, we must look at the current electric vehicle accidents rationally.
Why did this happen then, when it almost never happens again? This is "the productive forces determine the relations of production".
At that time, the productivity was dictated, and everyone was poor, so they had to choose this way, but now the productivity has progressed, the production relations have changed, and the tractor and other agricultural vehicles with a low safety factor have disappeared, and the old safety problems have disappeared, but then, new safety problems will arise.
This also further illustrates that science and technology are the primary productive forces, and also explains why we should follow the order of "elimination, substitution, engineering control, management, and individual protection" in the field of safety management.
Because technology is fundamental to solving security problems, we should start with technology first, and if it is the current low productivity or economic constraints, we will consider taking later measures.
Technology is improved, the problem of productivity is solved, the production relationship is improved, safety is integrated into the production and operation activities, the change of production relations, the old safety problem is adjusted or solved, and the new safety problem arises, just like the demise of the tractor.
In safety management, the real solution to safety problems is to rely on science and technology, the production of reliable batteries and electric bicycles, the gradual elimination of old electric vehicles, the implementation of the old to gradually improve the performance of the transfer vehicle. Hopefully it's getting better and better.
