Sad! Although the tragedy in Leshan is due to biogas poisoning caused by pig grass fermentation, in my opinion, these incidents are ultimately due to carelessness and lack of safety awareness in people's lives. In fact, biogas poisoning is easy to understand. The composition of biogas is methane, and the principle of biogas poisoning and gas poisoning is the same. In my opinion, the Leshan incident can be completely avoided, but it really shouldn't be caused by the gourd dolls being given away by grandpa one by one in the later period. Knowing that the people in the cellar are poisoned clearly shows that toxic gases still exist under the condition of poor air circulation.

But they didn't rush in to save people without taking any anti-virus measures. I can only understand that they are eager to save lives. But there are many negative textbooks about this kind of thing in society. I often hear countless examples. I saw someone drowning and jumping into the sea to save people but forgot that they couldn't swim, which led to the death of both of them. But what I admire most is that this kind of thing happened around us and people still didn't learn a lesson at all.

It is not that biogas is so deadly, but that biogas itself is fatal after being inhaled by the human body. Every year, I hear countless safety accidents, large and small, but every time I just need to find these safety accidents, I find some small flaws, that is, accidents can be prevented and prevented in advance. I am the kind of person who often doesn't do things before they happen. I often take my chances on security issues. This may be because I don't take safety seriously when I don't do it myself.

Another point is that I find that we ordinary people lack safety awareness and knowledge of safety assistance, and we know nothing about self-help technology. For this reason, I think on the one hand, we don't pay attention to it ourselves, on the other hand, the publicity and training in this area may not be in place. I hope everyone can put safety first. After all, we represent not only ourselves in this society, but also our family and friends behind us.
