The probability of sewer safety accidents can be said to be very high, and many people are familiar with such incidents. In Chongqing, there was also a case in which a sewer pipe caused a person to die. At that time, three workers were cleaning up the stains in the pipeline, but the long-term accumulation of dirt in the sewer pipe produced some toxic gases, which were accidentally inhaled during the treatment, leading to poisoning. Although rescuers arrived in time, two of them were killed. Therefore, seeing this situation, it is inevitable that some people will feel very sad and distressed. After all, these things can be avoided artificially, but due to their negligence, these events happen frequently.
Secondly, in many short videos, we can also see that some people often bend their heads to play with their mobile phones or look around when driving on the road, resulting in not noticing that the manhole cover in front of the sewer pipe was not properly closed and accidentally fell in. Most of them may have been washed away by the current in the pipeline after falling, and many bodies can only be found in sewage treatment plants.
This little boy in Qingdao was killed for this reason, so we must pay more attention when walking on the road. Parents also need to establish safety awareness for their children, so that children can realize that the shape of the road is very dangerous. Don't trample on the manhole cover casually, otherwise they may fall into the well bottom because the manhole cover is not completely covered, putting themselves in danger and bringing very sad and painful situation to their families.
