What is the main reason for the explosion of Shiyan major gas accident 4 minutes after the emergency repair?

This time, the safety accident can be said to have aroused great concern of the people of the whole country. Up to now, the investigation of this matter has finally come to the bottom, and the State Council has also given the corresponding accident investigation report. The accident investigation team determined that this explosion accident was obviously a safety responsibility accident. Today, I will discuss with you what factors led to the subsequent explosion in this accident.

first, the direct cause of the accident.

The main reason for this accident is that some serious corrosion of the medium-pressure steel pipe transporting natural gas has not been solved, which leads to the leakage of natural gas. After the leakage, the natural gas is stored in the closed space of pipelines and rivers under closed buildings for a long time. And it happened to be connected with the oil smoke pipes of some merchants above. After encountering Mars, there was a violent explosion, which led to this accident.

second, the indirect cause of the accident.

during the investigation by the investigation team, it was found that this was mainly because the staff responsible for pipeline operation and maintenance had never inspected the accident pipeline for such a long time. After the incident, in order to escape his responsibility, he chose to falsify the inspection record. So as to cover up his own mistakes, but obviously, his efforts were easily exposed by the investigation. In this accident, 11 people who are currently in charge of safety have been investigated by the public security organs.

thirdly, what are the details of this explosion?

The reason why this explosion accident can arouse people's heated discussion is that, in addition to causing a large number of casualties and serious economic losses, the most important thing is that the emergency repair personnel of the gas company just left the scene and exploded four minutes later. The main reason is that although they solved the problem of natural gas leakage, they did not solve the problem of natural gas stored in closed spaces.
