On the basis of 13' s search and rescue of 12 victims, 14' s early morning 18: 30 to 14' s early morning, and 14' s early morning/9: 00, and 2 people were searched and rescued at noon14.
The on-site search and rescue is still going on. Up to now, this accident has caused 25 deaths, * * * a total of 38 patients/kloc-0 (including 37 seriously injured) have been treated, and the on-site search and rescue is still going on.
What may be the cause of gas explosion in Shiyan, Hubei Province? When people talk about the serious casualties and property losses caused by gas explosion, they also have doubts about the "suddenness" of the incident itself. The first message I saw on the Internet was that the gas pipeline network was being maintained in this area. Some people will inevitably associate accident responsibility with improper construction.
At present, the detection methods are all on-site detection. Every once in a while, the staff of our community gas supply company will come to check whether the pipeline is safe, whether the valve is normal and install an alarm. When the leaked gas reaches a certain concentration, it will automatically give an alarm. If there is leakage, it is necessary to open the window for ventilation to reduce the concentration, and close the main valve until the maintenance personnel come to the door for maintenance.
The main reason is the aging of gas pipelines. The second floor of the first row in Shiyan, Hubei Province was blown up beyond recognition. Through this explosion site, it should be considered that the gas pipeline in the basement leaked and exploded when it met an open flame. After the gas leaks, it will float up because it is light. If there is good ventilation, there will be no explosion accident in general.
There is no doubt that the gas explosion was caused by man-made disasters. First of all, gas explosion must have a premise. The gas pipeline is a low-pressure pipeline and will not explode by itself. The explosion is caused by gas leakage. It stays in a relatively closed space and reaches a certain density. Coupled with an open flame, it is indispensable to want gas explosion. These conditions are also the contents of daily inspection by gas company personnel. If the market inspection is in place, it is impossible to explode if the user does not use it and does not violate the rules. The final inspection result depends on which party is absent.
Because the explosion site is an old residential area, the infrastructure in the old residential area is relatively poor, and some gases may age. Whether there is a problem in gas management, which leads to the accident, or whether the pipeline is crushed by vehicles, which leads to a large amount of gas leakage, or whether the gas valves in residents' homes are not properly connected, which leads to the accident, we need to seriously investigate and analyze to find out the reasons.
