The explosion of Havana Hotel in Cuba has caused 18 deaths. What is the current situation of accident investigation?

The current investigation shows that the explosion was caused by natural gas leakage, which was related to the car that provided natural gas to the hotel. This hotel in Cuba, as a landmark building of19th century, is also one of the five-star hotels in the local area. However, the explosion not only completely destroyed some areas of the hotel, but also spread to a nearby school. The smoke and vibration caused by the explosion had a great impact on the local residents. So far, no China citizens have been injured in the explosion, but the number of local casualties in Cuba is still increasing.

1. Investigation shows that the explosion was caused by natural gas leakage.

According to the report of Cuban national television, it can be analyzed that this hotel should widely use natural gas, and there are natural gas tanks in the hotel. The explosion was caused by a truck carrying natural gas to a gas tank, but the news did not specifically show how the truck caught fire.

Second, there are three main reasons for natural gas leakage.

According to official statistics, natural gas leakage is mainly due to hose problems, improper use and human factors. The so-called hose problem, as the name implies, is that the pipeline is aging, falling off or being destroyed by the outside world. Improper use, intuitively speaking, means forgetting to turn off the valve after use at home, and human reasons include some illegal modification and operation.

Three. Matters needing attention in natural gas leakage.

Although the hotel explosion in Cuba is an unpredictable situation, at home, we should take some preventive measures against natural gas leakage. At present, the domestic natural gas has been odorized, so that people can feel it at the first time of leakage. Once the air smells, it is necessary to check whether the natural gas source can be turned off or cut off at the first time, and then quickly open the window for ventilation. At the same time, it should be noted that it is forbidden to make phone calls and turn on and off lights, because electric spark or static electricity is one of the three major factors leading to natural gas explosion.
