What are the signs before the gas explosion?

At present, there are two kinds of natural gas channels used by everyone, one is liquefied gas cylinders and the other is gas pipelines. In fact, many natural gas explosions can be seen, and there are signs before the disaster, such as the following situation.

The first type uses liquefied gas cylinders, and the cylinder body expands. Because natural gas is in a steel cylinder, if the natural gas inside is likely to explode, it will definitely expand and spread the flat body. So if the liquid natural gas bottle you use has obvious expansion, turns black and shines, it is very likely to explode. We must stop using it and ask the relevant departments to solve this problem.

The second is that the flame turns white and hisses. Under normal circumstances, natural gas combustion is a blue flame without much noise. When you use natural gas, you find that its flame color changes from orange to slightly white, and its sound changes from "whistling" to slightly "hissing". This situation shows that there is a possibility of natural gas leakage, which indicates that it is about to explode. When the flame and sound change for 5 to 10 seconds, the sound and flame suddenly disappear and an explosion may occur at any time. Because this is not because her condition has improved, it may be caused by poor contact and so on.

The third is that the lying liquefied gas cylinder is burning. When using liquefied gas, be sure to pay attention to the fact that the cylinder cannot lie down. When using liquefied gas, many people like to shake it, even the whole cylinder is lying down, thinking that shaking liquefied gas can last a little longer, but this is a very dangerous move. Especially lying burning cylinders, because they are very likely to explode at any time. So when you see a burning cylinder lying down, don't touch it. Compared with the upright burning liquefied gas cylinder, the lying explosion is much bigger.

The fourth is that liquefied gas is in a high temperature state for a long time. Especially in some roadside stalls, when liquefied gas is used, the steel cans will be baked at high temperature for a long time, which is easy to cause the aging gas of the tanks to expand, some of which are direct physical explosions, and some liquefied gas will radiate into the air to cause chemical explosions. No matter where it is, it is because liquefied gas is in a high temperature state, so if it is found that the temperature of liquefied gas cylinders is high, it may explode.

Although the use of natural gas has brought a lot of convenience to our production and life, it has also brought some threats. Everyone must pay attention to these omens when using natural gas. Once found, you should save yourself and call the police in time to avoid those tragedies in the news.
