What should we do at the first time in case of gas leakage? It is often seen that there is a fire or death event caused by gas leakage, and gas has become an 'invisible killer' that may kill people at any time. Xiaobian reminds us that the most important thing is not to turn on the switch at will in case of gas leakage!
What measures should we take when we find out the gas leakage? It's good to have some basic knowledge at ordinary times.
In middle school chemistry class, you must have learned that when H2 and O2 are mixed, they will explode (and form water) when they encounter Mars or fire. This is because when hydrogen and oxygen mix with Mars, they will burn rapidly and generate a lot of heat. A large amount of heat in a short period of time will make the air expand rapidly and explode.
Gas is mainly composed of H2, including 50-55% H2 and less than 45-50% Co, CO2, a small amount of H2S, methanol and benzene. There is a certain concentration of oxygen in the air. So when the gas leaks and reaches a certain concentration, it will explode when encountering fire (star). In addition, the consequences of a large number of gas leakage are: the content of oxygen in the unit volume is reduced, causing people to lack oxygen, which is life-threatening. The high heat produced by combustion burns people; the oxygen in the air is consumed quickly during combustion, which makes people suffocate.
Treatment of gas leakage
When gas leakage is found, in order to prevent its serious consequences, don't panic when you can't leave the house quickly. You should start from two aspects: first, reduce the gas content in the air; second, prevent the fire. For the former, quickly open all the doors and windows in the home to make the air circulate, and then close the gas valve; for the latter, when the gas leakage is found, do not move various power switches. In particular, when people wake up at night and find gas smell, they are used to turning on the light first when they get up. At this time, they must not turn on the light. Because when you switch on and off the power switch, there will be sparks. At this time, there are a lot of gas in the room and in the switch, so the consequences can be imagined. In the same way, when the light is on, you can't turn off the switch if you find gas leakage. Finally, call the relevant departments to find out the cause of gas leakage.
