Gas Leakage May Take Life Of People

Liquefied petroleum gas, which we also often called the coal gas, is a kind of fuel that many families choose to use. But what we should pay attention to is that the CO coal gas contained will make people poisoned. Carbon monoxide is the main component of coal gas. It can combine with hemoglobin, which will not only reduce the ability of carrying oxygen of blood cells, but also suppress and delay the analysis and release of oxygen hemoglobin (O2Hb), causing body tissue necrosis. If not received timely detection and treatment, people will die because of suffocation. Furthermore, when the content of gas in the air reaches 2% to 10%, there may be an explosion once it meets flame or spark. And this is why we need to install gas detector at home.

Reasons for gas leakage are mainly divided into six types. The hose connecting the stove is aging and cracking or its two ends are loosing. The failure of the ignition makes gas without complete combustion directly discharge. The boiling soup or water extinguishes the fire or the wind blows out the fire. Off the fire, stop valve of the stove is not closed completely. Now the tragedies due to gas leak still usually occur, so the gas detector equipment is really necessary. Gas detectors can detect gas leaks, providing guarantee for the safe use of household gas.

Harm Of Natural Gas Leakage

Natural gas is an important energy, which has been widely used as a city gas and industrial fuels, but when the natural gas in the air reaches a certain extent, it may cause asphyxia. Natural gas is not toxic, and it is essentially harmless to the human body. But if natural gas is in the state of high concentrations, there will be not enough oxygen in the air to sustain life, which will cause a person's death. After all, natural gas can not be used for human breath. In addition, as the fuel, natural gas will cause casualties by explosion.

Although natural gas is lighter than air and is easy to diverge, but when natural gas accumulate in the house or other closed environment and reaches a certain proportion, it will trigger a powerful explosion. The explosion may level the entire house, and even bring disaster to the neighboring buildings. By the way, the explosion lower limit of methane in air is 5%, and the upper limit is15%.

In view of the harm of above leakage of natural gas, in order to monitor whether there is a gas leak and to protect our life safety, gas detector has become the necessary safety equipment. Gas detectors can alert people in the initial stage of natural gas leakage, which will be helpful to prevent the happening of accidents.
