Is coal gas harmful to the human body?

Coal gas is a kind of gaseous fuel, which is mainly made from coal as raw material. Since gas is clean and efficient, many people use it as fuel for cooking and heating in their homes. Gas is indeed of great help to our lives. But gas can also be very bad for our body. So what are the hazards of gas to the human body? Let’s talk about it below.

Long-term exposure to low concentrations of carbon monoxide is also extremely harmful to the human body. It can cause a decrease in the function of the nervous system and lead to symptoms such as headache, dizziness, fatigue, insomnia, weakness, memory loss, etc. Pathological reactions often occur. Repeated poisoning may lead to brain cell death and ultimately permanent damage to the central nervous system.

1. Natural gas leaks can cause people to die from suffocation. The air that humans rely on for survival contains about 20% oxygen. If your activity space is a closed space with thin oxygen, you will lack oxygen, suffocate, and fall into a coma. People with cardiovascular and cerebrovascular diseases will be in danger of their lives. In a closed space, natural gas leakage will make the oxygen in the air relatively thin, which is naturally harmful. If encountering this situation, first close the main valve, turn off the power supply and fire source, and open the doors and windows to allow air circulation.

2. The main components of natural gas are alkanes (methane, ethane, propane, butane...) and a small amount of carbon dioxide and sulfur dioxide. Its combustible components are alkanes, which are colorless and odorless and will not poison people (they will only suffocate people). The sulfur dioxide in it has an odor. Usually, if there is very little or no sulfur dioxide in natural gas, a small amount of sulfur dioxide gas is added to it to make it easier for people to detect pipeline leaks by smell. Natural gas is not toxic like coal gas (carbon monoxide). Natural gas is non-toxic.

3. Another hazard of natural gas is explosion. The air usually contains a few percent of natural gas, which will explode immediately when encountering open flames, endangering the safety of buildings and human lives. Therefore, if you find a natural gas leak in the room, avoid open flames and cremation.

The hazards of gas to the human body are introduced above. If we can pay more attention to preventive measures and use gas correctly in normal times, it will be very good for our body. However, if preventive measures are not taken or gas is used incorrectly, it will be very dangerous to our health.
