Inhalation of natural gas can be toxic.
Natural gas is mainly composed of methane and a small amount of ethane, propane, nitrogen and butane. When natural gas leaks, it mainly enters the human body through the respiratory tract, and when the concentration is high, it will cause a lack of oxygen in the human body, resulting in shortness of breath, loss of consciousness, and in severe cases, death due to asphyxiation.
Inhalation of a certain amount of natural gas can lead to poisoning, and common symptoms include headache, dizziness, fatigue, nausea, vomiting, coma, limb straightening, and respiratory difficulties. After being poisoned, you should immediately move away from the area of the natural gas leak to a well-ventilated place, get enough rest, and contact a hospital for help.
When using natural gas on a regular basis, it is important to take precautions and check the natural gas pipeline regularly.
