The hazards of methane

What is methane? Methane is one of the simplest hydrocarbons. It is widely found in natural gas, biogas, and coal mine pit gas. It is a high-quality gas fuel and an important raw material for the manufacture of synthesis gas and many chemical products.

Toxic and harmful gas detector-Methane is normally colorless, odorless and non-toxic, and it is a flammable gas that is easily soluble in water. However, if the methane concentration in the environment is too high. The oxygen content will be significantly lower, which will cause breathing disorders and lead to suffocation. When methane in the air reaches 25%-30%, it can cause headache, dizziness, fatigue, inattention, accelerated breathing and heartbeat, and ataxia. If you don't stay away in time. It can cause suffocation and death. Skin contact with liquefied methane can cause frostbite.
