What toxic gas poisoning!! What's going on!
If the above ambient air contains a high concentration of methane, so that the oxygen content decreased, it will lead to suffocation, serious will lead to death. If the content of methane in the air to 25--30% will make the occurrence of headache, dizziness, nausea, inattention, incoordination, fatigue, weak limbs and other symptoms. If the concentration of methane in the air over 45--50% will be due to severe hypoxia and dyspnea, tachycardia, coma and suffocation.
. When inhaled methane excessive, toxic gases by alveolar quickly into the blood, combined with red blood cells, forming carboxyhemoglobin, ability to lose hemoglobin oxygen transport, causing hypoxia, while inhibiting respiration, leading to a series of symptoms of central nervous system
Biogas is a mixture of gases, mainly composed of methane, carbon dioxide, nitrogen, hydrogen, carbon monoxide and hydrogen sulfide. Methane (CH4) also known as the "gas", is colorless and odorless, is the main component of natural gas, coal gas, widely exists in natural gas, coal gas, biogas, silt ponds and closed pit ponds, wells, coal mine (PIT) and harmful gas in one of coalhole
