Is inhaling methane gas harmful?
Methane is non-toxic and poses no hazard when inhaled in limited amounts; However, when large amounts of natural gas or methane displace the air, lack of oxygen can cause asphyxiation.
High concentrations of methane canreduce the amount of oxygen inhaled from the air. This can cause mood swings, slurred speech, blurred vision, memory loss, nausea, vomiting, facial flushing, and headaches. In severe cases, there may be changes in breathing and heart rate, impaired balance, numbness and loss of consciousness.
- Rapid breathing.
- Increased heart rate.
- clumsiness and dizziness.
- Decreased vision, especially in low light conditions.
- Euphoria.
- Decreased attention.
- memory loss.
- Weakness.
The Dangers of Hydrogen Sulfide, Also Known as "Sewer Gas"
A naturally occurring gas, hydrogen sulfide or “H2S” is toxic in high concentrations. Prolonged or acute exposure to the gas can cause eye irritation, headaches, nausea, fatigue and, in extreme cases, death.
Suffocation.High levels of methane in enclosed spaces can cause asphyxiation, since large amounts of methane reduce the oxygen content of the air. The consequences of lack of oxygen are headaches, nausea, dizziness and unconsciousness.
methane is aodorless, colorless, flammable gas. It is mainly used as a fuel to generate heat and light.
Methane gas is naturally produced by sewage sludge, while nitrate is a by-product of a failing sewage treatment system.These fumes can be released back into your home through toilets, pipes and drains, putting your family at serious risk.
Gas produced by the rotting of human waste is a potentially important energy source, powering millions of homes while improving sanitation in developing countries, a UN report says.Biogas - about 60 percent methane - can be produced by bacteria breaking down human feces.
Methane SIBO is initially treated by working to reduce the overgrowth of bacteria in the small intestine. Treatment may include a combination ofDietary changes, use of antibiotics, probiotics and prebiotics. It is also important that the underlying problem is treated.
Health Effects
The Occupational Safety and Health Administration (OSHA) does not have an allowable exposure limit for methane, but the National Institute for Occupational Safety and Health (NIOSH) recommends the maximum safe concentration of methane for workers during an 8-hour period1,000 ppm (0.1 percent).
How long can you be exposed to methane?
Even a one-minute exposure to a high concentration of methane gas in a sealed room was enough to cause unconsciousness.
