What is it?
Methane is a colorless and extremely flammable gas that can explode when mixed with air. It is the primary component of natural gas.
Natural sources of methane include termites, bodies of water, wildfires, and digestive processes of animals. Methane is released from coal deposits during underground and surface mining and from decomposition of waste.
Methane is a greenhouse gas that contributes to climate change.
Where is Methane found?
- Air – from vehicle exhaust, oil and gas fields, coal mines, coal-fired power plants, landfills, and farms
- Consumer products – water heaters, stoves, and clothes dryers that are fueled by natural gas
How can I be exposed to Methane?
Methane commonly enter(s) the body through:
- Breathing vehicle exhaust and emissions from farms, landfills, and use of fossil fuels
- Touching liquefied methane
What happens when I am exposed to Methane?
Skin contact with liquefied methane can cause:
- Skin and eye burns
Exposure to high levels of methane can cause:
- Loss of consciousness
- Headache and dizziness
- Nausea and vomiting
- Loss of coordination
- Increased breathing rate
Who is at risk for exposure to Methane?
- Everyone is exposed to low levels of methane in outdoor air. Some home appliances may emit methane.
