Methane (CH4)
Natural gas – or methane (CH4) – is naturally produced from the decomposition of organic matter in poorly oxygenated areas. Its anthropogenic version is massively produced through the exploitation and combustion of fossil matter and in any other field of activity with organic matter decomposition: waste landfill sites, and biogas production.
Dangers of methane gas
Methane (CH4) is colourless, odourless and heavier than air. Because of these properties, this cannot be detected without proper equipment and can accumulate in suspended ceilings and other high-up areas. This gas is above all extremely flammable (R12) and explosive, with explosive limits between 5 and 15% volume.
Methane – CH4 gas – is not a toxic gas but it might replace oxygen when reaching high concentration levels in poorly ventilated areas. It is also responsible for the greenhouse effect as it absorbs the earth’s infrared rays that enhance climate warming. Methane is one of the six major gases covered by the Kyoto Protocol.
CAS-Number: 74-82-8.
