What is the explosive range of methane levels in landfills?

The explosive range of methane levels in landfills is between 5% and 15%. This range is significant because it defines the concentration limits where methane could potentially ignite in the presence of an ignition source, leading to an explosion. Methane is a flammable gas that can accumulate in confined spaces, often resulting from the anaerobic decomposition of organic materials in landfills. Understanding this explosive range is crucial for safety management and ensuring that appropriate monitoring and control measures are in place to prevent accidents. This knowledge is particularly important for environmental health and safety professionals who work in areas related to waste management and landfill operations.
