|Decomposing Organic Matter Can Create a Hazardous Atmosphere in a Confined Space.|
|Decomposing organic matter, such as domestic waste and plant life, can produce Methane, Carbon Monoxide, Carbon Dioxide and Hydrogen Sulfide, and can consume existing oxygen.
Oxygen Deficiency – Oxygen can be consumed by bacterial action or displaced by other gases.
Combustible Gases – The produced Methane, CO or H2S can reach explosive concentrations.
Toxic Gases – Both Hydrogen Sulfide and Carbon Monoxide are life threatening gases.
