1. Safety Guidelines for Operators Working On or Near Biogas Capture, Storage and Combustion Systems

The collection and handling of biogas is accompanied by a number of hazards, the most significant of which include:

  • toxicity of hydrogen sulphide gas (H2S);
  • flammability of biogas when mixed with air in specific proportions; and
  • suffocation due to the exclusion of air, especially in confined spaces.
