Safety in Composting Halls: Managing the risks from Carbon Monoxide

Johnson, David N. and Howell, Graham (2018). Safety in Composting Halls: Managing the risks from Carbon Monoxide. Chartered Institution of Wastes Management (CIWM).



The importance of fitting the correct sensors for carbon monoxide monitoring in enclosed composting facilities has been highlighted by recent research conducted by the Open University, in collaboration with Amey Ltd. The research was commissioned due to concern about the frequency of alarm activations from carbon monoxide personal safety monitors within the composting facility of an MBT (Mechanical Biological Treatment) plant. Further investigation confirmed the presence of carbon monoxide in the compost hall, though at levels below the 30 ppm alarm threshold. However, nonhazardous levels of hydrogen were also present and caused interference to gas safety monitors, leading to false alarms for high carbon monoxide.
