Manure Gases

People entering manure pits without taking proper precautions are at risk of dying from high exposures to hydrogen sulfide gas. Guidance on manure pit operations from ASABE specify the need to monitor these spaces prior to entry. These fact sheets provide guidance on the risks of entering manure storage pits, why and how to monitor for manure gases, and information about foaming manure pits.  The videos are from a special session on Pit Foam and Producer Safety at the 2016 Iowa Pork Congress in Des Moines, IA.
