Since the early 1960s, nearly 150 people have died in the U.S. because of manure-related gas incidents in confined spaces (NCERA 2016). Of those cases, about half occurred on dairy operations. Almost 25% involved a young person under the age of 16. The most common activity at the time a person died was conducting repairs or maintenance on manure handling equipment (34% of the deaths) followed by actions associated with trying to rescue another person entrapped or overcome in a manure storage/reception pit (22% of deaths, Beaver & Field, 2007).
In Reducing Risks from Manure Storage Agitation Gases, UW-Extension specialists share the common gases released during manure agitation, the conditions that increase risk related to manure gases, and recommended safety practices.
