These incidents have resulted in several deaths and many more illnesses caused by exposure to poisonous gases. This does not include economic losses from animals that die from the gases. It is difficult to know when air quality problems will occur. The best precaution is to understand the sources of air quality problems, and what to do to reduce or eliminate them. This publication will discuss five common gases found in manure storage facilities, and other hidden dangers.
Gas builds over time, often rising to the surface and escaping into the air.
Enclosed livestock areas must be ventilated, even on cold winter days, to remove moisture and gases. Carbon dioxide is the result of animal respiration. Carbon monoxide is the result of using combustion equipment, such as heaters and gas-operated power washers, in a confined area. This equipment produces more carbon monoxide when engines don't burn cleanly. At high concentrations, carbon dioxide and carbon monoxide can cause respiratory distress and headaches.
