Manure storage and handling can create serious gas hazards for agricultural workers. As manure breaks down, gases including ammonia (NH₃), hydrogen sulfide (H₂S), methane (CH₄), and carbon dioxide (CO₂) can accumulate. These gases can become especially dangerous during manure agitation and pumping.
According to Michigan State University Extension, hydrogen sulfide is one of the most serious hazards associated with manure, while ammonia can cause irritation to the eyes and respiratory system. Proper ventilation, safe work practices, and gas monitoring are important steps in reducing exposure.
Monitoring Ammonia and Other Gases
For agricultural environments where ammonia is a concern, the BX403 NH3 Multi-Gas Monitor provides portable monitoring of four gases:
- NH₃ (Ammonia)
- CO (Carbon Monoxide)
- O₂ (Oxygen)
- LEL (Methane)
The BX403 features a built-in pump, audible, visual and vibration alarms, data logging, and a rugged IP66 enclosure. It is designed for applications including agriculture, food processing, and refrigeration.
Gas monitoring should be used as part of a complete safety program. Workers should always follow proper procedures when working around manure storage, pits, and confined spaces.
