It's that time of year again when fall manure spreading is occurring following the removal of corn silage. These fields are good candidates for cover crops and getting storages empty ahead of winter.
However, we need to be aware of some of the risks associated with hauling manure. Particularly those that we can't see.
That's right, we're gonna talk about gas... 🤢
💨 Methane is colorless, odorless, lighter than air and highly flammable.
💨 Hydrogen sulfide is colorless, smells like rotten eggs and is heavier than air. (Responsible for the most deaths).
💨Carbon dioxide is colorless, odorless, and heavier than air.
💨Ammonia is colorless, has a sharp odor and while not as deadly as the other three, can cause long-term issues from extended exposure.
Important tips:
🚫Do NOT try to rescue a person impacted by a manure gas incident (same goes for silo gas). Proper equipment is needed to prevent more exposure risks.
‼️Listen to your body for signs of gas exposure: eye irritation, dizziness, headache, shortness of breath, nausea, or coughing. If you "don't feel right", leave the area!
✔️Wear a gas monitor. Preferably one that also measures oxygen levels.
✔️Proper ventilation is important, particularly in the confined spaces of manure storages.
