Exposure to fungus from moldy grain can result in allergic reactions, characterized by chills, high fever, swelling, vomiting, dizziness and shortness of breath. The lungs can fill with fluid and collapse. An approved dust mask that fits tightly around the mouth and nose area effectively protects you from fungus present in moldy grain. If you choose not to wear a mask, there is a good chance you will have an allergic reaction and have breathing problems the rest of your life. Another potential health hazard exists during and after fumigation of a grain bin.
Fumigants are toxic to humans when inhaled, swallowed, or absorbed through the skin.
If you follow safety procedures, you can eliminate the potential for poisoning. Observe and follow all label recommendations. Selecting and fitting the proper gas mask and canister and using them correctly will protect you. Post warning signs alerting people to the dangers of fumigation. Always run the ventilation fan before entering the bin to ensure that the environment is not immediately dangerous to your life and health.
