SILO GAS

One of the deadly gases that many Wisconsin dairy farmers encounter each year is silo gas, or, nitrogen dioxide. Silo gas forms a few hours after filling any type of silo, but it is especially an issue with tower silos. Silo gas is heavier than air, has a yellow-brown hazy appearance, and smells like bleach. Stay out of a freshly-filled silo and surrounding areas for at least two weeks after filling. When it is safe to enter, run the blower for at least an hour to assure that the gas has been removed and that there's a fresh supply of clean air.
