No one should enter a silo until 7 to 10 days after it is filled. Good ventilation above the base of a silo should be maintained during the 7- to 10-day period. The area should be fenced in to prevent children or animals from straying into the space surrounding a silo. An exhaust fan should always be activated before a person enters a silo.
Corticosteroids such as prednisone or methylprednisolone help prevent lung injury in patients exposed to silage gases.
