Confined-Space Manure
Ventilation Design Tool

Welcome to the Penn State College of Agricultural Sciences Confined-Space Ventilation Design Tool

Go back to the Manure Pit Safety page


This is an online tool that manure pit designers and field engineers can use to predict how long a confined-space manure storage needs to be ventilated before it is safe to enter. Airflow through the animal living space above (barn) is also simulated, and can be used to determine whether or not animals need to be evacuated from the barn during pit ventilation.
