▼a Current manure pit-safety ventilation research has been limited to determining the minimum amount of time required to evacuate hazardous gases to allow human entry into confined-space manure storages. Commonly installed negative pressure pit ven |

▼a Hydrogen sulfide (H2S) gas decay was measured at several locations inside a swine nursery room during manure pit and room ventilation. A computational fluid dynamics (CFD) model of the nursery room was developed, and transient simulations of pit |

▼a A trend observed during analysis of CFD simulation results for a given pit and barn shape and ventilation configuration (the same pit-safety fan location and flow rate with the same barn ventilation rate) with different uniform initial manure pi |

▼a Simulations were performed for a 12.20 m wide x 30.49 m long (40 ft wide x 100 ft long) barn located above a full-sized manure pit with a fully-slotted cover. Tunnel ventilated and mechanically cross-ventilated barn configurations were studied t |

▼a The tunnel ventilated barn was divided lengthwise into five 6.10 m long x 12.20 m wide (20 ft long x 40 ft wide) quintiles for analysis. For the tunnel ventilated barn simulated in this study, animals should always be evacuated from the quintile |
