is large enough for an employee to enter fully and perform assigned work
has a limited or restricted means of entry or exit is not designed for continuous employee occupancy6

Permit-Required Confined Space – has one or more of the following: Contains or has the potential to contain a hazardous atmosphereContains a material with the potential to engulf someoneHas an internal configuration that might cause an entrant to be trapped or asphyxiated by inwardly converging walls or by a floor that slopes downward and tapers to a smaller cross section
Contains any other recognized serious safety or health concerns7

Slide18Hazards Related to Agricultural
Confined Spaces
Asphyxiation due to exposure to toxic environments
Carbon DioxideMethaneHydrogen Sulfide (manure)Ammonia (manure)Smoke/Carbon monoxide (fires)Suffocation due to oxygen limited environmentsEntrapments requiring extrication from flowable agricultural materialsEngulfments – fully buried in flowable agricultural materialEntanglements in energized machineryFalls
ElectrocutionsDrowningRespiratory distress due to exposure to dust and microtoxinsBurns from fires and explosions18
Slide19Relevant Federal OSHA Standards
29 CFR 1910.146 – Permit-required confined space standard
Exempts agriculture
29 CFR 1910.272 – Grain handling standardCovers all commercial grain storage and handling operationsOriginal focus on preventing grain dust explosionsExempts farms, feedlots, and seed processing operations19
Slide20Exempt Facilities
20
The OSHA Grain Handling Standard (1910.272) currently exempts from compliance certain farming operations:
Farms with 10 or fewer employedFeedlotsOperations that prepare seedsfor future cropsThe OSHA Permit-required Confined Spaces Standard (1910.146) generally exempts agricultural operations that:Grow or harvest cropsRaise livestock or poultry
Slide21Non-Exempt Facilities Must Have
Confined space entry permit system
Appropriate confined space entry equipment
Lifeline and harnessesAir monitoring equipmentCommunication systemEmergency action planDocumented trainingIncident reporting policies in place21
