Confined spacesWhat all agricultural workers need to know
What is a confined space?
• Enclosed• Worker can get inside• Not intended for occupancy• Difficult to evacuate or rescue
2
Grain bins
• Toxic gases• Low oxygen• Engulfment (by grain)• Bacteria and moulds• Mechanical equipment (augers)

• Mechanical parts
(cleaning wands,
agitators)• Toxic gas
(from cleaning chemicals) 4
Manure pond • Toxic gases• Low oxygen• Drowning• Bacteria and moulds• Moving machinery
(agitators and pumps)5
