A person is trapped in a farm silo. This situation is considered which type of space?

• A. A confined space
• B. An open space
• C. A hazardous location
• D. An enclosed room

Answer: (A)

Confined space. The key idea is recognizing spaces with restricted entry or exit that aren’t meant for regular occupancy and can host hazardous conditions inside. A farm silo fits this because its opening is narrow and limited, the interior isn’t designed for people to work in for extended periods, and there’s potential for dangerous atmospheres or engulfment hazards from grain. It isn’t simply an open space, which would have easy access and egress, nor is it just an enclosed room, since the defining feature here is the restricted access and potential internal hazards that require special precautions.
