What is a confined space, and name two common hazards associated with it.

• A. A space with limited means of entry or exit not designed for continuous occupancy; hazards include limited oxygen and a toxic atmosphere, engulfment
• B. An open-air courtyard used for storage
• C. An enclosed space with always full occupancy and no risk of oxygen deficiency
• D. An outdoor area with high temperatures and direct sunlight

Answer: (A)

A confined space is defined by having limited means of entry or exit and not being designed for continuous occupancy. This combination means it can be hard to get in or out quickly, and conditions inside aren’t meant for people to stay in for long periods. Two common hazards you’ll encounter in such spaces are a limited or deficient oxygen supply and the presence of a toxic or hazardous atmosphere. Engulfment is another risk when loose materials can fill or trap a person inside. The other options describe spaces that aren’t confined or ignore the occupancy and hazard realities typical of confined spaces, which is why they don’t fit.
