Which statement best defines a confined space?

• A. An enclosed space not designed for people to occupy.
• B. A large, open area used for storage.
• C. A space that is always safe to enter without PPE.
• D. A ventilated area with no hazards.

Answer: (A)

A confined space is a place where entry is possible but not intended for people to stay in or work within for long periods, and where access is limited. The statement that best fits this idea is an enclosed space not designed for people to occupy. It captures the essential idea that the space isn’t meant for regular occupancy, even though someone might enter it to perform work. The other options describe spaces that aren’t confined (a large open storage area), or claim safety features that aren’t reliable in confined spaces (always safe to enter without PPE, no hazards), which isn’t accurate because confined spaces can be hazardous and often require PPE and precautions.
