Which of the following defines a confined space?

Which of the following defines a confined space?

• A. is large enough and so configured that an employee can enter and perform assigned work
• B. has limited or restricted means of entry
• C. all of the above inclusively
• D. is not designed for continuous employee occupancy

Answer: (C)

Confined space is defined by three key features: it must be large enough for a worker to enter and perform work, it must have limited or restricted means of entry or exit, and it is not designed for continuous occupancy. The best choice is the one that includes all three criteria because a space only meets the definition if every element is present. If any one of these elements is missing—for example, a space that’s large but has unrestricted entry or is designed for continuous occupancy—it wouldn’t be considered a confined space. Similarly, a space with restricted access but too small to work in wouldn’t qualify. So the correct choice is the option that states all three conditions.
