Which is NOT a criterion to be a designated confined space?

• A. A room that locks when the door is closed
• B. Has limited or restricted means for entry and exit
• C. Not designed for continuous employee occupancy
• D. Is large enough and so configured that an employee can bodily enter it

Answer: (A)

The key idea is understanding what makes a space a confined space in the workplace. A space is considered confined because it has limited or restricted means of entry and exit, is not designed for continuous occupancy, and is large enough for a person to enter and work. The statement about a room that locks when the door is closed is not part of that definition. Locking a door doesn’t determine whether a space is confined; a space could have a locked door or an unlocked one and still meet or not meet the other criteria. What matters are the entry/exit restriction, the lack of design for ongoing occupancy, and the physical size to allow a person to enter.
