A permit-required confined space entry is required for spaces with restricted entry/exit and potential hazardous atmospheres; entry requires a permit, continuous monitoring, and rescue readiness.

• A. For spaces used for open-top storage with no hazards.
• B. For spaces with unrestricted entry and exit and no hazardous atmospheres.
• C. For spaces with restricted entry/exit and potential hazardous atmospheres; entry requires a permit, continuous monitoring, and rescue readiness.
• D. For any space that does not require permit.

Answer: (C)

A permit-required confined space is defined by restricted entry/exit and the presence or potential for hazardous atmospheres, which means entry must be controlled with a formal permit, continuous atmospheric monitoring, and rescue readiness. The described scenario fits exactly: workers enter spaces that have limited ways in or out and that could contain dangerous gases or other hazards, so a permit is required, the atmosphere is continuously checked, and trained rescuers and equipment must be ready in case something goes wrong. The other descriptions don’t fit because spaces with open-top storage and no hazards don’t present restricted entry or hazardous atmospheres, spaces with unrestricted entry and no hazardous atmospheres aren’t confined spaces, and anything that doesn’t require a permit isn’t a permit-required space.
