In a permit-required confined space entry, how many persons must be present?

• A. Three
• B. One
• C. Two
• D. Four

Answer: (A)

The requirement is about having a complete on-site staffing setup for permit-required confined space entry. You need the person who will enter the space, an outside attendant who can watch and communicate with the entrant, and an on-site entry supervisor who authorizes the entry and oversees safety. The entrant is inside the space performing the task; the attendant outside maintains continuous contact and is ready to summon rescue if needed; the entry supervisor ensures the permit is properly in place, safety procedures are followed, and rescue equipment and plans are ready. This combination provides inside access for the task, outside supervision, and a backup to coordinate any emergency response. Having only one or two people would leave gaps in supervision or rescue readiness, while more people than the minimum aren’t required to satisfy the basic safety requirement.
