What is the role of an attendant during confined-space entry?

• A. Administer medication to entrants
• B. Record the duration of the entry only
• C. Operate machinery outside the space
• D. Monitor entrants, maintain communication, ensure rescue readiness, and halt entry if hazards arise

Answer: (D)

The person outside the space acts as the safety monitor for anyone entering. The key role is to watch the entrants, stay in constant communication with them, be ready to summon or coordinate rescue if anything goes wrong, and have the authority to stop the entry if hazards develop.

Monitoring entrants means keeping an eye on their condition and progress, noting signs of distress, fatigue, or equipment trouble. Maintaining communication ensures the entrant can report issues immediately and follow any precautions or changes in procedures. Ensuring rescue readiness means having the rescue plan and equipment prepared, and being ready to activate it or call for outside help at a moment’s notice. The ability to halt entry is crucial—if atmospheric conditions change, if a hazard is detected, or if the entrant signals danger or becomes incapacitated, the attendant must immediately stop the entry and evacuate everyone.

These duties keep the operation safe because the attendant serves as a dedicated, outside observer who can coordinate a timely response without being inside the space themselves. The other descriptions don’t capture this full, protective role.
