Answers to the Quiz:
1. D. All are part of the definition of a confined space.
2. D. (Note, some work places may have more strict rules than OSHA and can identify all confined spaces as permit required.)
4. B. Although any site or work place can require an attendant at all confined space entries.
5. C. This would distract the authorized attendant from the stated purpose of attending to the entrant’s safety at all times.
7. Statistically, more fatalities occur to the would-be rescuer, who is probably not part of a trained, experienced rescue team, that rushes in during or following an incident in an attempt to rescue someone who is down. In the heat of the moment, they take risks that put them in more danger.
