During sewer confined-space work, the attendant outside must maintain what capability?
a.Enter to help immediately without equipment
b.Continuous communication with entrants and the ability to summon rescue without entering
c.Leave to get tools as needed
d.Perform the plumbing work
Giải thích
The attendant remains outside, keeps continuous communication with the entrants, monitors conditions, and summons trained rescue if needed, but does not enter the space to attempt rescue alone. Untrained would-be rescuers are a leading cause of confined-space fatalities. Non-entry retrieval systems allow rescue from outside.
