An toànCâu 460 / 521
A permit-required confined space entry requires an attendant who:
a.May enter to help if the entrant collapses inside
b.Can leave the post to take a lunch break
c.Is optional as long as the entrants carry radios
d.Remains outside, monitors the entrants, and never enters to attempt rescue but summons trained rescue services instead
Giải thích
The attendant stays outside, continuously monitors entrants, and calls trained rescuers rather than entering—many confined-space fatalities are would-be rescuers who rushed in. The attendant cannot leave the post or enter, and radios do not eliminate the required attendant for a permit space.
