During a permit-required confined space entry into a sewer, Cal/OSHA requires an attendant. What is the attendant's primary role?
a.Enter the space alongside the worker to help with tools
b.Leave the site to get parts while the entrant works
c.Remain outside, monitor the entrant, and be ready to summon rescue without entering
d.Perform the atmospheric testing only, then go home
Giải thích
Under Title 8 §5157, the attendant stays outside the space, continuously monitors conditions and the authorized entrant, maintains communication, and orders evacuation if a hazard arises. The attendant must summon rescue services but must not enter to attempt rescue, because untrained would-be rescuers are frequently the ones who die. This constant outside watch is a core confined-space safeguard.
