Use nonentry rescue systems or methods whenever possible.

(1) You must use nonentry retrieval systems or methods to rescue entrants in a permit-required confined space unless this:
(a) Would increase the overall risk of injury to entrants; or
(b) Would not contribute to the rescue of the entrant.
(2) You must make sure each entrant uses a chest or full-body harness, with a retrieval line attached to the harness at one of the following locations:
(a) At the center of the employee's back, near shoulder level.
(b) Above the employee's head.
(c) At another point which presents a profile small enough for the successful removal of the employee.
(3) You must attach the retrieval line to a mechanical device or fixed point outside the space, so rescue can begin as soon as necessary.
(4) You must make sure a mechanical device is available to retrieve entrants from vertical spaces more than five feet (1.52 m) deep.
Note:
When you can demonstrate that the use of a chest or full-body harness is not feasible or creates a greater hazard, then you may use wristlets or another method shown to be the safest and most effective alternative.
