WAC 296-307-65016. Use nonentry rescue systems or methods whenever possible

(1) The employer 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) The employer 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) The employer must attach the retrieval line to a mechanical device or fixed point outside the space, so rescue can begin as soon as necessary. (4) The employer must make sure a mechanical device is available to retrieve entrants from vertical spaces more than five feet (1.52 m) deep. Note: When the employer can demonstrate that the use of a chest or full-body harness is not feasible or creates a greater hazard, then the employer may use wristlets or another method shown to be the safest and most effective alternative.
