Retrieval Systems
Retrieval systems for non-entry rescue operations must meet the following requirements:
- Only equipment suitable for retrieval will be used. Examples of unsuitable equipment include:
- retrieval lines have a reasonable probability of becoming entangled with the retrieval lines used by other authorized entrants, or
- retrieval lines will not work due to the internal configuration of the permit space.
Only equipment suitable for retrieval will be used.
- Each authorized entrant must use a chest or full body harness. The retrieval line must be attached in one of the following locations:
- at the center of the entrant's back near shoulder level,
- above the entrant's head, or
- at another point, which the employer can establish presents a profile small enough for the successful removal of the entrant.
- Wristlets or anklets may be used instead of the chest or full body harness if the employer can prove the use of a chest or full body harness:
- is infeasible, or
- creates a greater hazard and using wristlets or anklets is the safest and most effective alternative.
- The other end of the retrieval line must be attached to a mechanical device or fixed point outside the permit space in such a manner rescue can begin as soon as the rescuer becomes aware rescue is necessary.
- A mechanical device must be available to retrieve personnel from vertical type permit-required confined spaces more than 5 feet (1.52 meters) deep.
- If an injured entrant is exposed to a substance for which a Safety Data Sheet (SDS) or other similar written information is required to be kept at the worksite, that SDS or written information must be made available to the medical facility treating the exposed entrant.
