If I have multiple entrants into the same confined space at the same time, do I have to have multiple retrieval lines/systems?  We have installed a concrete pit that qualifies as a permit required confined space and I am new to the confined space regs.

Thanks for any and all help!

Todd,

Good question. I never considered it before. check out 1910.146(k)(3). Paragraph (iii) seems to indicate that you could have each of entrants attached to a fixed point and attach the correct line retrieval system as needed. Just my opinion.

1910.146(k)(3)

To facilitate non-entry rescue, retrieval systems or methods shall be used whenever an authorized entrant enters a permit space, unless the retrieval equipment would increase the overall risk of entry or would not contribute to the rescue of the entrant. Retrieval systems shall meet the following requirements.

1910.146(k)(3)(i)

Each authorized entrant shall use a chest or full body harness, with a retrieval line attached 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 may be used in lieu of the chest or full body harness if the employer can demonstrate that the use of a chest or full body harness is infeasible or creates a greater hazard and that the use of wristlets is the safest and most effective alternative.

1910.146(k)(3)(ii)

The other end of the retrieval line shall be attached to a mechanical device or fixed point outside the permit space in such a manner that rescue can begin as soon as the rescuer becomes aware that rescue is necessary. A mechanical device shall be available to retrieve personnel from vertical type permit spaces more than 5 feet (1.52 m) deep

I called the OSHA Compliance Guidance Group about a similar situation.

In summary, each man needs his own retrieval line and they can be hooked to the same retrieval system.

Another note:  the retrieval system must be able to support the total weight of all the workers.
