level of personnel competence.
13.14. EMERGENCY RESPONSE
13.14.1. Emergency Response Plan
A plan of action should be written with provisions to conduct a timely rescue for individuals in a
confined space should an emergency arise.
13.14.2. Retrieval Systems or Methods to Facilitate Non-entry Rescue
Retrieval systems should be used whenever an authorized person enters a permit space, unless the
equipment increases the overall risk of entry or the equipment would not contribute to the
rescue of the entrant. Retrieval systems should have a chest or full body harness and a
retrieval line attached at the center of the back near shoulder level or above the head. If
harnesses are not feasible or create a greater hazard, wristlets may be used in lieu of the harness.
The retrieval line should be firmly fastened outside the space so that rescue can begin as soon as
anyone is aware that retrieval is necessary. A mechanical device should be available to retrieve
personnel from vertical confined spaces more than five feet deep.
