California Code of Regulation- Title 8, Section 5157. Permit -Required r'mfined Spaces. Page 14 of 14 <br />J 1 <br />Y <br />(3) To facilitate non -entry rescue, retrieval systems or methods shall be used whenever an authorized <br />entrant enters a permit space, unless the retrieval equipment would increase the overall risk of entry or <br />would not contribute to the rescue of the entrant. Retrieval systems shall meet the following <br />requirements. <br />(A) Each authorized entrant shall use a chest or full body harness, with a retrieval line attached at a <br />suitable point so that when rescued, the entrant presents the smallest possible profile (for example at <br />the center of the entrant's back near shoulder level, or above the entrant's head). Wristlets may be used <br />in lieu of the chest of full body harness if the employer can demonstrate that the use of a chest or full <br />body harness is infeasible or creates a greater hazard and that the use of wristlets is the safest and most <br />effective alternative. <br />(B) The other end of the retrieval line shall be attached to a mechanical device or fixed point outside <br />the permit space in such a manner that rescue can begin as soon as the rescuer becomes aware that <br />rescue is necessary. A mechanical device shall be available to retrieve personnel from vertical type <br />permit spaces more than 5 feet deep. <br />(4) If an injured entrant is exposed to a substance for which a Material Safety Data Sheet (MSDS) or <br />other similar written information is required to be kept at the worksite, that MSDS or written <br />information shall be made available to the medical facility treating the exposed entrant. <br />(1) Appendices. Appendices A through E serve to provide information and non -mandatory guidelines <br />to assist employers and employees in complying with the appropriate requirements of this section. <br />NOTE: Authority cited: Section 142.3, Labor Code.
