shall be available while anyone is underground to provide the mechanical
escape facilities, if required, to the bottom of each shaft and slope
opening that is part of an escapeway within 30 minutes after personnel on

However, no operator is required for automatically operated cages,
platforms, or elevators.
(e) Mechanical escape facilities shall have rated capacities consistent
with the loads handled.
(f) Manually-operated mechanical escape facilities shall be equipped with
indicators that accurately and reliably show the position of the

that the examination was made. Certifications shall be made at or near the
facility examined.
