(a) The following materials shall be stored within 300 feet of each
belt drive or at a location where the material can be moved to the belt drive
within 5 minutes, except that when the ventilating current in the belt
haulageway travels in the direction of the normal movement of coal on the
belt, the materials shall be stored within 300 feet of the belt tailpiece or
at a location where the materials can be moved to the belt tailpiece within 5

the adjacent intake entry; and

containing water outlets between such entry and the belt haulageway (if the
main waterline is in an adjacent entry) shall be maintained accessible and
in safe condition for travel and firefighting activities. Each stopping in
such crosscuts or adjacent crosscuts shall have an access door.
(c) Suitable communication lines extending to the surface shall be
provided in the belt haulageway or adjacent entry.
