Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Inexperienced or untrained employees
					 shall not be permitted to operate the hoist (See Section
					 8499).
(b) Unauthorized persons shall not be allowed
					 in the hoist room.
(c) There shall
					 be no conversation involving the hoisting engineer while the hoist is in
					 motion, or while he/she is attending to signals, except to receive orders or
					 instructions.
(d) A shaft
					 conveyance shall not be left at the collar of the shaft, or at a landing, but
					 must be hung at least 10 feet from the collar of the shaft, or landing when not
					 in use and before the hoist operator leaves his/her post.
(e) Whenever employees are working in a place
					 to which they have been lowered by mechanical power, arrangements must be such
					 that a hoisting engineer or a substitute will be within sight and sound of the
					 signal system at the operator's station.
(f) The hoist shall not be operated and the
					 cage, skip or bucket moved while oiling operations are under way unless
					 clearance is obtained from the oiler. The hoisting engineer shall be notified
					 when oiling operations are to commence and when they are finished.
(g) When employees are working in a shaft
					 without a bulkhead over their heads, the skip, cage or bucket shall not be
					 moved until the employees in the shaft are in the clear. Movement shall not be
					 attempted without permission from those who issued the hold order.
(h) The hoist shall be operated with extreme
					 caution whenever persons are being hoisted up or down.
(i) When a bucket is used for hoisting
					 materials, buckets shall be trimmed prior to hoisting and means shall be
					 provided that will prevent material from falling into the shaft or incline
					 while the bucket is being dumped.
(j) Before any work is commenced in a shaft
					 or incline served by a hoisting system, the hoisting engineer and other
					 employees in the area shall be informed concerning the details and given
					 appropriate instructions. A sign warning that work is being done in the shaft
					 shall be installed at the shaft collar, the operator's station, and at each
					 underground landing.
(k) When
					 employees enter the sump of a shaft or incline a positive stop shall be
					 provided to prevent a load from being lowered on top of them and the hoist
					 engineer shall be notified that the load is not to be moved until the employees
					 working in the sump give the hoisting engineer clearance.
(l) In shafts and inclines precautions shall
					 be taken to prevent materials being hoisted from catching on rocks, timbers or
					 other obstructions.
(m) All
					 timbers, tools, etc., longer than the depth of the bucket, skip cage or other
					 conveyance in which they are to be hoisted or lowered must be lashed at their
					 upper ends to the cable or otherwise secured.
(n) Personnel shall not be permitted to ride
					 on the tops of any shaft conveyance except when necessary to perform
					 inspection, maintenance, or repair of the shaft or hoisting system, in which
					 case they shall be protected by guardrails or approved fall protection
					 systems.
(o) Personnel shall not be
					 permitted to ride on any trip in which the conveyance is loaded with
					 explosives, except in case of a person in charge of explosives and the cage
					 operator. No other hoisting and other activity shall be permitted when
					 transporting explosives.
(p)
					 Personnel and materials or equipment, other than small tools and supplies
					 secured in a manner that will not create a hazard to employees, shall not be
					 hoisted together in the same conveyance. However, if the cage operator is
					 protected from shifting of materials and equipment, then the cage operator may
					 ride with material or equipment in cages or skips which are designed to be
					 controlled by an operator within the cage or skip.
(q) During hoisting operations no load or
					 conveyance shall be lowered directly to any place in a shaft or incline steeper
					 than 20 degrees from the horizontal when employees are in the shaft. All such
					 equipment shall be stopped at least 15 feet above them, and remain there until
					 the signal to lower further is received from them.
(r) The door and gates of all shaft
					 conveyances shall be closed and latched before a signal to move the shaft
					 conveyance is given and they shall remain shut until the conveyance has come to
					 a complete stop.
(s) Employees
					 shall not enter or leave any conveyance if it is in motion or after a signal
					 has been given to the hoisting engineer.
(t) General requirements for cranes and
					 hoists.
(1) Materials, tools, and supplies
					 being raised or lowered, whether within a cage or otherwise, shall be secured
					 or stacked in a manner to prevent the load from shifting, snagging or falling
					 into the shaft.
(2) A warning light
					 suitably located to warn employees at the shaft bottom and subsurface shaft
					 entrances shall flash whenever a load is above the shaft bottom or subsurface
					 entrances, or the load is being moved in the shaft. This section does not apply
					 to fully enclosed hoistways.
