Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) General Requirements.
(1) When a shaft is used as a means of
					 egress, the employer shall make advance arrangements for power-assisted
					 hoisting capability to be readily available in an emergency, unless the regular
					 hoisting means can continue to function in the event of an electrical power
					 failure at the jobsite. Such hoisting means shall be designed so that the load
					 hoist drum is powered in both directions of rotation and so that the brake is
					 automatically applied upon power release or failure.
(2) Material hoists shall conform to
					 applicable sections of this article and the requirements of Section
					 1605.14 of the Construction Safety
					 Orders relative to mine-type hoisting machines.
(3) There shall be two safe means of access
					 in shafts at all times. This may include a ladder and acceptable hoisting
					 system.
(4) Where any shaft
					 conveyance may swing, bump, or snag against the shaft sides or other structural
					 protrusions, the conveyance shall be guided by fenders, rails, ropes, or
					 equivalent means.
(5) Cranes used
					 for hoisting shall comply with the applicable sections of this article and the
					 requirements of Group 13 of the General Industry Safety Orders; and shall be
					 proof load tested in accordance with Section
					 5021 prior to being placed into
					 service and at least annually thereafter.
(6) Cranes shall be of such design that the
					 load is powered up and down, and so arranged that the load stops or creeps
					 slowly if the motor stops. A system shall be used to prevent the drum from
					 being accidentally disengaged from the mechanical drive (freewheeling) while in
					 use at a shaft.
(7) Crane and hoist
					 drum control levers shall be of a type that return automatically to the "stop"
					 position when the operator's hand is removed.
NOTE: Cranes may have a drum throttle control that
						automatically stops or slows the engine to idling speed when the throttle is
						released.
(8) All cranes
					 used for hoisting shall be provided with a limit switch to prevent a two-block
					 condition.
(9) Limit switches are
					 to be used only to limit travel of loads when operational controls malfunction,
					 and shall not be used as a substitute for other operational controls.
(10) The maximum rate of speed at which
					 material and personnel can be hoisted shall be determined by a qualified
					 person, posted at the hoist controls and shall not be exceeded.
(A) When a hoist is used for both personnel
					 hoisting and material hoisting, load and speed ratings for personnel and for
					 material shall be assigned to the equipment.
(11) A non-combustible hoist house shall be
					 constructed and wherever possible, provide a clear and unobstructed view of the
					 shaft collar. Physical protection shall be provided for the hoistman, hoist
					 drum(s), braking system and drive motors.
(A)
					 A fire extinguisher that is rated at least 2A:10B:C (multi-purpose, dry
					 chemical) shall be mounted in each hoist house.
(12) Whenever glazing is used in a hoist
					 house, it shall be safety glass, or its equivalent, and be free of distortions
					 and obstruction.
(13) All hoists
					 shall be equipped with landing level indicators at the operator's station.
					 Marking of the hoist rope and belt-driven indicators shall not satisfy this
					 requirement.
(14) Hoisting ropes
					 used on cranes shall be accurately marked or equivalent steps taken to indicate
					 when the load has reached certain important positions including top and bottom
					 landings.
(15) Hoist controls shall
					 be clearly labeled and arranged so that the operator can perform all operating
					 cycle functions and reach the emergency cutoff without having to reach beyond
					 the operator's normal operating position.
(16) The Hoists shall be designed so that the
					 load hoist drum is powered in both directions of rotation and so that brakes
					 are automatically applied upon power release or failure. There shall be no
					 friction gearing or clutch mechanism by which the motor or other power source
					 can be disconnected from the hoisting drum.
(17) Makeshift hoisting operations shall not
					 be permitted for personnel or materials.
(18) Construction elevator-type hoists as
					 defined in the Construction Safety Orders shall comply with the California Code
					 of Regulations, Title 8, Article 14 of the Construction Safety
					 Orders.
