Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
					 Hoisting machines shall be designed, installed, and maintained to vertically
					 raise and lower the rated load plus the weight of equipment and
					 ropes.
(b) The hoisting machine
					 shall be equipped with brakes capable of stopping and holding 125 percent of
					 rated hoisting capacity under all operating conditions.
(c) The hoisting machine shall be secured in
					 position so as to prevent lateral movement, shifting, or
					 dislodgement.
(d) The location and
					 arrangement of the hoisting machine, tower, and related sheaves shall be such
					 that proper wrapping of the wire rope on the drum will be assured to prevent
					 "overriding," fouling, improper spacing, or any other condition which will
					 cause damage to the wire rope or hoisting machine.
(e) Hoisting machines shall not be left
					 unattended with the load suspended.
(f) Adequate blocking and bracing shall be
					 provided between the hoisting machine and the tower to prevent the transmission
					 of any unbalanced lateral forces to the tower resulting from the pull of the
					 hoisting ropes.
(g) When hoisting
					 machinery is set on an elevated platform, such platforms shall be of
					 substantial construction, properly engineered, and provided with guardrails and
					 toeboards which conform to these Orders.
(h) Wire hoisting ropes within 7 feet of
					 floor or ground shall be guarded by an enclosure or fence.
(i) All gears on hoisting machines shall be
					 completely guarded.
(j) Not more
					 than one platform winch head, boom, or bucket shall be operated at the same
					 time by any one hoisting machine.
(k) Brake drums shall be kept free of oil,
					 grease, or any other substance which reduces their efficiency.
(l) Mechanical brakes shall be so installed
					 as to stop movement of the winding drum, and equipped with a positive acting
					 latch or other mechanical device, designed as part of the hoist, which will
					 hold the brake in the engaged position.
(m) Each manually operated hoisting machine
					 shall be equipped with an effective pawl and ratchet capable of holding the
					 rated load capacity when it is suspended.
(n) Internal-combustion-engine exhaust pipes
					 shall be arranged to exhaust away from workmen so the gases will be dissipated
					 harmlessly. A muffler shall be installed to reduce the noise.
(o) Only approved safety cans shall be used
					 for fueling internal-combustion engines. When gravity-type fuel systems are
					 used, a cutoff valve shall be installed between the internal-combustion engine
					 and the fuel-supply tank.
(p) Open
					 light, flames, or spark-producing devices shall be kept at a safe distance
					 while refueling internal-combustion engines, and no person shall smoke or carry
					 lighted smoking materials in the immediate area. The engine shall be stopped
					 during refueling.
(q) A fire
					 extinguisher which meets the requirements of the General Industry Safety Orders
					 shall be part of the hoisting equipment.
(r) The operation of every hoist shall be
					 controlled by an electrically or mechanically designed signal system. Manual
					 signals may only be used when visibility and distance permit, and the signals
					 can be relayed directly to the hoist operator. See Section
					 1605.21 for recommended signal
					 systems.
(s) The platform, cage, or
					 bucket shall be brought to its lowest position, the hoisting machine shall be
					 shutdown and positively secured against accidental start-up when men climb the
					 hoist tower or work on any part of the tower below the cathead. The platform,
					 cage, or bucket may be used to raise workmen for authorized maintenance and
					 repairs that cannot be done otherwise.
(t) All hoisting equipment, including brakes,
					 gears, levers, and wire rope, shall be visually inspected daily. All broken,
					 worn, or defective parts shall be repaired or replaced when
					 discovered.
(u) Electrical
					 equipment shall be effectively grounded. Ground cables shall be enclosed or
					 shielded as necessary, and shall be tagged for identification.
(v) Each automatically operated
					 electrical-motor-driven hoist shall be provided with a mechanical automatic
					 motor brake, or equivalent device, to hold the load automatically in case of
					 power failure.
