Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Scope. These Orders apply to the design,
						construction, testing, use and maintenance of personnel platforms, and the
						hoisting of personnel platforms on load lines of cranes and derricks.
(b) Definitions. For the purpose of section
						5004 of these Orders the following
						definitions apply:
Failure. Failure means load refusal, breakage, or
						  separation of components. Hoist (Hoisting). Hoist means all crane or derrick
						  functions such as lowering, lifting, swinging, booming in and out or up and
						  down, or suspending a personnel platform.
Load Refusal. Load refusal means the point where the
						  ultimate strength is exceeded.
(c) General Requirements. The use of a crane
						or derrick to hoist employees on a personnel platform is prohibited, except
						when the erection, use, and dismantling of conventional means of reaching the
						worksite, such as a personnel hoist, ladder, stairway, aerial lift, elevating
						work platform or scaffold, would be more hazardous or is not possible because
						of structural design or worksite conditions.
(d) Operational Criteria.
(1) Hoisting of the personnel platform shall
						be performed in a slow, controlled, cautious manner with no sudden movements of
						the crane or derrick, or the platform.
(2) Load lines shall be capable of
						supporting, without failure, at least seven times the maximum intended load,
						except that where rotation resistant rope is used, the lines shall be capable
						of supporting without failure, at least ten times the maximum intended load.
						The required design factor is achieved by taking the current safety factor of
						3.5 [required under section
						4884(b) of these
						Orders] and applying the 50 percent derating of the crane capacity which is
						required by section
						5004(d)(5) of
						these Orders.
(3) Load and boom
						hoist drum brakes, swing brakes, and operator actuated secondary braking and
						locking devices such as pawls or dogs or automatic secondary brakes shall be
						engaged when the occupied personnel platform is in a stationary working
						position.
(4) The crane shall be
						uniformly level in accordance with the manufacturer's specifications, not to
						exceed one percent of level grade, and located on footing that a qualified
						person has determined to be firm and stable. Cranes equipped with outriggers or
						stabilizers shall have them all fully deployed following manufacturer's
						specifications, insofar as applicable, when hoisting employees.
(5) Capacity:
(A) Use of suspended personnel platforms. The
						total weight of the loaded personnel platform and related rigging shall not
						exceed 50 percent of the rated capacity for the radius and configuration of the
						crane or derrick, except during proof testing.
(B) Use of boom-attached personnel platforms,
						when approved by the crane manufacturer or certified agent. The total weight of
						the loaded personnel platform shall not exceed 50 percent of the rated capacity
						for the radius and configuration of the equipment, except during proof
						testing.
(C) Hoisting personnel
						without a personnel platform. When hoisting personnel without a personnel
						platform pursuant to exceptions to subsection (k)(10), the total load shall not
						exceed 50 percent of the rated capacity for the radius and configuration of the
						equipment, except during proof testing.
(6) The use of machines having live booms
						(booms in which lowering is controlled by a brake without aid from other
						devices which slow the lowering speeds) is prohibited.
(7) Only wire rope or steel chain slings and
						pendants shall be used for suspending personnel platforms.
(8) Proper operation required. Personnel
						hoisting operations shall not begin unless the devices listed in this section
						are in proper working order. If a device stops working properly during such
						operations, the operator shall safely stop operations. Personnel hoisting
						operations shall not resume until the device is again working properly.
						Alternative measures are not permitted. (See Section
						3314 for tag-out and related
						requirements.)
