(vi) No more than one person must be hoisted at a time. The platform must be hoisted a few inches with the personnel and materials/tools on board and inspected by a competent person to ensure that it is secure and properly balanced. Not stand, sit on, or work from the top or intermediate rail or toeboard, or use any other means/device to raise their working height. If the load rope is slack, the hoisting system must be inspected to ensure that all ropes are properly seated on drums and in sheaves. (4) If the platform is tied to the structure, the operator must not move the platform until the operator receives confirmation that it is freely suspended. This statement must be posted where the hoist operator can see it. 1926.1431(e)(2) The system used to connect the personnel platform to the equipment must allow the platform to remain within 10 degrees of level, regardless of boom angle. When a wire rope bridle is used, each leg must be connected to a master line (D-ring) or shackle with the load evenly distributed. Loads are permitted to be hoisted by such a winch while employees occupy the personnel platform only where the load on the winch line does not exceed 500 pounds and does not exceed the rated capacity of the winch and platform. When hoisting employees solely for transfer to or from a marine worksite, the following requirements must be met: (1) The employee must be in either a personnel platform or a marine-hoisted personnel transfer device. (ii) Shackles used in place of hooks must be of the alloy anchor type, with either: (A) A bolt, nut and retaining pin, in place; or. The bridles and associated rigging must not have been used for any purpose other than hoisting personnel. Where the terms "personnel platform" or "platform" are used in these paragraphs, substitute them with "boatswains chair.". In addition, the trial lift must be repeated prior to hoisting employees in each of the following circumstances: The equipment is moved and set up in a new location or returned to a previously used location. (ii) The transfer device must be used only for transferring workers. position unless so designed. Hoisting of the personnel platform must be performed in a slow, controlled, cautious manner, with no sudden movements of the equipment or the platform. (8) Access gates/doors. Traveling - equipment other than derricks. The suspension system must be designed to minimize tipping of the platform due to movement of employees occupying the platform 4. Lifting of personnel shall be avoided unless the risk has been demonstrated as being as low as is reasonably practicable. No more than one person must be hoisted at a time. (m) Pre-lift meeting. (ii) Nothing interferes with the equipment or the personnel platform in the course of the trial lift. (2) The system used to connect the personnel platform to the equipment must allow the platform to remain within 10 degrees of level, regardless of boom angle. 16.A.15 Maintenance/repairs of cranes and hoisting equipment. (16) All personnel hoists used by employees shall be constructed of materials and components which meet the specifications for materials, construction, safety devices, assembly, and structural integrity as stated in the American National Standard A10.4-1963, Safety Requirements for Workmen's Hoists. This paragraph does not apply to work covered by subpart R (Steel Erection) of this part and also does not apply to routine personnel access to an underground worksite via shaft as covered by § 1926.800 (Underground Construction) of this part. (C) Equipment travel must be limited to boom length. Platforms used in the transport of personnel must be designed by a qualified person competent in structural design and familiar with national consensus standards governing personnel platform design.

Platforms must not be used to hoist materials or tools when not hoisting personnel. Any condition found during the trial lift and subsequent inspection(s) that fails to meet a requirement of this standard or otherwise creates a safety hazard must be corrected before hoisting personnel.
