821 Cranes and Derricks Safety II

Work Practices

The following practices must be used:

• Hoisting of the personnel platform must be performed in a slow, controlled, cautious manner, with no sudden movements of the equipment or the platform.
• Platform occupants must keep all parts of the body inside the platform during raising, lowering, and horizontal movement, and must 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.

• Before employees exit or enter a hoisted personnel platform that is not landed, the platform must be secured to the structure where the work is to be performed, unless the employer can demonstrate that securing the platform to the structure would create a greater hazard.
• 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.
• Tag lines must be used when necessary to control the platform.
• Where the platform is not equipped with controls, the equipment operator must remain at the equipment controls, on site, and in view of the equipment, at all times while the platform is occupied.
• Where the platform is equipped with controls, all of the following must be met at all times while the platform is occupied:
• The occupant using the controls in the platform must be a qualified person with respect to their use, including the safe limitations of the equipment and hazards associated with its operation.
• The equipment operator must be at a set of equipment controls that include boom and swing functions of the equipment, and must be on site and in view of the equipment.
• The platform operating manual must be in the platform or on the equipment.

• Employees being hoisted must remain in direct communication with the signal person (where used) or the operator.
• Except over water, employees occupying the personnel platform must be provided and use a personal fall arrest system attached to a structural member within the personnel platform. (The fall arrest system must meet the requirements in § 1926.502). When working over or near water, the requirements of § 1926.106 apply.
• No lifts may be made on any other of the equipment's load lines while personnel are being hoisted, except in pile driving operations.
• Hoisting of employees while the equipment (other than derricks) is traveling is prohibited except in certain circumstances. Derricks are prohibited from traveling while personnel are hoisted.
