Where available, hoisting routes that minimise employees' exposure to hoisted loads must be used, as far as is consistent with public safety. When a suspended load is not being moved by the operator, the fall zone must be empty except workers hooking, unhooking or guiding a load, making the load's first connection to a structure or component, or operating a concrete hopper or bucket. When workers are in the fall zone hooking, unhooking, guiding or making an initial connection, rigging must keep the load from shifting unintentionally, hooks must have self-closing latches or equivalent (J hooks are permitted for setting wooden trusses), and a qualified rigger must rig the materials. When a load is being landed, only employees needed to receive it may be in the fall zone. During tilt-up or tilt-down operations, nobody may be directly under the load, and only employees essential to the operation may be in the fall zone; an employee is essential only if physically guiding the load, closely monitoring and instructing on its movement, or detaching or initially attaching it (for example an initial connection or bracing), and the employer can show the task cannot feasibly be done from outside the fall zone. A note cross-references 1926.1426: boom free fall is barred with anyone in the fall zone and load line free fall is barred with anyone directly under the load.
