• Materials being hoisted must be rigged by a qualified rigger in a way that prevents unintentional displacement and uses hooks with self-closing latches (or their equivalent).

When employees are engaged in hooking, unhooking, or guiding the load, or in the initial connection of a load to a component or structure, and are within the fall zone, all of the following criteria must be met:

• The materials being hoisted must be rigged to prevent unintentional displacement.
• Hooks with self-closing latches or their equivalent must be used.
  • Exception: “J” hooks are permitted to be used for setting wooden trusses. This exception is designed to allow the truss to be unhooked without the need for an employee to go out on the truss. This avoids the additional exposure to fall hazards that would otherwise occur from going out on the truss to release a latched hook.
• The materials must be rigged by a qualified rigger.

When a load is being landed, only employees needed to receive a load are permitted to be within the fall zone. An employee receiving a load will typically need to be within the fall zone when the load is being landed because that is the time when the load needs to be guided to a specific landing point.
