Note: | For additional requirements relating to inspections see WA C 296-155-53405. |
Note: | The dimension of the hook cannot be reduced more than 10% of its original value, unless otherwise recommended by the manufacturer. |
Note: | For requirements relating to wedge sockets, see WAC 296-155-56115(2). |
Exception: | When you can demonstrate that it is neither feasible to erect such barriers on the ground nor on the crane, the hazard areas must be clearly marked by a combination of warning signs (such as Danger-Swing/Crush Zone) and high visibility markings on the crane that identify the hazard areas. In addition, you must train each employee to understand what these markings signify. |
Note: | An employee is essential to the operation if the employee is conducting one of the following operations and you can demonstrate it is infeasible for the employee to perform that operation from outside the fall zone: * Physically guide the load; * Closely monitor and give instructions regarding the load's movement; or * Either detach it from or initially attach it to another component or structure (such as, but not limited to, making an initial connection or installing bracing). |
Exemption: | The provisions in this section do not apply to working gear (such as slings, spreader bars, ladders, and welding machines) where the weight of the working gear is negligible relative to the lifting capacity of the equipment as positioned, and the working gear is suspended over an area other than an entrance or exit. |
Note: | For additional requirements relating to leaving the crane unattended for tower, self-erecting, overhead/bridge and derricks see: * WAC 296-155-53915, Tower cranes-Operations; * WAC 296-155-54115, Self-erecting tower cranes-Operations; * WAC 296-155-54215, Overhead/bridge cranes and gantry cranes-Operations; * WAC 296-155-54320, Derricks-Operations. |
Note: | The provisions in subsections (58) and (59) of this section do not apply to modifications made or approved by the U.S. military. |
* The suspended load can be expected to remain still when in a static (nonmoving) condition or does not swing or rotate in a hazardous manner;
* The movement of the crane or boom cannot be expected to cause the load to swing or rotate in an uncontrolled manner that may create a hazard;
* The operator is in control of the movement of the load and a hazardous condition is not created.
Note: | For additional lockout/tagout procedures for electrical circuits, see WAC 296-155-429. |
