 Safety Rules for Crane Operators 



1. Safety shall always be given first consideration in the operation of cranes. Operators 

 shall constantly bear in mind that the safety of personnel on deck, as well as their own safety, 

 depends upon the careful operation of the crane. Therefore, operators should be permitted to 

 operate cranes only when they are physically fit. Any illness will be reported to the super- 

 visor immediately. 



2. If any doubt exists concerning the safety of any situation or condition, the operator 

 shall not move the crane or proceed with the lift until the unsafe condition is corrected and 

 the supervisor has decided that the situation is safe. 



3. Operators shall familiarize themselves with the crane mechanism and its proper care, 

 and with all operating safety rules. 



4. Both hands shall be used whenever ascending or descending the vertical crane ladder. 



5. Operators shall keep crane cabs clean at all times. 



6. Operators shall examine their crane daily for defective brakes, loose parts, or any 

 condition which could make the crane unsafe. 



7. Whenever adjustments or repairs are necessary, the condition shall be reported to the 

 supervisor immediately. 



8. At the beginning of each shift, operators shall test each limit switch by slowly raising 

 the block until the limit switch opens the circuit. 



9. At least two full wraps of hoist cable shall be kept on the hoist drum. 

 10. When leaving the crane, operators shall: 



a. Spot the crane at approved access. 



b. Raise all hooks to the upper limit switch. 



c. Move all controls to the "off" position. 



d. Lock the crane disconnect switch in the "off" position. 

 Safe Lifting and Transportation of Heavy Loads 



1. The safe transportation by cranes of heavy loads depends upon the following three basic 

 elements: 



a. The capacity and safe operating condition of the mechanical lifting equipment. 



b. The capacity and condition of the hitching devices and accessories used. 



c. The capabilities of the persons that operate, use, inspect, and repair the lifting 



equipment and hitching devices. 



2. The capacity of all hoisting equipment is posted and shall not be exceeded.
