Summary- Operating Procedure

1. Everyone in the immediate vicinity is clear of the load and aware that the load is being moved.

10. When traveling with load, accelerate and brake gently.

 

11. Travel with load as close to ground as possible and keep speed to a minimum.

 

12. Have unobstructed view of load, chaser and work area.

 

13. Work only at areas that are well illuminated.

 

14. When walking with a load, walk behind and beside the load. Guide load with palm of the hand and do not hold the slings.

 

15. Suspended load must not be left untended.
