10. Principles and Practices
General Practices
Properly Trained
Rigger familiar with equipment
Rigger makes final say on safety
If signaling requires only 1 person in charge
Everyone as say to stop
Before moving determine where it is going
Load is free to move, not fastened to ground
Be sure everyone is clear of area
No shock loading
No riding
Do not move over where people are working
Never Leave suspended
Never work under load unless provisions to support are in place
Keep hands fingers out of the way

11. Principles and Practices
Sling Operating Practices
Avoid sharp sling angles
Do not pull sling from under a load when load is resting on sling
Do not leave slings on the ground
Slings should be stored properly
Repair or remove damaged slings
Do not hammer metal mesh slings

12. Principles and Practices
Turning a Load
Most difficult maneuver
Consider all options before moving
Determine center of gravity
Will blocks be required to support load
Can use
One-hook turn
Single-Sling Turn
Two-Hook turn

13. Principles and Practices
Eye Bolts
Have pull ratings and must be remembered p.92
Rigging thought Process
What is done with load
What tools are needed
Is capacity enough and adequate
How can the hook up be
What will happen with path of travel
What will happen once load is lifted
How will load be stored
