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 11/15/2018

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 P.89 11/15/2018

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 11/15/2018
