REMOVAL:
Death or serious injury could occur if unauthorized or unnecessary personnel are
in the hoisting area. Permit only personnel actually engaged in the hoisting
operation to be near the unit and hoisting equipment. All instructions for the
hoist- ing operations must come from one authorized person.
Injury to personnel or damage to equipment could occur from improper hoisting.
Hoist the load slowly to avoid tearing out lifting bail assembly, slipping slings, or
load shift. Do not jerk the load or swing it from side-to-side when hoisting. This
places additional stress on hoisting components which can cause failure and loss
of load. Be sure hoisting equipment is on solid footing and is suitable for the size
of the load. Watch boom angle and overhead clearance when hoisting.
