when parts weigh over 50 pounds (23 kg) for a single person lift, over 100 pounds

(45 kg) for a two person lift, and over 150 pounds (68 kg) for a three or more person

lift. Do not try to handle heavy parts without lifting equipment. Keep clear of heavy parts

supported only by lifting equipment. Failure to observe this precaution could cause

serious injury or death of personnel.
