Some parts are heavy. Be careful when handling them. Lifting equipment is
needed 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.
