Prevention of material handling injuries continues to be a difficult task because of the variety of conditions under which supplies and materials are lifted, moved, and carried. Proper attention to the way lifting is done and the use of personal protective equipment can reduce the number of accidents.
Besides providing the necessary foot protection, shoes should be comfortable, low-heeled, and have nonslip soles.
