When lifting a heavy object from a low shelf, which technique is safest?

Question

Accepted Answer

Squat down with legs apart, keep the object close to your body, and lift with your legs. Squatting with legs apart, keeping the object close to your body, and lifting with your legs protects your back by using the strongest muscles. Bending at the waist (A) strains the lower back. Reaching far and pulling quickly (C) causes loss of balance and back strain. Twisting the spine while lifting (D) is a leading cause of back injuries. Proper body mechanics are essential for CNAs who perform frequent lifting and transfers.
