Storing materials at which height makes lifting easier and safer?

• A. Shoulder height
• B. Waist height
• C. Above head height
• D. On the floor

Answer: (B)

Storing at waist height keeps the load close to your body and lets you lift with your legs while keeping the spine in a neutral position. This reduces the lever arm of the weight, which lowers the strain on your lower back and shoulders and makes the lift safer and easier.

Reaching to higher levels requires more shoulder and arm effort and overhead work, increasing fatigue and the risk of dropping or losing control of the load. Lifting from the floor forces you to bend and round the back, putting extra stress on the lumbar region. Storing at shoulder height is better than above head height but still involves more arm reach and less control than keeping the load near the waist. So waist height is the most ergonomically favorable option for lifting, promoting safer posture and easier handling. If possible, use carts or mechanical aids to keep items at or near waist height.
