What is the correct method to lift heavy loads to prevent musculoskeletal injuries?

• A. Use proper lifting technique, get help or use mechanical aids, and keep the load close to the body with a straight back.
• B. Lift with your back twisted and keep the load away from your body.
• C. Use only one hand to lift.
• D. Ignore safety procedures and hurry.

Answer: (A)

Preventing musculoskeletal injuries when lifting heavy loads hinges on three core ideas: use proper lifting technique, get help or use mechanical aids when the load is too heavy, and keep the load close to the body with a straight back. Each part plays a role in protecting the spine and distributing effort safely.

Using proper lifting technique means bending at the hips and knees and keeping the spine in a neutral, straight position as you lift. This shifts the load from the back to the stronger leg muscles, reducing strain on the spine. Keeping the load close to the body minimizes the lever arm—the distance the weight pulls on your torso—so there’s less torque on your back. If the load is too heavy to handle alone, don’t push through; ask for help or bring in a mechanical aid. That way the work is shared or supported, further reducing injury risk.

Twisting the back, lifting with the back, or keeping the weight away from the body increases spinal stress and makes injury more likely. Lifting with one hand or rushing through the lift also raises the chance of losing control, dropping the load, or slipping, which can cause acute injuries. Ignoring safety procedures eliminates the built-in protections that help keep you safe.
