Which item below is a known factor that can contribute to back injury in the workplace?

• A. Lifting with the back bowed out
• B. Sitting with proper posture
• C. Regular stretching
• D. Using ergonomic equipment

Answer: (A)

Poor lifting mechanics threaten the back because the spine should stay in a neutral position when lifting. Lifting with the back bowed out places the load on the lumbar spine, increasing moments that stress muscles, ligaments, and discs. This can cause strains, spasms, or disc injuries, especially with heavy or awkward loads. The safer approach uses the legs: bend at the hips and knees, keep the load close to the body, maintain a straight back, and avoid twisting or jerking. Protective practices like sitting with proper posture, regular stretching, and using ergonomic equipment help support the spine and reduce stress during daily tasks. So, lifting with the back bowed out is the known factor that contributes to back injury, while the other options reflect safer practices.
