A technician must move a heavy server chassis from the floor onto a rack shelf. Which of the following actions BEST reduces the risk of personal injury during the lift?
- ABend at the knees, keep the back straight, and lift using the legs
- BBend at the waist and lift quickly to minimize strain time
- CTwist at the waist while carrying the chassis to the rack
- DHold your breath throughout the lift to stabilize the core
Show answer & explanationAnswer & explanation
Correct answer: A. Bend at the knees, keep the back straight, and lift using the legs
Proper lifting technique requires bending at the knees, keeping the back straight, and using leg muscles to lift, which minimizes strain on the spine. Bending at the waist, holding breath, or twisting while carrying all increase the risk of back injury.
Why the other options are wrong
- B. Bending at the waist places excessive strain on the lower back.
- C. Twisting while carrying a load greatly increases back injury risk.
- D. Holding breath does not prevent injury and can cause other issues.
Proper Lifting Technique
A safety practice of bending at the knees and lifting with the legs, keeping the back straight, to prevent workplace injury when moving heavy equipment.
- Keep back straight, bend knees
- Use leg muscles, not back muscles
- Avoid twisting while carrying a load
Memory trick: Lift with your legs, not your back.
