In which example is injury prevention through ergonomics clear?

Answer and explanation

Correct answer: Bending the knees and keeping the back straight while lifting heavy objects

Answer: A, because bending the knees and keeping the back in a neutral, straight position helps the worker use the leg muscles and reduces excessive bending and strain on the back. A safe lifting action also involves keeping the load close to the body, lifting smoothly, and avoiding sudden jerks. Option B is wrong because a jerk can create sudden force and increase the chance of muscle or back injury. C is wrong because darkness reduces visibility and increases the risk of collision or dropping the load. D is wrong because repeatedly maintaining a poor posture can create fatigue and strain. The example in A demonstrates body mechanics designed to reduce risk. Memory cue: stable posture, bent knees, close load, smooth movement.
