Which worker is at the highest risk for injury during a factory walk-through?

The worker wearing a back brace and bending at the waist when lifting is at the highest risk for injury during a factory walk-through due to the mechanics of lifting and the limitations of protection provided by a back brace. While a back brace can offer some support, it does not eliminate the risk of injury, especially when bending at the waist to lift heavy objects. This positioning can place undue stress on the lower back and increase the likelihood of strains or sprains.

Proper lifting techniques typically involve using the legs for strength rather than bending at the waist, which is a risk factor for back injuries. Additionally, wearing a back brace may create a false sense of security, leading individuals to lift heavier objects than they should or to use improper body mechanics. Therefore, this scenario embodies a high-risk behavior for injury in a factory environment, making it a correct choice for identifying the worker at the greatest risk.
