Which of the following is a method to control ergonomic hazards?

Engineering controls, such as redesigning tools or workstations, are a fundamental method to control ergonomic hazards because they involve modifying the work environment or the tasks performed to minimize physical strain and reduce the risk of musculoskeletal disorders. This approach addresses the root causes of ergonomic issues by ensuring that the workplace design promotes good posture, reduces awkward movements, and enhances overall efficiency, thereby directly influencing employee safety and comfort.

Unlike simply increasing work hours, which could lead to fatigue and exacerbate ergonomic risks, or merely providing more breaks, which may help momentarily but does not fundamentally solve the underlying hazards, engineering controls create a lasting impact on the work process. Hiring additional staff might distribute the workload but does not necessarily improve the design of tasks or tools to be more ergonomic. Therefore, redesigning tools or workstations is the most effective and proactive way to control ergonomic hazards in a workplace.
