Which statement about ergonomics is true?

• A. Ergonomics focuses on marketing strategies to increase sales.
• B. Ergonomics designs tasks and tools to fit the worker, reducing injury risk and increasing efficiency.
• C. Ergonomics is primarily about wage negotiations.
• D. Ergonomics is only concerned with lighting in the workspace.

Answer: (B)

Ergonomics means designing tasks and tools to fit the worker, so the body can move safely and efficiently. When workstations, controls, and tools match a person’s size, strength, and reach, the risk of injury from repetitive or awkward movements drops, fatigue decreases, and performance improves. This is why adjustable chairs, monitor height at eye level, grips sized for hands, and appropriately placed work surfaces are classic ergonomic practices. The other options miss the purpose of ergonomics: marketing or wage talks focus on different goals, and limiting ergonomics to lighting ignores how people actually interact with tasks and equipment. So the statement that describes designing tasks and tools to fit the worker to reduce injury risk and increase efficiency is the true one.
