Which of the following is a primary goal of ergonomic hand tool design?

• A. Increase tool speed
• B. Reduce musculoskeletal injuries
• C. Increase tool weight
• D. Increase noise

Answer: (B)

Ergonomic hand tool design focuses on keeping the body in a natural, comfortable position and reducing the physical stress of use. The main goal is to lower the risk of musculoskeletal injuries by minimizing grip and pinch forces, avoiding awkward wrist and arm postures, and reducing vibration during repeated use. When tools are shaped to fit the hand, balanced in weight, and have comfortable grips, fatigue decreases and the chances of injuries like tendinitis or carpal tunnel rise less, supporting safer, longer-term work. This safety and health emphasis makes reducing musculoskeletal injuries the best answer.

Other factors like speed, weight, or noise can affect performance or comfort, but they do not address the core aim of preventing these injuries as directly.
