If a worker is tired after work but has no pain, why is ergonomics still important?
Answer and explanation
Correct answer: Fatigue can increase work errors and the risk of future injury
Fatigue can be an early sign of ergonomic risk caused by poor posture, unsuitable tool or work height, repetitive work, or insufficient rest. A fatigued worker may lose concentration, make errors, and face a greater risk of accidents or later musculoskeletal injury. The absence of pain does not prove that the work setup is safe. Exam tip: ergonomics aims to prevent fatigue, errors, and injury, not merely to treat pain.
