Personal risk factors for ergonomic hazards include ______________.

• A. Body Size, Medical Condition, Physical Condition
• B. Age
• C. Hair Color
• D. Diet

Answer: (A)

The main idea here is that ergonomic risk is influenced by the individual performing the task. Personal risk factors are about how a person’s body and health affect their ability to handle work demands safely. Body size matters because height, limb length, and weight affect reach, posture, and the amount of force required to move or operate controls. Medical conditions—like back problems, joint injuries, or repetitive strain injuries—make certain positions or movements more painful or risky, increasing the chance of getting hurt. Physical condition refers to strength, flexibility, endurance, and overall fitness, which determine how well someone can maintain neutral postures, handle fatigue, and recover from exertion. When you combine these three aspects, you get a clear picture of who is more susceptible to ergonomic hazards in a given task.

Age, hair color, or diet don’t directly determine immediate ergonomic risk in most typical workplace tasks. Age can influence risk, but it’s the physical size and health status that more directly affect how well a person can safely perform a task. Hair color has no bearing on ergonomic safety, and while diet affects overall health, it doesn’t define the immediate ergonomic hazard to a specific job.
