Which of the following is NOT an ergonomic physical risk factor?

• A. Slip hazards on wet floors.
• B. Awkward positions.
• C. Repetitive motions.
• D. Contact Stresses.

Answer: (A)

Ergonomic physical risk factors are about how the body is used during work and how that use can lead to musculoskeletal problems. Awkward positions challenge joints and muscles by forcing them out of a comfortable alignment, increasing strain. Repetitive motions keep stressing the same tendons and muscles, which can lead to cumulative injuries like tendonitis or carpal tunnel. Contact stresses come from pressure or friction on the skin from sharp edges or hard surfaces, which over time can harm nerves and soft tissue. Slip hazards on wet floors, while very important for overall safety, relate to the risk of slipping and falling rather than how the body is mechanically used during tasks. So the item that is not an ergonomic physical risk factor is slip hazards on wet floors.
