  1. Which anthropometric measure is most critical when setting seated workstation height for a diverse workforce?

    Answer: Popliteal height

    Popliteal height (back of knee to floor) determines optimal seat height to allow feet to rest flat and thighs to be roughly horizontal.

  2. A warehouse employee frequently lifts boxes from floor level. Which NIOSH lifting equation multiplier is MOST penalizing in this scenario?

    Answer: Vertical Multiplier (VM)

    Lifting from floor level places the origin below knuckle height, significantly reducing the Vertical Multiplier and thus the RWL.

  3. What is the recommended maximum sustained pushing force for an average adult worker on a level surface according to ergonomic guidelines?

    Answer: Under 20 lbs (89 N)

    Ergonomic guidelines generally recommend sustained horizontal push/pull forces not exceed approximately 20 lbs (89 N) to minimize injury risk.

  4. Which type of chair adjustment is most important for preventing pressure on the back of the thighs?

    Answer: Seat pan depth (fore-aft)

    Seat pan depth must leave 2–4 finger widths between the seat edge and the back of the knees to avoid popliteal pressure.

  5. A worker develops lateral epicondylitis ('tennis elbow'). Which workstation condition is the most likely ergonomic contributor?

    Answer: Repetitive forearm pronation/supination with high grip force

    Lateral epicondylitis is associated with repetitive wrist extension and forearm rotation combined with forceful gripping, overloading the common extensor tendon.

  6. In ergonomic hierarchy of controls, which solution is considered more effective than administrative controls?

    Answer: Engineering controls such as lift assists

    Engineering controls physically change the task or environment, providing more reliable hazard reduction than administrative controls that rely on behavior.

  7. Which symptom pattern is most consistent with carpal tunnel syndrome (CTS) in a keyboard worker?

    Answer: Numbness and tingling in the thumb, index, and middle fingers, especially at night

    CTS compresses the median nerve, causing numbness and tingling in the thumb, index, and middle fingers, often worse at night.
