Read the first 7 Workplace Ergonomic flashcards as text

  1. Which environmental factor is most directly linked to increased musculoskeletal fatigue during cold environments?

    Answer: Vasoconstriction reducing blood flow to muscles and tendons

    Cold temperatures cause vasoconstriction, reducing blood flow and oxygen delivery to muscles and tendons, accelerating fatigue and increasing injury risk.

  2. A call center manager wants to reduce neck strain among headset users. What is the FIRST ergonomic action to recommend?

    Answer: Ensure the monitor top is at or slightly below eye level

    Positioning the monitor so the top is at or slightly below eye level keeps the neck in a neutral posture, reducing cervical muscle loading.

  3. When performing a REBA assessment, a score of 11 or higher indicates what level of action?

    Answer: Very high risk — implement changes immediately

    A REBA score of 11–15 indicates very high musculoskeletal risk, requiring immediate corrective action.

  4. Which standard provides OSHA's general framework for ergonomics in general industry, though it is not a standalone OSHA standard?

    Answer: General Duty Clause (Section 5(a)(1) of the OSH Act)

    OSHA enforces ergonomics in general industry under the General Duty Clause, which requires employers to provide a workplace free from recognized hazards.

  5. For a precision assembly task requiring fine motor work, at what height relative to elbow level should the work surface be set?

    Answer: At elbow level or slightly above

    Fine or precision work benefits from a surface at or slightly above elbow height to allow visual proximity and reduce shoulder shrug.

  6. Which pinch grip type generates the highest contact stress on tendons and is most associated with de Quervain's tenosynovitis?

    Answer: Lateral (key) pinch

    Lateral (key) pinch involves forceful thumb abduction/extension, stressing the abductor pollicis longus and extensor pollicis brevis tendons involved in de Quervain's.

  7. An ergonomist measures whole-body vibration during forklift operation. Which ISO standard guides acceptable daily vibration exposure limits?

    Answer: ISO 2631-1

    ISO 2631-1 specifies methods for measuring whole-body vibration and provides health, comfort, and perception guidance values.
