  1. Which observational tool uses a body-part coding system to record awkward postures during a task cycle?

    Answer: OWAS (Ovako Working Posture Analysis System)

    OWAS categorizes trunk, arm, and leg postures into coded combinations to quantify postural exposure during work.

  2. A task analysis reveals a worker lifts a 40-lb box from floor to shoulder height 80 times per shift. Which variable of the Revised NIOSH Lifting Equation would be MOST penalized?

    Answer: Frequency Multiplier (FM)

    High repetition rates reduce the Frequency Multiplier, which directly lowers the Recommended Weight Limit (RWL).

  3. In cognitive task analysis, which technique involves asking experts to 'think aloud' while performing a task to capture decision-making processes?

    Answer: Protocol analysis (verbal protocol)

    Protocol analysis captures concurrent verbalization during task performance to reveal cognitive steps and decision points.

  4. An ergonomist measures wrist deviation using a electrogoniometer during assembly work. This is an example of which level of exposure assessment?

    Answer: Direct measurement

    Electrogoniometers directly quantify joint angle over time, representing the highest level of objective physical exposure measurement.

  5. The REBA (Rapid Entire Body Assessment) tool assigns higher action levels (3-4) based on what outcome?

    Answer: Increasing musculoskeletal risk requiring immediate intervention

    REBA action levels 3-4 indicate high to very high risk, triggering urgent ergonomic intervention recommendations.

  6. A job demands analysis identifies that a task requires sustained pinch grip for 45 minutes continuously. Which ergonomic risk factor does this primarily represent?

    Answer: Static loading

    Sustained pinch grip without rest is a form of static muscular loading that impairs blood flow and causes fatigue.

  7. When using the Strain Index to evaluate a hand-intensive task, which multiplier accounts for the duration of exertion per cycle?

    Answer: Duration of Exertion Multiplier (DE)

    The Duration of Exertion Multiplier in the Strain Index specifically quantifies the proportion of the cycle spent in exertion.
