AEP Assessment and Evaluation 2

Question 1

Which observational method involves recording the posture of a worker at random intervals throughout the shift?

Accepted Answer

Work sampling

Answer

Work sampling captures posture or activity data at random intervals to estimate the proportion of time spent in various positions.

Question 2

The Strain Index (SI) primarily assesses risk for musculoskeletal disorders of which body region?

Accepted Answer

Distal upper extremity

Answer

The Strain Index was developed specifically to evaluate risk of distal upper extremity disorders such as carpal tunnel syndrome and tendinitis.

Question 3

In a psychophysical assessment, what does the 'maximum acceptable weight' represent?

Accepted Answer

The load a worker can handle for 8 hours without fatigue beyond accepted limits

Answer

Maximum acceptable weight is the load workers select as manageable over a full shift without unacceptable fatigue, based on psychophysical methodology.

Question 4

Which sensor type is most appropriate for measuring grip force applied to a hand tool?

Accepted Answer

Force transducer

Answer

Force transducers (load cells) measure compressive or tensile forces, making them suitable for quantifying grip force on tools.

Question 5

When evaluating a repetitive task, which parameter of the ACGIH TLV for hand activity level (HAL) reflects the duty cycle of exertion?

Accepted Answer

Hand activity level

Answer

The Hand Activity Level (HAL) score in the ACGIH TLV encapsulates the frequency and duty cycle of hand exertions on a 0–10 scale.
