Which approach best supports prioritization of ergonomic improvements when multiple high-risk jobs are identified?
Answer: Rank jobs by combined risk score and number of affected workers
Prioritizing by risk level multiplied by the number of exposed workers maximizes injury prevention impact per intervention effort.
The 'frequency multiplier' in the NIOSH Lifting Equation decreases (becomes more restrictive) when:
Answer: The lift frequency increases and work duration is longer
Higher lift frequencies and longer shift durations both reduce the frequency multiplier, lowering the Recommended Weight Limit.
A 'before-and-after' ergonomic study without a control group is best described as which study design?
Answer: Pre-post (quasi-experimental) design
A pre-post design measures outcomes before and after an intervention in the same group without a parallel control, making it quasi-experimental.
During a workstation evaluation, a worker's elbow is positioned 20 cm above the keyboard home row. The primary ergonomic concern is:
Answer: Elevated shoulder abduction and increased upper trapezius muscle loading
When the elbow is significantly above the work surface, the shoulder must abduct, increasing upper trapezius activation and musculoskeletal risk.
In ergonomic risk assessment, 'exposure duration' typically refers to:
Answer: The cumulative time per shift the worker performs a specific risk-factor activity
Exposure duration in ergonomics quantifies how much of the shift a worker actually performs a risky task, which directly influences dose-response relationships.
Which statistical measure is most useful for summarizing the central tendency of peak lumbar compression force data collected across 30 workers?
Answer: Mean
The mean (arithmetic average) is the most common measure of central tendency for continuous biomechanical data such as lumbar compression force.
The Washington State Ergonomics Rule (WAC 296-62-051) defines a 'caution zone job' primarily based on:
Answer: Specific exposure thresholds for risk factors such as lift weight, repetition, and awkward posture
Washington State's ergonomics rule categorizes jobs as caution zone based on defined numeric thresholds for lifting weight, hand-force, repetition, and posture risk factors.
