A computer workstation assessment reveals a user's monitor is positioned 18 inches away with the top of the screen at eye level. What adjustment is most appropriate?
Answer: Lower the monitor so the top is 2–3 inches below eye level
The top of the monitor should be at or slightly below eye level to prevent neck extension.
When conducting a manual materials handling (MMH) assessment using the NIOSH Lifting Equation, a Recommended Weight Limit (RWL) of 15 lbs is calculated but the actual lift is 30 lbs. What does a Lifting Index (LI) of 2.0 indicate?
Answer: The task poses a significant risk and redesign is warranted
An LI greater than 1.0 indicates increased risk of low back injury, and an LI of 2.0 signals significant musculoskeletal risk requiring engineering controls.
An ergonomist is evaluating a repetitive assembly task where workers flex their wrists more than 45 degrees repeatedly. Which intervention is the MOST direct engineering control?
Answer: Redesign the tool handle to maintain a neutral wrist posture
Redesigning the tool to keep the wrist neutral is an engineering control that eliminates the hazard at the source.
A job demands analysis for a firefighter role must include physical demands that are:
Answer: Derived from critical tasks essential to the job regardless of frequency
Physical demands in a job demands analysis must reflect the critical, essential functions of the role, not just frequent tasks.
During a participatory ergonomics intervention, workers consistently identify awkward reaching as the main problem but management prioritizes pace. What is the ergonomist's best course of action?
Answer: Advocate for worker-identified hazards using objective risk assessment data
Ergonomists should use objective data to substantiate worker-identified hazards and align solutions with both safety and organizational goals.
A standing workstation is introduced to reduce sedentary time. After two weeks, workers report lower-back and leg fatigue. What is the FIRST corrective step?
Answer: Provide anti-fatigue mats and footrests and encourage posture variation
Anti-fatigue mats, footrests, and posture variation are front-line engineering and administrative controls for standing fatigue.
When applying the Strain Index (SI) to evaluate an upper-extremity task, which factor is NOT one of the six task variables assessed?
Answer: Ambient temperature of the workstation
The Strain Index uses intensity, duration, efforts per minute, hand/wrist posture, speed of work, and duration per day — ambient temperature is not included.
