CIEE Ergonomic Principles & Evaluation Techniques 4

Question 1

The Borg CR10 Scale used in ergonomic assessments primarily measures:

Accepted Answer

Perceived intensity of a specific body part's discomfort or pain

Answer

The Borg CR10 Scale is a ratio scale used to quantify perceived intensity of specific sensations, including pain or discomfort in a targeted body region.

Question 2

A manufacturing facility wants to evaluate cumulative low-back disorder risk for a job involving multiple lifting tasks throughout the shift. Which tool is best suited for this analysis?

Accepted Answer

Composite Lifting Index (CLI) from the Revised NIOSH Lifting Equation

Answer

The Composite Lifting Index (CLI) extends the NIOSH equation to account for cumulative exposure across multiple different lifting tasks in a single job.

Question 3

Contact stress (pressure points) is considered an ergonomic risk factor because it:

Accepted Answer

Compresses tendons, nerves, and blood vessels, reducing circulation and increasing injury risk

Answer

Contact stress from hard or sharp workstation edges compresses soft tissue structures, impairing circulation and increasing CTD risk.

Question 4

During an ergonomic evaluation of a keyboard-intensive data entry job, the evaluator notices the monitor is positioned 90 cm from the worker's eyes. This distance is:

Accepted Answer

Too far for most workers; 50–70 cm is the recommended range

Answer

The recommended monitor viewing distance for most office tasks is 50–70 cm (approximately arm's length), with adjustments based on screen size and font.

Question 5

Which of the following is the primary purpose of a 'job demands analysis' (JDA) in an ergonomic program?

Accepted Answer

To systematically document the physical, cognitive, and environmental demands of a job for comparison with worker capabilities

Answer

A JDA systematically documents all task demands—physical, cognitive, and environmental—to enable matching of job requirements with worker abilities and to identify hazard control opportunities.
