CIEE Workstation Design & Optimization 5

Question 1

During a workstation assessment, an ergonomist observes that a cashier's point-of-sale terminal requires sustained lateral neck rotation of 45°. The most effective long-term solution is to:

Accepted Answer

Reposition the terminal in front of the worker to eliminate neck rotation

Answer

Repositioning the terminal eliminates the source of the awkward posture, making it the preferred engineering control over administrative or PPE measures.

Question 2

Which of the following best describes the purpose of a document holder in a computer workstation setup?

Accepted Answer

Position reference documents at monitor distance and height to minimize head movement and eye refocusing

Answer

A document holder placed adjacent to the monitor reduces repetitive neck rotation and accommodation (refocusing) demands when alternating gaze between paper and screen.

Question 3

In workstation design for a standing assembly line, anti-fatigue mats are most effective at reducing worker discomfort when they provide:

Accepted Answer

Compliant cushioning of 9–19 mm thickness that allows subtle muscle movement

Answer

Anti-fatigue mats work by inducing subtle postural micro-movements through compliant foam, improving venous return and reducing static muscle loading.

Question 4

Which ergonomic principle supports placing controls and displays in order of frequency of use, importance, and functional grouping at a workstation?

Accepted Answer

Principle of importance and frequency of use

Answer

The principle of importance and frequency of use dictates that controls and displays accessed most often or most critically should be in the primary work zone.

Question 5

A CIEE evaluator is designing an overhead shelf at a seated workstation. To avoid shoulder elevation above 60°, items stored on the shelf should not require reach higher than approximately:

Accepted Answer

Shoulder height

Answer

Shoulder height is the upper bound for frequently accessed items; reaching beyond shoulder height elevates the humerus above 60°, increasing supraspinatus impingement risk.
