Question 1

A worker reports neck pain after switching to a dual-monitor setup. Which adjustment should be made first?

Accepted Answer

Position the primary monitor directly in front and center both monitors symmetrically

Answer

The primary monitor should be centered in front of the user, with secondary monitors arranged symmetrically to minimize neck rotation.

Question 2

Which keyboard tray feature most directly reduces ulnar deviation during typing?

Accepted Answer

Negative tilt (front edge higher than rear)

Answer

A negative tilt positions the keyboard so wrists remain straighter, reducing ulnar deviation and flexion.

Question 3

Under ANSI/HFES 100 guidelines, the recommended luminance ratio between a computer screen and the immediately surrounding area should not exceed:

Accepted Answer

3:1

Answer

ANSI/HFES 100 recommends a maximum luminance ratio of 3:1 between the screen and immediately adjacent surfaces to prevent eye strain.

Question 4

A data-entry operator performs highly repetitive keying tasks for 6 hours daily. Which intervention addresses repetitive strain risk most comprehensively?

Accepted Answer

Implement micro-breaks every 20–30 minutes combined with task rotation

Answer

Micro-breaks combined with task rotation reduce cumulative loading on tendons and muscles more effectively than a single equipment change.

Question 5

When using a laptop as the sole workstation for extended periods, the highest-priority ergonomic intervention is:

Accepted Answer

Using an external keyboard and mouse with the laptop elevated to eye level

Answer

Elevating the laptop screen to eye level and adding external input devices eliminates the forced choice between good posture for the screen or for the hands.
