Question 1

Which workstation height range is generally recommended for seated computer work to minimize shoulder and neck strain?

Accepted Answer

23–28 inches from the floor

Answer

A seated desk height of roughly 23–28 inches from the floor supports neutral elbow and shoulder posture for most adults.

Question 2

When designing a workstation for a standing worker performing precision assembly, the work surface should ideally be positioned at what height relative to the elbow?

Accepted Answer

5–10 cm above elbow height

Answer

For precision tasks requiring fine motor control, the work surface is placed slightly above elbow height to allow visual access without excessive neck flexion.

Question 3

Which engineering control is the HIGHEST priority in the hierarchy of ergonomic interventions?

Accepted Answer

Elimination or substitution

Answer

Elimination or substitution removes the hazard at the source and is always preferred over lower-hierarchy controls like training or PPE.

Question 4

A neutral wrist posture during keyboard use is best described as:

Accepted Answer

Wrist in a straight, flat position

Answer

A straight, flat wrist alignment minimizes tendon compression and carpal tunnel pressure during prolonged keyboard work.

Question 5

Which type of chair adjustment is MOST critical for supporting proper lumbar lordosis in prolonged seated work?

Accepted Answer

Lumbar support height

Answer

Lumbar support height adjustment ensures the support aligns with the natural inward curve of the lower back, reducing disc pressure.
