Which workstation height range is generally recommended for seated computer work to minimize shoulder and neck strain?
Answer: 23–28 inches from the floor
A seated desk height of roughly 23–28 inches from the floor supports neutral elbow and shoulder posture for most adults.
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?
Answer: 5–10 cm above elbow height
For precision tasks requiring fine motor control, the work surface is placed slightly above elbow height to allow visual access without excessive neck flexion.
Which engineering control is the HIGHEST priority in the hierarchy of ergonomic interventions?
Answer: Elimination or substitution
Elimination or substitution removes the hazard at the source and is always preferred over lower-hierarchy controls like training or PPE.
A neutral wrist posture during keyboard use is best described as:
Answer: Wrist in a straight, flat position
A straight, flat wrist alignment minimizes tendon compression and carpal tunnel pressure during prolonged keyboard work.
Which type of chair adjustment is MOST critical for supporting proper lumbar lordosis in prolonged seated work?
Answer: Lumbar support height
Lumbar support height adjustment ensures the support aligns with the natural inward curve of the lower back, reducing disc pressure.
Which reach zone principle should guide placement of most-frequently used tools at a workstation?
Answer: Primary (normal) reach zone
Frequently used items should be placed in the primary reach zone — the area swept by forearms with elbows close to the body — to minimize awkward postures.
