Which lighting condition is MOST likely to cause computer vision syndrome at a workstation?
Answer: Overhead fluorescent lighting directly above the monitor causing veiling reflections
Overhead fluorescent lights positioned directly above and behind a monitor create veiling reflections on the screen, forcing users to strain their eyes to see content.
A user reports that their chair's lumbar support causes discomfort. What should the ergonomics assessor evaluate FIRST?
Answer: Check if the lumbar support height aligns with the user's lumbar curve (L1-L5 region)
Lumbar support must be positioned to align with the natural inward curve of the lower back; misalignment is a common cause of discomfort.
What is the recommended seat pan depth adjustment for proper thigh support in an office chair?
Answer: Leave 2-3 finger widths of space between the front of the seat pan and the back of the knees
A 2-3 finger gap between the seat pan edge and the back of the knees prevents pressure on the popliteal area and maintains circulation.
In an ergonomic assessment, a user's wrists are dorsally extended while typing. What is the BEST immediate corrective action?
Answer: Lower the keyboard surface or tilt the keyboard to achieve neutral wrist position
Wrist extension during typing is directly caused by the keyboard being too high or positively tilted; adjusting keyboard height or tilt corrects the root cause.
Which factor is MOST important when selecting a sit-stand workstation converter versus a full height-adjustable desk?
Answer: Available desk surface area needed for all work tasks and equipment
Converters reduce available workspace when raised and may not accommodate all equipment, so the total workspace requirement should be the primary selection criterion.
What is the recommended temperature range for office workstations to support worker comfort and productivity?
Answer: 68-76°F (20-24°C)
ASHRAE standards recommend 68-76°F (20-24°C) for sedentary office work to maintain thermal comfort and cognitive performance.
A user has a touchscreen monitor and frequently reaches forward to interact with it. What ergonomic risk does this create?
Answer: Shoulder and neck strain from sustained forward reaching (Gorilla Arm Syndrome)
Repeatedly reaching forward to touch an upright screen causes shoulder fatigue and neck strain, commonly called 'Gorilla Arm Syndrome' in ergonomics literature.
