CEA Ergonomic Design & Intervention Strategies 1 — Questions and Answers
Question 1: Which intervention best reduces repetitive motion injuries at a manufacturing workstation?
- Add more lighting
- Increase production targets
- Introduce task rotation (Correct answer)
- Install surveillance cameras
Correct answer: Introduce task rotation
Automation or redesigning tasks to minimize repetitive motions can significantly reduce the risk of injuries.
Question 2: What design principle improves hand tool ergonomics?
- Use metal grips
- Favor smaller handles
- Ensure non-slip, cushioned grip with neutral wrist posture (Correct answer)
- Avoid adjustable tools
Correct answer: Ensure non-slip, cushioned grip with neutral wrist posture
Ergonomic hand tools reduce force requirements and maintain neutral wrist positions, which helps prevent strain.
Question 3: What is the most effective ergonomic solution for prolonged standing at a workbench?
- Wear taller shoes
- Use anti-fatigue mats (Correct answer)
- Install carpet tiles
- Adjust lighting above
Correct answer: Use anti-fatigue mats
Anti-fatigue mats and footrests reduce the strain on legs and lower back, improving worker comfort and safety.
Question 4: Which change would best improve ergonomics for computer users?
- Add a wrist brace
- Raise monitor to eye level (Correct answer)
- Use dual monitors
- Dim the screen brightness
Correct answer: Raise monitor to eye level
Adjusting monitor height so the top is at eye level encourages a neutral neck position and prevents strain.
Question 5: What role does employee training play in ergonomic intervention?
- Encourages overtime
- Improves team communication
- Prevents equipment theft
- Promotes safe work practices (Correct answer)
Correct answer: Promotes safe work practices
Training teaches proper posture, equipment use, and reinforces healthy work habits to prevent ergonomic-related injuries.
Question 6: How can adjustable workstations improve ergonomic design?
- Limit user control
- Increase screen size
- Support posture variability (Correct answer)
- Add background music
Correct answer: Support posture variability
Adjustable workstations allow users to customize their position, reducing strain and accommodating a wider range of users.
