✍️ Sample CPE Questions & Answers
1. What is 'contact stress' in ergonomics?
Contact stress occurs when a hard surface or edge concentrates mechanical pressure on a small area of soft tissue, impairing circulation and nerve function.
2. Body mass index (BMI) is relevant to ergonomic design primarily because elevated BMI is associated with:
Higher BMI is associated with greater soft tissue bulk beyond what skeletal measurements predict, requiring adjustments to seat width, armrest spacing, and workspace clearances to accommodate larger body girths.
3. How can task design be modified to improve ergonomics?
Task design in ergonomics involves analyzing and restructuring work processes to make them less physically demanding and more efficient. This can include reducing repetitive motions, minimizing heavy lifting, optimizing reach distances, or incorporating micro-breaks. By modifying tasks to better suit human capabilities, it reduces physical strain, prevents injuries, and enhances overall worker comfort and productivity.
4. What is 'inattentional blindness' in human factors?
Inattentional blindness occurs when an individual fails to perceive an unexpected but visible stimulus because attention is directed toward another task.
5. Which posture assessment tool specifically accounts for both upper and lower body posture including load and activity type?
REBA (Rapid Entire Body Assessment) evaluates whole-body posture including upper and lower extremities, load handled, and activity level.
6. Why is employee training an essential part of ergonomic interventions?
Employee training is a cornerstone of effective ergonomic interventions because even the best-designed workstation can be misused without proper knowledge. Training teaches employees how to adjust their equipment, maintain good posture, recognize early signs of discomfort, and incorporate micro-breaks. This empowers them to actively participate in their own well-being and significantly reduces the risk of work-related injuries.
