ergonomics consultant Interview Questions and Answers

1. What is ergonomics?

   • Answer: Ergonomics is the scientific discipline concerned with understanding the interactions among humans and other elements of a system, and the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance.

2. Describe your experience in conducting ergonomic assessments.

   • Answer: [Tailor this answer to your own experience. For example: "I have conducted over 50 ergonomic assessments in various industries, including manufacturing, office settings, and healthcare. My assessments typically involve observation, interviews with workers, measurements of workstations, and the use of ergonomic assessment tools like the RULA and REBA checklists. I've identified and addressed issues ranging from improper posture to repetitive strain injuries, resulting in improved worker comfort, reduced injury rates, and increased productivity."]

3. What are some common ergonomic hazards you encounter?

   • Answer: Common ergonomic hazards include awkward postures (bending, twisting, reaching), repetitive movements, forceful exertions, vibration, contact stress (pressure points), and static postures (remaining in one position for extended periods).

4. Explain the difference between RULA and REBA assessments.

   • Answer: Both RULA (Rapid Upper Limb Assessment) and REBA (Rapid Entire Body Assessment) are observational checklist methods for assessing risk of musculoskeletal disorders. RULA focuses on the upper body (neck, shoulders, arms, hands), while REBA assesses the whole body, including the lower limbs and trunk. REBA is considered more comprehensive and incorporates more factors, including posture, force, and frequency of movement.

5. How do you prioritize ergonomic improvements?

   • Answer: Prioritization depends on several factors, including the severity of the risk, the number of employees affected, the feasibility of implementing improvements, and the cost-benefit analysis. I typically use a risk matrix to rank hazards and focus on addressing high-risk issues first. This often involves a combination of engineering controls (e.g., workstation adjustments), administrative controls (e.g., work rotation), and personal protective equipment (PPE) as a last resort.

6. What are some engineering controls for improving ergonomics?

   • Answer: Engineering controls involve modifying the workplace to reduce ergonomic hazards. Examples include adjusting workstation heights, using adjustable chairs, providing proper lighting, implementing automated equipment, redesigning tools to reduce force, and installing anti-fatigue mats.

14. How do you handle situations where management is resistant to implementing ergonomic changes?

    • Answer: I address resistance by presenting a strong business case for ergonomic improvements, highlighting the potential cost savings from reduced injury rates, increased productivity, and improved employee morale. I also demonstrate the return on investment (ROI) of ergonomic interventions.

15. What is your approach to communicating ergonomic findings and recommendations to clients?

    • Answer: I communicate findings clearly and concisely, using both written reports and presentations. Reports include visual aids (photos, diagrams) and prioritize recommendations based on risk and feasibility. Presentations are tailored to the audience (management, workers), emphasizing the practical implications of the recommendations.

16. Describe your experience working with different types of workers (e.g., office workers, factory workers, healthcare professionals).

    • Answer: [Tailor this to your experience. Example: "I have worked with a variety of workers, and my approach is always tailored to the specific demands of their jobs. For example, I understand that the ergonomic challenges faced by an office worker differ significantly from those of a factory worker or a nurse. My assessment methods and recommendations reflect these differences."]

17. What is your understanding of anthropometry and its role in ergonomics?
