Job Safety Analysis Interview Questions and Answers
Job Safety Analysis (JSA), also called Job Hazard Analysis (JHA), is a systematic process to identify hazards and control measures for specific jobs or tasks. It’s a key tool for preventing accidents and training workers.
This guide covers 50 JSA Interview Questions and Answers divided into short answer, long answer, and scenario-based questions.
🔹 Section 1: Short Answer Questions (15 Examples)
Q1. What is a Job Safety Analysis (JSA)?
A step-by-step review of a job or task to identify hazards and determine control measures.
Q2. Why is JSA important?
It helps prevent incidents, improves training, and ensures compliance with safety regulations.
Q3. What are the main steps of a JSA?
Select job → Break into steps → Identify hazards → Determine controls → Review with workers.
Q4. Who should participate in JSA?
Supervisors, workers performing the task, and safety professionals.
Q5. What is the difference between JSA and risk assessment?
JSA focuses on specific tasks step-by-step; risk assessment can be broader and activity-based.
Q6. When should a JSA be conducted?
For new jobs, after incidents, for high-risk tasks, or when changes occur.
Q7. How often should JSA be reviewed?
Regularly and whenever job conditions change.
Q8. What is meant by “critical job” in JSA?
A job with high potential for injury or serious consequences.
Q9. Why involve workers in JSA?
They know the job best and can identify hazards others may miss.
Q10. What are control measures in JSA?
Actions to eliminate or reduce hazards — engineering, administrative, or PPE.
Q11. How does JSA help in training?
It provides step-by-step safe work instructions for new employees.
Q12. What documentation results from a JSA?
A completed JSA form with job steps, hazards, and controls.
Q13. What is the role of a supervisor in JSA?
Lead the analysis, involve workers, implement controls, and monitor compliance.
Q14. Why prioritize high-risk jobs for JSA?
To address the most hazardous tasks first and maximize impact.
Q15. How does JSA support continuous improvement?
Lessons learned feed into updated procedures and safer methods.
🔹 Section 2: Long Answer Questions (15 Examples)
Q16. Explain the process of conducting a JSA.
Select a job, observe the task, break into steps, identify hazards, determine controls, review with employees, and document.
Q17. Describe how to select jobs for JSA.
Use criteria like accident history, potential severity, and new or changed tasks.
Q18. Discuss the hierarchy of controls in JSA.
Eliminate hazards first, then substitute, engineering controls, administrative controls, and PPE.
Q19. How to ensure worker participation in JSA?
Involve them in hazard identification, encourage open discussion, and recognize contributions.
Q20. Explain the difference between proactive and reactive use of JSA.
Proactive prevents incidents before they occur; reactive investigates after incidents to improve procedures.
Q21. How to integrate JSA into permit-to-work systems?
Use JSA findings to inform permit conditions and controls.
Q22. What documentation should be maintained for JSAs?
Completed JSA forms, review dates, participants, and updates.
Q23. How to train employees on JSA?
Workshops, on-the-job demonstrations, and reviewing actual JSAs.
Q24. Discuss common mistakes in JSAs.
Too few job steps, vague hazards, not updating, lack of worker input.
Q25. How can technology improve JSAs?
Digital JSA apps, hazard libraries, and analytics.
Q26. Explain how to verify effectiveness of JSA controls.
Observe job performance, inspect controls, and track incident trends.
Q27. Describe how to handle multi-employer work using JSA.
Conduct joint JSAs, coordinate controls, and communicate roles.
Q28. How to incorporate near-miss data into JSAs?
Review near misses to identify additional hazards and controls.
Q29. Explain using JSAs for training contractors.
Provide JSA forms and review hazards before work starts.
Q30. How to ensure JSAs remain relevant?
Review periodically, after incidents, and when equipment or processes change.
🔹 Section 3: Scenario-Based Questions (20 Examples)
