Safety Trained Supervisor Job Safety Analysis Questions and Answers 1 — Questions and Answers
Question 1: During a JSA for a welding task, the team identifies a fire hazard from sparks. They immediately recommend that the welder wear fire-retardant clothing. According to the hierarchy of controls, what potential weakness does this JSA exhibit?
- The team immediately relied on PPE without considering higher-level controls. (Correct answer)
- The JSA should not have been conducted for a common task like welding.
- The team focused on a real hazard instead of a theoretical one.
- The JSA was performed by a team instead of a single expert.
Correct answer: The team immediately relied on PPE without considering higher-level controls.
A common mistake in developing JSAs is jumping directly to Personal Protective Equipment (PPE) as the primary control measure. The hierarchy of controls prioritizes more effective controls like elimination, substitution, or engineering controls (e.g., using welding blankets or screens) before resorting to administrative controls or PPE.
Question 2: A safety supervisor has limited time and resources to conduct Job Safety Analyses. Which of the following jobs should be prioritized?
- A routine office data entry task performed daily.
- A newly created maintenance task involving unfamiliar equipment. (Correct answer)
- A janitorial task that has been performed without incident for 10 years.
- A landscaping task involving planting flowers in a pre-prepared garden bed.
Correct answer: A newly created maintenance task involving unfamiliar equipment.
Jobs with the highest risk should be prioritized for a JSA. This includes new or modified tasks, jobs with a history of injuries, and non-routine tasks. A new task with unfamiliar equipment presents a high degree of unknown risk and has the greatest potential for severe injury.
Question 3: A supervisor is leading a team to develop a JSA for changing a flat tire on a delivery truck. When breaking the job down into distinct steps, what is a key principle they should follow?
- Keep the sequence of steps in the correct order of occurrence. (Correct answer)
- Combine as many actions as possible into a single step to save time.
- Make the steps overly detailed, including every single turn of a wrench.
- Only list the steps that involve using Personal Protective Equipment (PPE).
Correct answer: Keep the sequence of steps in the correct order of occurrence.
Breaking a job down into its sequential steps is a critical part of the JSA process. Maintaining the correct order is essential to accurately identify how hazards are introduced and how one step might affect the safety of the next. Steps should be distinct but not overly detailed.
Question 4: What are the three fundamental components that form the basis of a standard Job Safety Analysis document?
- Incident Reports, Worker Complaints, OSHA Standards
- Time Study, Motion Analysis, Productivity Goals
- Task Steps, Potential Hazards, Control Measures (Correct answer)
- Personal Protective Equipment, Emergency Procedures, First Aid Stations
Correct answer: Task Steps, Potential Hazards, Control Measures
A JSA is a systematic process that involves breaking a job into a sequence of steps, identifying the potential hazards associated with each step, and then determining the control measures needed to eliminate or reduce those hazards.
Question 5: Once a Job Safety Analysis is completed and documented, what is its primary use in a day-to-day safety program?
- As a disciplinary tool to punish workers who deviate from procedures.
- As a confidential management document for liability purposes only.
- As a tool for developing safe work procedures and training workers. (Correct answer)
- As a replacement for conducting regular workplace inspections.
Correct answer: As a tool for developing safe work procedures and training workers.
The completed JSA is a valuable resource that forms the basis for creating standardized, safe work procedures. It is also an excellent training tool for new and experienced employees, ensuring everyone understands the hazards and required controls for a specific task.
Question 6: Which of the following is the MOST significant benefit of involving employees who regularly perform the task in the JSA process?
- It fulfills a regulatory requirement without needing supervisor input.
- It is the fastest way to complete the JSA document.
- It allows management to assign blame if an incident occurs later.
- It provides the most accurate and detailed understanding of the task's hazards. (Correct answer)
Correct answer: It provides the most accurate and detailed understanding of the task's hazards.
Involving experienced workers is crucial for a successful JSA. They bring practical, hands-on knowledge of the job's steps, potential hazards, and existing workarounds that a supervisor might not be aware of, which leads to a more accurate and effective analysis.
