Safety Trained Supervisor Job Safety Analysis Questions and Answers 1

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?

Accepted Answer

The team immediately relied on PPE without considering higher-level controls.

Answer

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?

Accepted Answer

A newly created maintenance task involving unfamiliar equipment.

Answer

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?

Accepted Answer

Keep the sequence of steps in the correct order of occurrence.

Answer

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?

Accepted Answer

Task Steps, Potential Hazards, Control Measures

Answer

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?

Accepted Answer

As a tool for developing safe work procedures and training workers.

Answer

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.
