COSS Job Safety Analysis (JSA) 2

Question 1

Which criterion should be used FIRST when prioritizing which jobs to analyze with a JSA?

Accepted Answer

Jobs with the highest injury or illness frequency

Answer

Jobs with the highest injury or illness frequency should be prioritized first to address the greatest risk exposure.

Question 2

In a JSA, what does 'potential hazard' mean in the context of each job step?

Accepted Answer

Any condition or act that could cause injury, illness, or property damage

Answer

A potential hazard is any condition or act in a job step that could foreseeably cause harm, even if no incident has occurred yet.

Question 3

When conducting a JSA, who should ideally be involved in the process besides the safety professional?

Accepted Answer

The workers who actually perform the job

Answer

Workers who perform the job have firsthand knowledge of actual hazards and should be actively involved in the JSA process.

Question 4

What is the primary purpose of breaking a job into sequential steps during a JSA?

Accepted Answer

To identify hazards associated with each specific action in the task

Answer

Breaking a job into steps allows analysts to associate specific hazards with each discrete action, making hazard identification more thorough.

Question 5

A JSA reveals that a worker must lift a 75-pound box from floor level. Which control should be recommended FIRST under the hierarchy of controls?

Accepted Answer

Substitution with a lighter material

Answer

Substitution (replacing the heavy box with a lighter material or smaller units) is preferred over engineering controls because it eliminates the hazard at the source.
