Which criterion should be used FIRST when prioritizing which jobs to analyze with a JSA?
Answer: Jobs with the highest injury or illness frequency
Jobs with the highest injury or illness frequency should be prioritized first to address the greatest risk exposure.
In a JSA, what does 'potential hazard' mean in the context of each job step?
Answer: Any condition or act that could cause injury, illness, or property damage
A potential hazard is any condition or act in a job step that could foreseeably cause harm, even if no incident has occurred yet.
When conducting a JSA, who should ideally be involved in the process besides the safety professional?
Answer: The workers who actually perform the job
Workers who perform the job have firsthand knowledge of actual hazards and should be actively involved in the JSA process.
What is the primary purpose of breaking a job into sequential steps during a JSA?
Answer: To identify hazards associated with each specific action in the task
Breaking a job into steps allows analysts to associate specific hazards with each discrete action, making hazard identification more thorough.
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?
Answer: Substitution with a lighter material
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.
How many job steps is generally considered optimal for a single JSA?
Answer: No fixed number; enough to capture all distinct hazard-creating actions
There is no fixed optimal number; steps should be defined as needed to capture every distinct action that could present a hazard without being so narrow that the JSA becomes unmanageable.
After a serious near-miss incident, when should the affected job's JSA be reviewed and updated?
Answer: Immediately, before the job is performed again
A near-miss indicates an uncontrolled hazard and the JSA should be reviewed and updated immediately before the job is repeated.
