COSS Job Safety Analysis (JSA) 3

Question 1

Which of the following BEST describes the difference between a JSA and a standard operating procedure (SOP)?

Accepted Answer

A JSA focuses on identifying hazards and controls, while an SOP focuses on correct procedural steps

Answer

A JSA is a hazard-identification and control document, whereas an SOP describes the correct method to perform a task regardless of hazard analysis.

Question 2

During a JSA observation, a safety professional notices a worker using an undocumented shortcut. What is the correct action?

Accepted Answer

Document the shortcut as a job step and evaluate its associated hazards

Answer

Real work practices, including shortcuts, represent actual hazard exposure and must be documented in the JSA to ensure accurate hazard identification.

Question 3

Which type of hazard is MOST likely to be overlooked if a JSA is conducted only by reviewing written procedures rather than direct observation?

Accepted Answer

Behavioral and ergonomic hazards from actual work practices

Answer

Behavioral and ergonomic hazards arising from real worker movements and habits are invisible in written procedures but apparent during direct observation.

Question 4

In JSA terminology, what is an 'unsafe act'?

Accepted Answer

A human behavior that deviates from a safe procedure and increases risk of injury

Answer

An unsafe act is a human behavior—such as bypassing a guard—that deviates from accepted safe practice and elevates injury risk.

Question 5

A JSA for a confined space entry would MOST importantly address which hazard category?

Accepted Answer

Atmospheric hazards including oxygen deficiency and toxic gases

Answer

Atmospheric hazards are the leading cause of confined space fatalities and must be the primary focus of a confined space entry JSA.
