Which of the following BEST describes the difference between a JSA and a standard operating procedure (SOP)?
Answer: A JSA focuses on identifying hazards and controls, while an SOP focuses on correct procedural steps
A JSA is a hazard-identification and control document, whereas an SOP describes the correct method to perform a task regardless of hazard analysis.
During a JSA observation, a safety professional notices a worker using an undocumented shortcut. What is the correct action?
Answer: Document the shortcut as a job step and evaluate its associated hazards
Real work practices, including shortcuts, represent actual hazard exposure and must be documented in the JSA to ensure accurate hazard identification.
Which type of hazard is MOST likely to be overlooked if a JSA is conducted only by reviewing written procedures rather than direct observation?
Answer: Behavioral and ergonomic hazards from actual work practices
Behavioral and ergonomic hazards arising from real worker movements and habits are invisible in written procedures but apparent during direct observation.
In JSA terminology, what is an 'unsafe act'?
Answer: A human behavior that deviates from a safe procedure and increases risk of injury
An unsafe act is a human behavior—such as bypassing a guard—that deviates from accepted safe practice and elevates injury risk.
A JSA for a confined space entry would MOST importantly address which hazard category?
Answer: Atmospheric hazards including oxygen deficiency and toxic gases
Atmospheric hazards are the leading cause of confined space fatalities and must be the primary focus of a confined space entry JSA.
Which statement about JSA training is most accurate?
Answer: Workers should be trained on the JSA before performing the job for the first time
Workers must understand the hazards and controls identified in the JSA before starting the job to prevent initial incidents.
When a new piece of equipment is introduced to a workplace, which action is MOST appropriate regarding existing JSAs?
Answer: Review and update all JSAs that involve tasks using the new equipment
New equipment can change hazard profiles for multiple jobs, so all affected JSAs must be reviewed and updated to reflect new risks and controls.
