IHSA Risk Analysis & Hazard Identification 2

Question 1

Which risk assessment matrix dimension combines likelihood and consequence to produce a risk rating?

Accepted Answer

Probability vs. severity

Answer

Risk rating matrices plot probability of occurrence against severity of consequence to prioritize hazards.

Question 2

A Job Hazard Analysis (JHA) is BEST described as:

Accepted Answer

A step-by-step breakdown of a task to identify hazards at each step

Answer

A JHA systematically examines each step of a job task to identify associated hazards and controls before work begins.

Question 3

In the hierarchy of controls, substitution means:

Accepted Answer

Replacing a hazardous material or process with a less hazardous one

Answer

Substitution involves replacing the hazard source with something that presents lower risk.

Question 4

Which technique uses structured 'What-If' questioning to systematically identify potential failure scenarios?

Accepted Answer

What-If Analysis

Answer

What-If Analysis uses structured brainstorming questions to explore deviations and failure scenarios.

Question 5

A near-miss incident is most valuable to safety management because it:

Accepted Answer

Reveals hazards and system weaknesses before they cause injury

Answer

Near-misses expose latent hazards and control failures, providing a free opportunity to prevent future incidents.
