Risk Analysis & Hazard Identification Flashcards

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

Answer: Probability vs. severity

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

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

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

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

In the hierarchy of controls, substitution means:

Answer: Replacing a hazardous material or process with a less hazardous one

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

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

Answer: What-If Analysis

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

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

Answer: Reveals hazards and system weaknesses before they cause injury

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

Which of the following best defines a 'latent hazard' in infrastructure environments?

Answer: A hidden or dormant condition that may not cause harm until triggered by another event

Latent hazards lie dormant in systems and are often revealed only when combined with other failures or triggering events.

During a site walkthrough for hazard identification, the IHSA recommends involving front-line workers primarily because:

Answer: Workers have direct knowledge of actual conditions and task-specific hazards

Front-line workers possess first-hand knowledge of real working conditions that may not be visible to supervisors or safety professionals.
