Which terms describe the two categories used when assessing hazards?

• A. Impact and feasibility.
• B. Urgency and frequency.
• C. Severity and probability.
• D. Risk level and exposure.

Answer: (C)

In hazard assessment, you evaluate risk using two dimensions: severity of impact and probability of occurrence. Severity describes how bad the outcome could be if the hazard materializes—injury, damage, downtime, or environmental harm. Probability measures how likely the hazard is to occur within the given situation or timeframe. Together, these two factors determine the overall risk level and guide what controls or mitigations are needed.

Other pairings don’t align with the standard two-factor way we assess hazards. Feasibility or urgency aren’t the primary dimensions of risk in this context, and while frequency touches likelihood, it doesn’t pair with impact in the same framework. Risk level and exposure describe outcomes and context rather than the two core dimensions used to gauge hazard severity and likelihood.
