Which step involves estimating the probability of exposure or occurrence within the risk assessment process?

• A. Identify Hazard
• B. Determine Severity
• C. Estimate Probability
• D. Make Judgment

Answer: (C)

Estimating probability focuses on quantifying how likely it is that people will be exposed to a hazard or that a particular adverse event will occur. This step is essential because risk is often viewed as a function of both how severe the outcome could be and how likely it is to happen, so the probability of exposure feeds directly into the overall risk characterization.

Identifying hazards is about spotting what could cause harm, not about how likely exposure is. Determining severity looks at the potential consequences if exposure occurs, not the chance of exposure. Making judgments involves interpreting the evidence and deciding on risk levels or actions, which comes after estimating probability and severity.
