Which of the following are the three key factors in the risk assessment process?

The correct choice highlights the essential components of the risk assessment process in hazardous materials operations. Hazard identification involves recognizing potential dangers associated with various substances and situations, which is crucial for understanding what risks exist. Exposure assessment evaluates how people, property, and the environment could be affected by these hazards, considering factors such as proximity and potential for interaction with hazardous materials. Finally, risk characterization synthesizes the information gathered from the previous two components to provide a clear picture of the risk, including the likelihood and consequences of exposure to the hazard.

These elements are integral to effectively managing risks in hazardous materials scenarios, enabling responders to make informed decisions and develop appropriate response strategies. This thorough approach ensures that all potential impacts are considered, facilitating a comprehensive understanding of the situation and guiding prevention and mitigation efforts.
