When assessing risks at an incident scene, which two aspects are primarily evaluated?

When assessing risks at an incident scene, the focus is on understanding both the frequency and severity of those risks. Frequency pertains to how often a specific risk might occur, which helps in anticipating potential hazards and preparing appropriate responses. The severity measures the impact or consequences of a risk if it were to occur, allowing responders to gauge the potential harm to people, property, and the environment.

By evaluating both frequency and severity, emergency personnel can prioritize their resources and strategies to address the most significant risks effectively. This dual assessment is critical for ensuring a well-coordinated response and maximizing safety for both responders and the community affected by the incident.

In contrast, the other combinations of aspects do not provide a comprehensive understanding of risks in this context. While complexity and duration can be factors in specific scenarios, they do not capture the core elements of risk assessment as comprehensively as frequency and severity do.
