Activation for mobilization is generally guided by what kind of thresholds?

• A. Activation thresholds are predefined and guided by the HIRA risk scores.
• B. Activation occurs randomly.
• C. Thresholds are determined by public opinion.
• D. There are no thresholds; activation is immediate for any event.

Answer: (A)

Activation for mobilization is guided by predefined thresholds based on risk assessment tools like HIRA risk scores. These scores evaluate how likely a hazard is and how severe its consequences could be, then categorize the situation into risk levels. When the observed event crosses the established thresholds, activation is triggered in a consistent, evidence-based way. This avoids overreacting to minor events or underreacting to serious ones, and it helps allocate resources where they’re actually needed.

Activation isn’t random, isn’t driven by public opinion, and isn’t without thresholds. Those other options would lead to unpredictable, inefficient, or reactive responses that aren’t sustainable or appropriate for planned mobilization.
