In incident risk assessment, what distinguishes terrorist incidents from natural disasters?

• A. They generally occur without human intention and lack deliberate targeting of responders.
• B. Terrorist incidents may involve secondary devices or intentional targeting of responders.
• C. Natural disasters are always caused by weather systems.
• D. Natural disasters never involve mass casualties.

Answer: (B)

Terrorist incidents introduce the possibility of additional threats and a deliberate effort to target responders, and that shapes how risk is assessed on the scene. The idea of secondary devices means danger can persist after the first event, so safety plans must account for hidden or delayed threats, expanded danger zones, and procedures to avoid triggering further harm. Deliberate targeting of responders changes the dynamic of scene management: rescue teams may themselves become targets, requiring close coordination with law enforcement, robust scene control, rapid risk reassessment, and protective measures for personnel.

Natural disasters, while capable of causing mass casualties, are not driven by intent to harm and do not involve deliberate targeting of responders. They may be caused by weather or geological processes, and the presence of secondary devices or intentional attacker patterns is not part of the risk picture. That combination—secondary threats and targeted harm to responders—is what distinguishes terrorist incidents in incident risk assessment.
