Final answer:
Cascading events are incidents where one hazardous event leads to another and should be included in the hazard identification process of an emergency operations plan. These events can often not be entirely predicted or prevented, but planning can help mitigate their effects. Therefore correct option is B
Step-by-step explanation:
Cascading Events in Emergency Operations Plans
Cascading events occur when one hazardous event triggers another. An example is when an earthquake leads to a tsunami, which in turn may lead to a nuclear power plant failure. These cascading events should indeed be considered as part of the hazard identification process within an emergency operations plan. While complete prediction and prevention of such events may not be possible, having strategies in place as part of an emergency operations plan can mitigate the impacts. These plans should account for uncertainty and the complexity of dependent events such as natural disasters and their consequent effects on human society and infrastructure.
Considering the asymmetric risk when facing potential threats is significant—while Plan A might involve maintaining the status quo, Plan B could involve proactive, protective measures. Although false alarms may lead to criticism, the cost of inaction in the face of a real threat can be catastrophic, as shown by instances such as the Texas power grid failure during a freeze.
