Which type of incident may require a combination of both shelter-in-place and evacuation strategies?

• A. A major flood with hazardous materials
• B. A localized chemical spill
• C. A meteorological event with anticipated low risk
• D. A power outage in an urban area

Answer: (A)

The incident involving a major flood with hazardous materials may require a combination of both shelter-in-place and evacuation strategies because floods often create complex scenarios where both immediate and long-term safety considerations are crucial. In such situations, certain areas may need to be evacuated to protect individuals from floodwaters potentially mixed with hazardous substances. Simultaneously, there may be locations that are not immediately at risk but could become unsafe if people are exposed to contaminants in the water.

Combining both strategies allows for a tailored response: evacuating those in immediate danger while advising others to shelter in place as a precautionary measure against potential hazards, like airborne toxins or further chemical exposure. This dual approach maximizes safety and minimizes the risk of panic and injury during a complicated and potentially dangerous event.
