When dealing with a Level III incident, evacuation of people will cover an area of:

• A. several square blocks
• B. Large scale evacuation
• C. one mile upwind
• D. one block in each direction

Answer: (B)

Level III hazmat incidents require large-scale protective actions. When the release is severe, authorities evacuate a broad area to reduce exposure, often spanning many blocks or even miles, with coordinated shelters and traffic planning. This mass evacuation reflects the potential for widespread contamination and the need to get people out of the plume’s path quickly. The other options describe much smaller or mismatched boundaries. Evacuating only a few blocks or one block in each direction isn’t enough for a Level III event, and evacing one mile upwind doesn’t make sense because contaminants travel with the wind downwind, not upwind. Therefore, the best fit is a large-scale evacuation.
