Which is a recommended action to take in the event of a pesticide fire?

In the event of a pesticide fire, constructing berms to contain contaminated runoff water is a recommended action because it helps prevent the spread of toxic materials. Pesticides can be hazardous to the environment, and runoff from the area of the fire can contaminate nearby water sources. By creating berms, you can effectively contain any runoff that may occur due to the fire, limiting environmental harm and making it easier for emergency responders to manage the situation.

This preventative measure aligns with best practices for environmental protection during hazardous incidents. It focuses on maintaining safety and environmental integrity while allowing professional firefighters to deal with the fire itself, which is critical given the complexities and dangers posed by pesticide fires.
