Which of the following indicates a misguided approach to battling a fire?

Building fireline downhill with the fire below indicates a misguided approach because it places firefighters in a perilous position. When constructing a fireline, the goal is to create a barrier that can stop the fire's progression while ensuring the safety of the personnel involved. Building uphill is generally considered safer because it enables firefighters to control the situation better and allows for safer escape routes if necessary.

When a fire is below the fireline, heat and flames can rise and create erratic fire behavior, especially if the wind shifts. Fire can also spot or create new ignitions ahead of the fireline, which could compromise the safety of firefighters working on the line. Thus, building downhill with the fire beneath poses significant safety risks and challenges in effectively controlling the fire.

In contrast, utilizing aerial support, establishing a secure perimeter, and approaching fires from a distance are standard practices that leverage safety and strategic effectiveness in fire management. These approaches allow firefighters to assess the situation, implement control measures, and protect themselves and the public efficiently.
