1.5 times

2.5 times

The correct answer is: 1.5 times

The minimum width of a fireline is generally established as 1.5 times the predominant fuel height. This guideline is crucial because it ensures that the fireline is wide enough to effectively contain the fire, considering various factors such as the type and height of vegetation, which can influence fire behavior. A fireline that is 1.5 times the fuel height provides sufficient space to remove combustible materials and reduces the risk of fire jumping over the line. Additionally, this width helps in creating a barrier that can withstand the heat and potential embers from the fire, while still allowing for access and safe operation of firefighting crews and equipment. Understanding this relationship between fireline width and fuel height is vital for effective fire suppression strategies in wildland firefighting.
