Moisture content thresholds for ignition and rate of fire More than 90 years of fire research shows that four factors working in concert can result in the type of catastrophic wildfires witnessed in 2000 and 2002: weather, an abundance of fuel (combustible forest materials), lack of moisture, and terrain characteristics. Take care with portable heat generating appliances such as irons, kettles and heaters. What factors cause firebrands to be lifted and ignite a spot fire. Although spotting may enhance the combined ROS, some spot fires may have little impact or may possibly reduce ROS by removing fuel ahead of the main fire [14, 15].Numerous factors potentially control how spot fires influence fire spread including main and spot fire ROS (pre-merging), fire intensity and size, number of spot fires, spotting distances [] and spot fire build-up times [].
