Name the fire phase described: Fire is virtually free burning and has plenty of fuel?
Name the fire phase described: Fuel package has been mostly consumed and heat release rate drops.
Name the fire phase described: Heat generated from the ignition now begins to cause heat transfer to surrounding combustibles.
Name the fire phase described: In most cases, the fire is small and limited.
Name the fire phase described:Small pockets of fire may still exist as the fuel slowly moves to the point of total consumption.
