The closest Canadian equivalent to Fire Behavior Index (FBI) is Head Fire Intensity (HFI), which quantifies fire severity and its impact on suppression efforts. HFI is calculated using the rate of spread, fuel consumption, and heat of combustion, expressed in kilowatts per meter (kW/m). Like FBI, HFI can be categorized into threshold-based fire intensity classes to support fire behavior assessments and operational safety measures. However, the thresholds differ between the two systems due to variations in fuel types and the specific environments they represent.
