Length-to to-Breadth (L/B) Ratio <strong>of</strong> <strong>Escape</strong> <strong>Fire</strong> Based on Canadian and Australian research, a 76% slope is deemed to be the equivalent to a wind speed <strong>of</strong> ~44 mph and a L/B ratio <strong>of</strong> 8:1 in grass fuels.
Length-to to-Breadth (L/B) Ratio vs. Elapsed Time Since Ignition L/B = 1.4 @ 30 seconds 120 ft divided by 1.4 = 86 feet wide at its maximum point
