S-290 Unit 11: Extreme Wildland Fire Behavior covers the characteristics and contributing factors of extreme fire conditions. Fire activity that is considered extreme includes crown fire, spotting, fire whirls, and wind-driven or plume-dominated fires. Description of what determines the probability of ignition of a fire is also included. This module is part of the Intermediate Wildland Fire Behavior Course.
Describe the four common denominators of fire behavior on tragedy wildland fires.
Describe extreme fire behavior characteristics and recognize fire environment influences that contribute to extreme fire behavior.
Describe the three stages of crown fire development and identify the key factors and indicators leading to crown fire development.
Identify the three factors that contribute to the spotting problem and describe the conditions associated with each factor.
Define the probability of ignition, describe its use, and determine it using tables.
Define fire whirls (vortices), the conditions under which they are likely to develop, and their implications to wildland fire behavior.
Explain the difference between wind-driven and plume-dominated fires
