S-290 Unit 1: The Fire Environment examines the components of the fire environment triangle and how each affects fire behavior. As part of this topic, heat transfer mechanisms and firebrand transport and the contribution to fire behavior are included. Basic fire terminology is introduced and will be used throughout the course. Later units in the S-290 course will build upon material introduced in this module.

Upon completion of this unit, you should be able to: 1. Describe the three components of the wildland fire environment. 2. List and give examples of the three methods of heat transfer. 3. List three methods of mass transport of firebrands on wildland fire. 4. Explain the relationship between flame height/length and its relationship to the fireline intensity. 5. Describe primary environmental factors affecting ignition, fire intensity, and rate of spread of wildland fires. 6. Discuss the relationship of wildland fires of different intensities to their environments. 7. Describe the behavior of wildland fires using standard fire behavior terminology.
