Presentation Transcript

  1. Fuels and Fire Behavior(Optional)

  2. OBJECTIVES • Identify key elements of the fire environment: • Fuels • Weather • Topography • Fire behavior • Discuss how the fire environment influences burn execution

  3. Pre-burn Reconnaissance Key participants • Pilot • Burn Boss/Ignition Specialist

  4. Pre-burn Reconnaissance • A thorough recon of the burn area and a discussion of the burn objectives are essential to a successful firing operation. • Fire environment elements to consider during the recon are:

  5. Pre-burn Reconnaissance: Fuel Characteristics • Type and loading • Continuity • Fuel moisture • Chemical properties • Fuel size, shape, and compactness • Vertical arrangement and horizontal continuity

  6. Pre-burn Reconnaissance:Weather Factors • Temperature • Relative humidity • Inversions • Frontal passages • Winds • direction • speed • duration • local influences • Recent and expected precipitation

  7. Pre-burn Reconnaissance:Topography • Slope • Aspect • Elevation • Local influences • canyons • lakes • mountains • glaciers

  8. Pre-burn Reconnaissance:Fire Behavior • Fire types • surface • crown • Fire growth characteristics • head fires • backing fires • flanking fires

  9. Aerial Firing Ignition Patterns • Strip-head • Spot • Chevron • Center • Backing fire • Or a combination of the above

  10. Interaction • Fuels, weather, topography, fire behavior, and ignition pattern all interact to create fire effects. • Adjustments to firing patterns can be made to produce fire effects that will meet burn objectives.
