  1. Managing the Burn:Firing techniques and managing ignition for fire effects

  2. FIRING CONSIDERATIONS • Desired fire behavior • Topography • Wind changes through the predicted burn period • Crew safety • Firing methods • Smoke management

  3. FIRING TECHNIQUES • Back fire • Strip fire • Spot fire • Flank fire • Ring fire • Head fire

  4. Back Firing • Where Used: Understory Burning, Heavy Fuels, Near Control Line, Smoke Sensitive Areas. • Advantages: Low Intensity, Low Scorch, Minimal Spotting Potential, High Consumption. • Disadvantages: Slow, Poor Dispersion.

  5. Strip Head Firing • Where Used: Large Units, Shrublands, Grasslands. • Advantages: Fast, Flexible, Can Adjust Intensity. • Disadvantages: Requires Access to the Unit, Fires Will Interact.

  6. Spot Head Firing • Where To Use: Large Units, Units With Dispersed Fuels, Understory Burns. • Advantages: Fast, Intensity Highly Adjustable, Variable Fire Behavior. • Disadvantages: Need Access to the Unit.

  7. Flank Firing • Where Used: Shrublands, Light Fuels. • Advantages: FL Between Backing and Head Fire Behavior, Easily Modified. • Disadvantages: Susceptible to Wind Shifts, Requires Experience Firing Personnel.

  8. Ring Firing • Where Used: Shrublands, Brush Piles, Clearcuts. • Advantages:Fast, Excellent Smoke Dispersal, Very High Intensity, Good Draw. • Disadvantages: Strong Convection Column May Develop, Spotting Potential May be High.

  9. Head Firing • Where Used:Large Units, Shrublands, In Communities with Light Fuels. • Advantages:Fast, Inexpensive, Good Smoke Dispersal. • Disadvantages:High Intensity, Greater Spotting Potential, Larger Volume of Smoke Generated.

  11. IGNITION METHODS

  12. Firing: Methods and Techniques

  13. Head Fire : Portion of the fire burning with the wind or up-slope

  14. Flanking Fire: • Portion of the fire burning at right angles to the wind or slope Flank Fire:Portion of the fire burning at right angles to the wind or slope

  15. Strip-Head Firing

  16. Spot-Head Firing (Grid or point source ignition)
