5.2.9. Basic Wildfire Suppression Strategy and Tactics Copy – copy

Natasha Birsa

Main Stages in Wildfire Suppression

1) Initial Fire Assessment

  • Convey the situation to dispatch centre
  • Size-up the situation for resource requirements
  • Key concept is to project the fire situation you see now with the time lag of resource arrival
  • Common trap is getting behind the curve and playing catch-up
  • Fuels, consider fuels ahead of the fire
  • Weather, now and forecasted
  • Topography, operability, fire behaviour
  • Access Water availability
  • Resource availability
  • Burning period remaining
  • Daylight, flying time

2) Initial Attack

A) Direct Attack:
  • Working directly on the fire edge
  • No unburned fuel between control line and fire edge
  • Can be by aerial or ground resources

B) Indirect Attack
  • Used where fire intensity or spread rates preclude
  • Direct or Parallel Attack. A Back Fire is set some distance away from the wildfire to remove fuels.
  • Back Fire is anchored from a natural or man-made control line.
  • Extensive knowledge of fire behaviour required to carry out.

C) Parallel Attack
  • Fire intensity or spread rate precludes direct attack
  • Control line established away from fire edge
  • Fuels between control line and fire edge are removed by burning off from the control line, (burn off)
