Securing Control Line: Techniques for Effective Fire Management

This unit focuses on the vital methods for holding and securing control lines in fire situations. It emphasizes the importance of preventing slop-overs and effectively mopping up after ensuring the control line's integrity. Participants will learn about recognizing hotspots, protecting points of origin, trenching techniques, and fireproofing measures using gel and retardants. The course covers critical practices for effective mop-up, including identifying remaining hotspots, using water efficiently, and recognizing hazards such as snags. Proper techniques will help safeguard against re-ignition and ensure fire containment.

  1. Unit 7 - Securing the Control Line

  2. Objectives • Understand methods of holding and securing the control line to prevent slop-overs • Demonstrate methods of mopping up after the control line is secure • Explain about recognizing and protecting the point of origin

  3. Holding the Control Line • Heavy or overhanging fuels • Hillsides • Hot spots • Spot fires

  4. Trenching • This is digging a shallow trench with the berm on the downhill side • Any rolling material goes into the trench instead of all the way to the bottom of the hill

  5. Hotspotting • Areas of the line where fire is still active • Wind, radiant heat, spots, or falling material can jump the line

  6. Fireproofing • This is protecting risk fuels on the green side of the line • Foam gels, or retardant • Removing fuel

  7. Dozer Piles • You may need to break up piles that may have burning material inside • Don’t climb on top of piles

  8. Mopping up • This is putting out all remaining areas of fire and/or hotspots after the line around the fire is complete

  9. Pattern Systematic method of mop-up N Wind at 5 mph LCES Wet or Dry?

  10. Mop-up • Mop-up is killing all remaining hotspots or smoldering areas • Especially important to check areas near the control line • On large incidents, the fire may be gridded out into sections

  11. Mop-up Tips • If no hotspots are found, wait a few minutes and look for smoke • Look & listen for areas or spots • Feel for heat

  12. Mopping up with Water • Mix up some mud and stir in smoldering materials if water is short • If you have plenty of water, use straight streams to get into deep seated material

  13. Surface & Ground Mop-up • You may have to turn duff over several times to get all of the hot material exposed and out • Tree roots may be smoldering under the surface

  14. Snags • Burned trees with; • Fire above ground • Burned up branches • Leaning/unstable • Smoldering/burned roots • This is sawyer work; don’t attempt dropping this on your own • SNAGS WILL KILL YOU!

  15. Protecting the Point of Origin • The area where the fire started is likely to be the area of the most heat damage. • On most wildland fires, look for areas of hot white ash, this is usually your point of origin • Also look and compare burn damage in different areas • Protect the POO from damage from vehicles and foot traffic • Don’t let anyone tamper with the site

  16. Protecting the Point of Origin • Good clues include damage to foilage that doesn’t normally burn well

  17. Other clues that might help • Always be on the lookout for suspicious people nearby the fire area • Look around for any witnesses

  18. Look at This
