  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
