  • Updated 02/2011 CS
  • Stress point of being proactive on all three protection strategies even if the fire is several miles away.
  • Burnout and beat tactics should be discussed when h2o in not close to point being protected.
  • Fuel mix for pumps may vary by region.
  • Discuss several methods for sprinkler layout while stressing that every cabin is different and no set standard can be made to cover all situations one may encounter. The key is to wet the entire structure including the the roof and ground near the cabin. Sprinkler heads most commonly will be adjusted to spray 360 degrees.
  • There are several other way to set up sprinklers and many require the use of a double female hose fitting. The key point to stress is to ensure that each sprinkler head has adequate pressure to accomplish the task at hand. Rule of Thumb: Each sprinkler head has a dedicated 5/8 in. hose to supply water.
  • There are several notch variations that should be discussed.
  • Be flexible, be creative and be proactive.
  • Cabin Point Protection in Alaska

    1. 1. Point Protection in Alaska “cabin protection”
    2. 2. What is point protection? • Protection of a site threatened by a fire. • A site can be: – A single structure – A compound of structures – Materials – Historical/Archeological sites – Allotments – Antennas – Pipeline – Protected habitat
    3. 3. Structures “cabins” • Cabin/structure protection is the most common type of point protection in Alaska. • Cabins vary greatly in scale and construction. Most cabins can be categorized somewhere between: – Maintained – Historical
    4. 4. Maintained
    5. 5. Historical
    6. 6. Develop a plan • Protection strategy: – Plumb and defend – Plumb and run – Burn out and mop-up • Considerations: – Time – Fuels – Number of structures – Available resources – Availability of supplies – Is cabin occupied? • Triage
    7. 7. Plumb and defend • Pros: – Personnel on site • Spot fires • Pre-wetting • Site prep – Burnout • may /may not be necessary – Pumps/sprinklers • adjusted as needed. – After the fire has passed • equipment and personnel may be pulled from site
    8. 8. Plumb and defend • Cons: – Resources • committed to structure(s) for long periods of time • resupply – Fire • threaten multiple structures at same time
    9. 9. Plumb and run • Pros: – Minimal people • protect multiple cabins – Uses • fire is far from cabins • Several cabins and fire is close • Lack of resources to staff each cabin • No adequate safety zone
    10. 10. Plumb and run • Cons: – Pump/sprinklers • System may fail • Pump gas runs out before fire reaches cabin – Smoke/time considerations • resources may not return in time to start pumps – Equipment needs to be retrieved at a later date
    11. 11. Burn out and mop-up • Pros: – Black to secure cabin – No water needed – Great in tundra – No need to return to pull equipment – Resources on scene to deal with problems during burnout operations – Talk with FMO/ Agency Administrator before burning!!!!
    12. 12. Burn out and mop-up • Cons: – Fire • may never reach site • Later spotting into unburned fuels – Loss of aesthetic value – Dirty burn may not be effective – Trees falling on cabin – Possible lengthy mop-up
    13. 13. Cabin wrap • Not commonly used anymore • Not very effective • No need for cabin wrap if sprinklers are available • Labor intensive to install • Must be removed • Damage to structures(staples and tacking) • Require ladders for installation
    14. 14. Site preparation • Clear out wood and slash piles near structure. • Cut trees – bucked and stacked – limbs scattered – Thin and limb larger trees • Scatter problem dead and down( if you can’t, then sprinkler the piles) • Trench around cabin • Clear enough to accomplish the job, but remember why people have cabins in the woods!
    15. 15. Pumps Use the best pump for the job • Shindaiwa/ Honda – – Low on power. – Minimal fuel consumption – Generally less than 8 sprinklers – Best for set up and leave operations near H20. – Run time( 5 gal.) approx. 8 hrs. – 40:1 premix for both 2 stroke and 4 stroke • Mark III – – Lots of power, – Higher fuel consumption for set up leave operations. – Generally around 15 sprinklers – Best for cabins far from H2O or high on the hill. – Multiple structures – Run time (5 gal.) approx. 3 hours – 40:1 premix
    16. 16. Sprinkler kit • Sprinkler Kits contain (Alaska Fire Service) : – Shindaiwa fuel hose line 5 gal can adapter – 10 rolls / 50’ garden hose – 4 1” to ¾” reducers – 5 sprinkler heads – 5 gal. gas can(pump adapted) – 2 1” Y – 3 ¾” Y – 2 extra spark plugs – Length of “P” cord • Kit contents may vary by agency and region • One kit does not equal one cabin
    17. 17. Sprinkler installation • Use enough sprinklers to cover the entire structure. • Vary set up heights (example): 2 above roof line on opposite corners, 2 below roof line on the other opposite corners • Adjust sprinklers as needed: • short range mist • long range spray • Remove all kinks from 3/4” hose. • Adjust sprinkler head for desired coverage range.
    18. 18. Sprinkler installation cont. • Use sprinklers on any receptive fuels surrounding the cabin. • Make sure hose lays are protected from cabin to pump • Adapt Shindaiwa to run off 5 gal. gas can. • Take several pictures for the zones/land managers • If pumps are left on a river/tidal waters, move the pump and fuel above the high water mark. • Don’t forget the out buildings!
    19. 19. Sprinkler installation cont. Do not set sprinklers up in a series connected with 5/8” hose (as shown below) the pressure loss is too great and the last sprinkler will have little to no pressure. Sprinklers Pump 1 ½ “ – 1” hose 3/4” hose
    20. 20. Sprinkler installation cont. • Run each sprinkler off of one section of garden hose attached directly to one inch or larger hose. (see below) Gated wye Sprinkler ¾”hose Pump Pump 1 ½ “ – 1” hose 1 ½ “ – 1” hose 1” hose
    21. 21. Sprinkler installation cont. Multiple sprinklers off gated wye
    22. 22. Sprinkler installation cont. Tripod Pole
    23. 23. Sprinkler installation cont. Tripod on roof Check coverage
    24. 24. Sprinkler installation cont. • Cut and notch method – Saw Cuts – hose perpendicular to cut – V notch to prevent sprinkler from rotating when charged – Lash tightly
    25. 25. Set-up • Always test the system! – Adequate coverage – Sprinkler tripods/poles are secure and stable – Pre wet area – Note best pump throttle setting – Note run time on 5 gal. Fuel Sprinklers wetting all sides of cabin
    26. 26. Make a map • GPS coordinates for: – Cabin – Pumps • Pump property numbers • List of supplies on site • List of site prep. completed • Map structures especially if several structure in close area ie. around a lake • List any additional supplies needed
    27. 27. Additional supply needs • • • • • Extra pump fuel Extra hose Extra pump Burning supplies Water and food (very common to be smoked in for days with no resupply) • Transportation?? – Local boat rental – Zodiac via paracargo (with or without operator) – ATV rental
    28. 28. Extended time between set-up and use • Always test pump and hose system. • Move pump, hose, fuel and all equipment above high water line. • If freezing temperatures are possible drain pump and hose.
    29. 29. Cabin etiquette • Be respectful of others property • Pick up your trash • Don’t eat any stored food • Leave things as you found them • Leave a note • Remember, someone may depend on the cabin regardless of its condition.
    30. 30. Common watch outs • • • • • • Nails in trees Old outhouse holes Unstable roof Fuel/hazmat Explosives Bear deterrents: – Plywood and nails – Plywood and large treble hooks – Etc……..
