  1. Wildland/Urban Interface Structure Protection

  2. Today’s Class • WAC 296-305-07001 thru 07019 • VRFA MOO 5521 Wildland Firefighting Safety, Tactics and Accountability • The Basics • Local Resources

  3. WAC 296-305-07001/19 • Defines “Wildland Fire” as: A fire burning in natural vegetation that requires an individual or crew(s) to expend more than one hour of labor to confine, control and extinguish. Agencies may substitute crews to avoid the one hour bench mark or increase crew size to complete the job in less than one hour. One hour was chosen as the maximum time that individuals should work in high temperatures in structural protective clothing.

  4. MOO 5521 • Defines “Brush Fire” as: A fire burning in natural vegetation that requires less than one hour of labor confine, control and extinguish.

  5. WAC 296-305-07001/19 • .07001- States Wildland gear will be provided by Employer • .07003- Defines type and uses of gear • .07005- Defines respiratory protection (currently there is no definition) • .07007- Accountability (ICS) • .07009- Wildland Apparatus • .07011- Restraints and Enclosures for apparatus • .07013- Equipment (hand tools) • .07015- Aircraft • .07017- First Aid • .07019- Training

  6. Types of gear • Structural Gear • 1 hour work time • Wildland Gear • Stored at 33 • Not for Structural FF

  7. Respiratory Issues • Wildland does not define level of respiratory protection • Common sense should prevail • Hazardous environment = SCBA

  8. VRFA Apparatus Type 1 apparatus • 1000 GPM Pump • 400 Gallon Tank Type 2 apparatus • 500 GPM Pump • 400 Gallon Tank

  9. Equipment • Chainsaws • Pulaskis • Shovels • Adze Hoes • Mcleod Tools

  10. MOO 5521 Wildland Interface&MOO 3606 PPE for Wildland • We are not going to review here • Fire orders • Watchouts • First Aid • Refers to all WACs • Appropriate Gear

  11. Structural Triage and Protection • The process of triaging and decision to protect structures threatened by a Wildland / Urban interface incident will rest with the I.C. There are several reasons weighed in this decision.

  12. Structural Triage and Protection • Size of the fire. • Inadequate resources. • Non-existent defensible spaces. • Absence of boxed in eaves. • Large unprotected decks. • Significant amounts of combustible storage.

  13. Structure Assessment Checklist • Address/Property Name • Numerical Street Address • Number of Residents • Road Access • Road Surface • Adequate Width • Turnouts, Turnarounds • Bridges • Stream Crossings • Grade

  14. Structure Assessment Checklist • Structure/Building • Single Residence/multi complex/out building • Exterior walls • Large Windows • Fuel tanks • Roof Materials • Eaves

  15. Structural Protection Safety • Be aware of toxic smoke • Full PPE • Conserve water • Keep a reserve in your water tank • Keep protection lines between crew and engine • Back your engine into position • Use 11/2 lines when possible • Do not use long hose lays • Use class A foam if available • Do not park under power lines, next to propane tanks, or in chimneys or saddles

  16. Structural “Watchouts” • Poor Access and narrow one-way Roads • Bridge Load Limits • Wooden Construction (Roofs, Decks, Eaves, Large Windows) • Power lines, Propane Tanks, HazMat Threats • Inadequate water supply • Natural fuels 30’ or closer to structure • Structures in Chimneys, Box Canyons, Narrow canyons or on steep slopes • Extreme fire behavior • Strong Winds • Evacuation of Public • Power lines

  17. Safety Zones • Always look for safety zones and escape routes when positioning apparatus and crew. Here are a few manmade or natural barriers to consider.

  18. Safety Zones • Structures • Outbuildings • Fuel breaks • Rock outcroppings

  19. Apparatus Positioning • When positioning apparatus here are some considerations. • Note landmarks and hazards as you approach scene. • Always back your engine in for rapid egress. There is no exception to this rule. • Park engine so it does not block traffic.

  20. Apparatus Positioning • Avoid parking next to flammable vegetation, under power lines, near LPG tanks, or other potential sources of heat. • Park engine to facilitate structural protection within reach of hose lines. • Survey area for hazards i.e. septic tanks. • Review maps and survey area.

  21. Apparatus Positioning • Identify and communicate escape routes and safety zones. • Monitor fire behavior. • Make sure apparatus windows are rolled up and doors are closed. • Leave apparatus running.

  22. Rules for Hose Deployment • Limit hose to 200’. • Take hose from same side of apparatus. • Do not block egress of operating fire suppression personnel. • Hose lines should not block the street or cross front of apparatus.

  23. Rules for Hose Deployment • Do not hesitate to leave lines in place if position is threatened. • Always have hose line in place to protect apparatus.

  24. Mobility • When moving from location to location do not take the time to reload or to roll hose. Place hose on top of apparatus or over pump panel for easy deployment.

  25. Structure Protection • “Partial Containment”- is a method used to modify or diminish fire as it approaches your assigned area. • To use this method, rear hose lines attack and split the fire from the fire side of the structure. These lines are then moved toward the front of the structure controlling and directing fire at sides of building and to the front.

  26. Structure Protection • “No Containment”- is when fire is permitted to pass by the structure without being challenged. • The objective in this mode is to cool the structure to withstand the heat of the fire as it passes. • This method is extremely dangerous.

  27. Structure Protection • “Full Containment”- is accomplished with use of water and/or hand tools. Typically is due to a lack of fuel.

  28. Retreating • Retreating may become necessary due to fire intensity or equipment/apparatus failure. • In these instances be aware of: • Other companies retreating in low visability environment. • Potential for accidents is high. • Be cautious of hazards created by fire.

  29. Local Resources • Puget Sound Regional Hand Crew • District 10 wildland crew • DNR Fuel moisture content • Strike Teams • http://maps.google.com/
