WUI size-up factors-3
wildland fire behavior, comp/cond of structure, area surrounding structure (defensible space)
What part of a structure is most vulnerable to fire spread?
roof- wood shingle most likely to ignite
structural features that can trap heat and embers: 3
overhanging decks, open gables, eaves
openings were fire brands can enter include: 3
gable vents, crawl space, under decks
What on the exposed side can make fire protection more difficult?
number and size of windows

30 ft from structure to flammable brush/trees
Proper ____ and removal of what three things has been noted to save many homes in the WUI?
pre-treatment
yard accumulation, fences, patio furniture
what are the 4 WUI triage levels in the IRPG?
Defensible Stand-Alone: determining factor: Safety Zone present. Few tactical challenges, not likely to ignite during initial fire front. FF’s may not need to be directly assigned. Patrol after.
Defensible Prep and Hold (tight): determining factor- Safety Zone present. Some tactical challenges. FF stay onsite during fire front.
Non-Defensible Prep and Leave: determining factor- NO safety zone Some tactical challenges. FF not able to stay. Rapid Mitigation Measures may be performed. Set trigger point for safe retreat. Patrol after.
Non-Defensible Rescue Drive-By: determining factor- NO Safety Zone. Significant tactical challenges. FF not able to stay. Ensure people not in structure. Patrol after.
In what WUI Triage level are FF’s needed onsite during fire front contact?
Defensible- Prep and Hold (tight)
To what triage level should a structure in the WUI be assigned if there is no safety zone present and the structure has significant tactical challenges?
Non-Defensible- Rescue Drive-By
In which WUI triage levels is it necessary to set a trigger point for safe retreat?
Both Non-Defensibles: Prep and Leave & Rescue Drive-By
