1Salvage, Overhaul, and Fire Cause Determination Chapter 20Salvage, Overhaul, and Fire Cause Determination
2IntroductionSalvage and overhaul operations are not viewed as critical tasks.During the fire attack, firefighters can watch for signs and conditions to assist fire investigator.The chapter explains reasons for and importance of salvage, overhaul, and fire cause determination.
3Salvage Tools, Equipment, and Maintenance Fire incidents have a potential loss of material goods.Scene “triage”Basic premise of salvage operations is to remove harmful atmosphere from material.Use proper tools.Some operations require complex equipment.
9Water Vacuum Two basic types: Backpack cannot be worn with SCBAs. On wheelsBackpack cannot be worn with SCBAs.Used to drain catch-allsLimited capacityAnother option is a pump.
10Miscellaneous Salvage Tools Some other toolsHammerNailsStaple gunsVisqueenDoors and windows securedSalvage covers
11Maintenance of Salvage Tools and Equipment After use, tools must be cleaned and inspected.Tools often exposed to hazardous materialsReimbursementDo not allow debris to spill from salvage cover.Loose fold and roll
13Salvage Cover Folds and Rolls CoversRolledFoldedAvailable compartment space dictates methodTwo firefighters are needed to roll a cover.Fold cover neatly like a bed sheet.
14Salvage Operations Safety considerations Sprinkling heads Protecting material goodsArranging of furnishingsWater removalPost indicator valve and outside screw (stem) and yoke valve
15Salvage Operations (cont.) Sprinkler stopsUse sprinkler stops if no valves can be located.Importance of salvage operationsCan be as important as any actions performed on emergency sceneMake something good out of a bad situation.Preserve as much property as possible.
16Overhaul Tools, Equipment, and Operations Process of overhaulTools used for overhaul built for following tasks:Tearing into buildingCutting through floorsPulling ceilingsSearching for hidden fires
17Common Tools Common overhaul tools: Pike poles Pitchforks Rubbish hooksShovelsAxesChain sawsCarry-allsWheelbarrows
18Carry-All 1.8 metre square (6-foot-square) piece of heavy canvas Rope strung through grommetsUsed to carry debris out of buildingUsed where wheelbarrows cannot be taken
19OperationsAfter fire investigation, overhaul investigations can begin.Hidden fireThermal imaging camerasWooden structural membersInsulation
20Overhauling Roofs Long process Multiple roofs Pitched roof may be built over flat roof.Creates two attic spacesOverhaul nightmare
21Electronic Heat Sensors Relatively new way to check for hotspotsDetermine where heat is higher compared to surrounding areasAlerting mechanisms differSome used to find people
22(A)(B)(A) Helmet with thermal imaging camera attached. (B) Firefighter using a handheld thermal imaging camera.
23Revisits of the Involved Structure Important to revisit sceneWise to make additional checksTwo hours after last company leaves and again within 10 hoursNext shiftFire watch
24Debris Removal Removing debris Loose material Place material in a pile and lightly hose down.Cover debris with Visqueen.
25The Importance of the Overhaul Operations Customer service aspects:Hidden firesLimit amount of uncovered debrisLeave building in a safe stateOverhaul work is often the only thing owners get to see the result of.Make sure overhaul work is in concert with fire investigator.
26Fire Cause Determination Concerns Possible clues as to how the fire startedFirefighters should listen to the reported information.During response, additional information may be gathered by questioning.Firefighters must ensure that investigator pre-approves removal of any part of structure.
27Preservation of Evidence Items that seem out of the ordinaryLeave items where they are found.Protect and preserve area.Cordon off area.Compromised evidence and areasLegal actions
28Basics of Point of Origin Determination Scientific pursuitScientific approachPath of least resistanceFire’s starting pointDepth of charDamage can be influenced by many factors.
31Lessons Learned Salvage and overhaul duties are vital. Salvage and overhaul have a direct impact on success of incident.These duties are a great customer service for the homeowner, even if they are never recognized.
