3 Countryside Cameras 4131 Bullard T3 Max 4110 MSA Evolution 5200
4 Camera Features Bullard T3 Max Microbolometer Core EI mode Will ShutterEI modeRelative Heat IndicatorElectronic Thermal ThrottleSuper Red Hot Feature
5 Camera Features MSA Evolution 5000 and 5200 Microbolometer Core Will ShutterOptional quick temp indicator with digital measurementLow sensitivity mode indicatorShutter indicatorHeat seeker plus indicatorOver temperature indicator
6 Bullard T3, MSA 5000 & 5200 ShutterThe unit has an automated shutter used to calibrate or change sensitivityFires about every seconds depending on environmentWhen it fires screen will freeze for 1-2 seconds
7 Bullard T3 Max EI mode 2 levels of operation Normal- low temp scenes EI –elevated temperaturesAutomatically switch when object viewed >300 degree FWill shutter between modes
8 Low Sensitivity Mode Indicator MSA Evolution 5000 and 5200Low Sensitivity Mode IndicatorWill automatically switch when TIC senses environment about 300 degrees F“L” appears on lower right corner of screen
9 Relative Heat Indicator Bullard T3 MaxRelative Heat IndicatorBar graph on right side of screenTemp accuracy decreases as distant from object increasesAccuracy of indicator dependent on;Distance from objectEmissivity (ability to radiate heat)
10 Optional quick temp indicator with digital measurement MSA Evolution 5000 and 5200Optional quick temp indicator with digital measurementSimilar to relative heat indicatorTemperatures from 32 degrees F to 300 degrees in high sensitivity mode and 32 degrees to 1000 degrees in low sensitivity modeDigital value only displays approximate value
11 Relative Heat Indicator Bullard T3 MaxRelative Heat Indicator
12 Bullard T3 Max Thermal Throttle Enables firefighters to optimize the scene with the touch of a buttonPinpointing hot spots during overhaul, searching for overheated electrical equipment, and distinguishing hotter objects from cooler onesPaints the hottest objects in the scene blue, leaving other hot objects white
14 Bullard T3 Max Thermal Throttle For firefighter safety, the ETT blue feature does not operate when the T3 MAX detects it should be operating the Super Red Hot feature
15 Bullard T3 Max Super Red Hot Feature Heat levels are identified by colorStarting at 500 degrees, heated objects are yellow transitioning to orange then redProvides enhanced visual awareness
16 Optional Heat Seeker PLUS Indicator MSA Evolution 5000 and 5200Optional Heat Seeker PLUS IndicatorGraduated color (yellow to orange to red) of portions of a scheme that are above 275°F(135°C)-yellow, 297°F-red, in High Sensitivity, or 842°F-yellow, 914°F-red, in Low Sensitivity mode
17 Over Temperature Warning MSA Evolution 5000 and 5200Over Temperature WarningLower left below screenFlashing red indicates exceeded recommended operational thermal limitsTests on the Evolution TIC’s indicate that it will provide an acceptable image when subjected to an ambient temperature or approx. 248 degrees for about ten minutes. Exposure to conditions exceeding these will result in deterioration and loss of image.
18 Emitters Active Passive Direct Produce own heat Human Object that can be heated or cooledDoes not produce own heatDirectSource of heatSun, fire
21 What a TIC will doAllows you to “see” the area that you are working in.Dramatically cuts down the time for a primary search.Narrows down the search area.Locate the seat of the fire quicker.Assist with size-up.
22 What a TIC Won’t Do Won’t “see” through water, windows or windshields. Infrared wavelengths won’t pass through those types of mediums.
23 What a TIC Won’t Do Won’t “see” through furniture. Won’t “see” through walls, floors, etc.It will “see” heat transferred through walls.
29 RIT SCBA bottles and fittings will appear dark Reflective trim on gear will contrast with fire resistive materialFirefighters will not be located in the traditional locations that civilian victims are foundLook for signs of firefighter presence (marked thermal layers, hose lines,cold/wet spots, etc.)
30 RITSCBA bottles and fittings will appear dark while straps and padding will absorb heat
31 RIT“Reflective trim on gear will contrast with fire resistive material”
32 Electrical Outlets Obtain Thermal Image Identify problem outlet Use traditional means to check for heatObtain Thermal ImageIdentify problem outlet
33 Electrical Outlets Or if you see this starting to occur Monitor area and ensure thermal outline decreasesDecreases causing unnecessary damageWhen is it time to open up??Anytime you want to..Or if you see this starting to occur
35 SEARCHING W/ TICInterior searches should be approached with safety in mind.Do not abandon current safety practicesTeamsPatternsOrganizationCommunicationsUSE OTHER SENSES AS WELLStay lowREALITY CHECKSTake non-camera views- every 30 seconds
36 Six-sided Approach First (UP) Second (DOWN) THIRD, FOURTH , FIFTH Ceiling where heat is, heated gasses, extension or collapse areas. Where is it moving?Second (DOWN)Floor. No holes, make sure you are not directly over the fire or other hazards.THIRD, FOURTH , FIFTHRight, Center, LeftLook for hazards, egressSIXTH (BEHIND)Hazards, changing conditionsEgress routes
38 SEARCHES w/ TIC Camera Directed Search TIC operator makes a room Gets 6 sided view“DIRECTS” search crews through spaceStays at the door or egress point for when camera malfunctions
39 SEARCHES w/ TIC Camera Led Search TIC operator makes a room Gets 6 sided viewCamera operator with the TIC searches the spaceUnsighted crews stay at the door or egress point for when camera malfunctions
40 SEARCHES w/ TIC Point to Point Accelerates searches Does not search areas he/she can see are clearWhen in doubt, searchUtilized in conjunction with other search techniques
41 SEARCHES w/ TIC TIPS Review where you have been Check for changing conditionsCommunicate often and clearlyEstablish landmarks, window sill tops, door jambs to evaluate thermal layer -Make one if necessaryDO NOT forget the basic fundamentals of proper searchingReality checks oftenScan shoulder to shoulderLet a searcher see the area prior to searching
42 SEARCHES w/ TIC TIPS TICS can fail TICS WILL FAIL Cannot see through water, glassDepth perception is alteredNOT intrinsically safeGlass or smooth surfaces will reflect an imageScan horizontal not vertical
43 Ventilation Use TIC to find ventilation points Vent over seat of fire See” the truss systemCut-man can see the area in need of cutting
44 OverhaulUse thermal throttleOverhaul hottest areas
46 TACTICAL CONSIDERATIONS Three main things we are looking forLife SafetyOccupants, down fire fightersFire ConditionsThermal LayeringConvected heat and fire gassesFire sourceStructural ConditionsStructural integrity
50 Common Mistakes Made Neglecting the physical search Relying SOLEY on the cameraTIC operator strays from rest of crewCrews forget basicsLeave walls, hose linesCommunicationStanding up in thermal layerCrews now WALK, or worse, RUN through buildings
51 Common Mistakes Made Crews miss exits Manpower limitations Not clearing condensation off of lens and germaniumForgetting that the TI has no peripheral visionMissed holes in floorsWater on floor will look like a hole
