1 BULLARD T4MAX THERMAL IMAGER CAMERA

2 OBJECTIVES IDENTIFY ALL COMPONENTS & FEATURES OF BULLARD T4MAX DEMONSTRATE USES AND APPLICATIONS DISCUSS CARE AND MAINTENANCE DISCUSS OPERATIONAL CAPABILITIES & LIMITATIONS

3 T4MAX APPLICATIONS FIRE ATTCK SEARCH AND RESCUE RAPID INTERVENTION OVERHAUL WILDLAND (Locate Hot Spots) ROOF OPERATIONS (Structural Member Identification, Fire Below) USAR & HAZ MAT INCIDENTS

4 T4MAX ACCESSORIES HANDLE COMBINATION STRAP

5 NiMH BATTERIES CHARGER Place pic here 12O VOLT ADAPTER NiMH BATTERY 12 VOLT ADAPTER

6 CLAMSHELL

7 BATTERIES The T4MAX comes with 2 NiMH batteries and 1 clamshell. Fully charged NiMH batteries should have a run time of 3 hours. Batteries cannot be overcharged in the charger. The charger will initiate a trickle charge after fully charging. Manufacturer and the Department recommends cycling the battery monthly. This can be accomplished by turning on the TI and allowing the battery to run down until the ORANGE LED status bar is displayed. Then fully recharge. Doing so will extend battery life. NEVER ALLOW THE BATTERY TO RUN DOWN COMPLETELY. DOING SO WILL DAMAGE BATTERY CELLS SO THEY NO LONGER HOLD A FULL CHARGE.

8 BATTERIES Clamshells utilize 8-AA alkaline batteries Keep fresh AA batteries in TI case for the clamshell Once the NiMH battery life reduces to 30 minutes Obtain replacement battery Replacement batteries can be requested through the Equipment Maintenance Shop located at Pacoima ( )

10 CARE INSTRUCTIONS Clean the outside of the unit with mild soap or detergent. Wipe the lens with a soft cloth. Do not use solvents or paint thinner. This may permanently damage the protective properties of the casing. Do not intentionally submerge the unit underwater or subject to high pressure water.

11 REPAIRS TI units needing repair shall be sent to the Equipment Maintenance Shop at Pacoima ( ) A loaner TI will be issued

12 POWER/ZOOM POWER ZOOM

13 DIGITAL ZOOM ACTIVATE THE DIGITAL ZOOM BY PRESSING THE BLACK BUTTON NEXT TO THE POWER BUTTON. FEATURES A 2X AND 4X DIGITAL ZOOM. WILL WORK WITH THE THERMAL THROTTLE.

14 THERMAL THROTTLE THE THERMAL THROTTLE IS A TOOL TO HELP FIREFIGHTERS DETERMINE THE HOTTEST OBJECTS IN THE SCREEN. USEFUL WHEN THERE IS SLIGHT TEMPERATURE DIFFERENCES OF MATERIALS ON THE SCREEN. ENGAGING THE THERMAL THROTTLE TRANSFORMS THE HOTTEST OBJECTS ON SCREEN TO BLUE. CONTINUING TO HOLD THE DOWN BUTTON WILL EVENTUALLY TURN ALL OBJECTS ON THE SCREEN BLUE.

15 THERMAL THROTTLE POSSIBLE USES FOR THE THERMAL THROTTLE FEATURE IDEAL FOR PINPOINTING HOTSPOTS SEARCHING FOR OVERHEATED MECHANICAL EQUIPMENT CLARIFYING OBJECTS IN AMBIENT LIGHT SITUATIONS USEFUL IN FINDING VICTIMS IN WILDERNESS SEARCH OPERATIONS

16 THERMAL THROTTLE OPERATING THE THERMAL THROTTLE FEATURE ACTIVATE BY PRESSING THE DOWN BUTTON. SYMBOL TT AND A NUMBER BETWEEN RANGE IS DISPLAYED ON THE SCREEN. See video in the Blackboard lesson for further information

17 THERMAL THROTTLE OPERATING THE THERMAL THROTTLE FEATURE ONCE ENGAGED, THE HOTTEST OBJECTS WILL APPEAR BLUE ON THE DISPLAY. TO ENGAGE MORE OF THE SCENE, PRESS THE DOWN BUTTON. THIS WILL LOWER THE TEMPERATURE THRESHOLD AND COLOR MORE OF THE SCENE BLUE. See video in the Blackboard lesson for further information

18 THERMAL THROTTLE OPERATING THE THERMAL THROTTLE FEATURE AS THE THROTTLE ENGAGES MORE OF THE SCENE, THE BLUE WILL BECOME LIGHTER TO DIFFERENTIATE OBJECTS IN THE SCENE. TO DEACTIVATE THE THERMAL THROTTLE, DEPRESS BOTH THE UP & DOWN BUTTONS SIMULTANEOUSLY FOR 1 SECOND. See video in the Blackboard lesson for further information

19 THERMAL THROTTLE THROTTLE DOWN UP

20 THERMAL THROTTLE

21 THERMAL THROTTLE Example image of Thermal Throttle activation. The TT in the lower right hand corner indicates the that the Thermal Throttle is engaged.

22 SUPER RED HOT FEATURE ADD PICTURE OF SUPER RED HOT

23 SUPER RED HOT FEATURE Starting at 500 degrees, heated objects are tinted Yellow and gradually transition to Orange and then Red as the temperature rises. The Super Red Hot feature identifies specific heat layers, alerting firefighters to areas of intense heat. Provides an enhanced visual awareness of the hottest objects in the scene. The Super Red Hot feature is an excellent tool for recognizing rollover and potential flashover.

24 INFRARED PRINCIPLES Infrared Radiation can be : Emitted Absorbed Emitted Again Reflected

25 INFRARED PRINCIPLES Glass IR will not penetrate glass, however heated glass will show up lighter in color

26 INFRARED PRINCIPLES Water IR will not penetrate water, some penetration may occur in a fog or mist Steam IR may or may not penetrate steam depending on it s density

27 INFRARED PRINCIPLES Reflections Infrared Radiation can be reflected by a number of surfaces These can include : Glass, Water, Mirrors, and Shiny Surfaces Reflection

28 IMAGE DISPLAY Hottest Objects : White or Light Shades Coolest Objects : Black or Darker Shades Display is relative to the area viewed

29 IMAGE DISPLAY Temperature listed in the upper right hand corner is the temperature at the cross hair in the middle of the display.

30 IMAGE INTERPRETATION Thermal Contrast how well objects stand out from one another, related to detector sensitivity and the variance of temperature in objects being viewed Low Contrast Background is faded together, victim is all the same shade

31 IMAGE INTERPRETATION Thermal Saturation Not the same as White Out Occurs when objects absorb as much energy as possible and radiate the energy back creating an even temperature and an almost completely white image An All White image can occur during or after a fire

32 IMAGE INTERPRETATION Various examples of TIC used to identify structural members.

33 SCENE ASSESSMENT 1. Regain vision in total darkness, fog, smoke 2. Gain information unavailable to the naked eye

34 HAZARD IDENTIFICATION 1. Identify heat, fire, and ignition sources 2. Evaluate presence of hazardous materials 3. Determine extent of mechanical or electrical hazards

35 VICTIM IDENTFICATION 1. Regain vision in total darkness, fog, smoke 2. Gain information unavailable to the naked eye

36 OPERATIONAL CONSIDERATIONS What is our first priority on all structure fires?

37 OPERATIONAL CONSIDERATIONS 2.Incident Stabilization 3.Property Conservation

38 OPERATIONAL CONSIDERATIONS To stay consistent with the strategic priorities, always bring the TIC in with initial attack.

39 OPERATIONAL CONSIDERATIONS What are your SOP s for getting the TIC to the door?

40 OPERATIONAL CONSIDERATIONS Is the Quint/Truck Inside Firefighter responsible for getting the TIC to the door? If not who is? What is your SOP for using the Battalion Chief s TIC during initial attack? Should you request a TIC to the front door during your radio report?

41 OPERATIONAL CONSIDERATIONS Assuring the TIC is used during initial attack The Captain can request the TIC while enroute or immediately upon arrival. For BC s co-located with first alarm units, hand off the TIC prior to responding. If the squad is assigned Search & Rescue, they should make every effort to get a TIC prior to entry.

42 OPERATIONAL CONSIDERATIONS Constantly evaluate surrounding conditions Do not get tunnel vision with the thermal imager During thermal imager operations..always BRING A SPARE BATTERY Momentary image freezes during use are common and due to self-recalibration

43 FIREFIGHTER SAFETY Firefighter Safety Remember! You have to look at it You have to interpret it The imager can not do it for you!

44 HANDS ON DRILL Now get your HANDS ON the TIC and apply what you ve learned.

45 1. IN A LOW TO ZERO VISIBILITY ENVIRONMENT, COMPLETE A SEARCH OPERATION TO FIND A DOWNED FIREFIGHTER. 2. IN A LOW LIGHT ENVIRONMENT, UTILIZE THE THERMAL THROTTLE TO IDENTIFY PERSONNEL AT 20'-30' DISTANCES AT MOST EFFECTIVE SETTING. 3. OBTAIN HEAT SIGNATURES AROUND VARIOUS PLACES OF FIRE STATION. 4. CHANGE BATTERY WITH GLOVED HAND.

46 THANK YOU Rio Hondo Fire Academy for the use of equipment and training references LACoFD Fire Behavior Cadre for the hospitality with the live burns
