Firefighting Operations Bulletin 7
“Thermal Imager”
TICs enable firefighters to “see through” smoke-filled rooms by taking advantage of what?
Greater optical depth in infrared region of electromagnetic spectrum compared to the visible region.
Firefighters use TIC’s for the following:
Search and rescue
Locating fires
Locating escape routes
Locating hot spots in salvage and overhauls operations
Haz-Mat incidents
In general, infrared imaging systems are classified into four wavelength regions:
The near infrared spectral range (NIR)
The short wavelength infrared region (SWIR)
The mid-wavelength infrared region (MWIR)
The long wavelength infrared region (LWIR) and it is in this spectral region that firefighting thermal imagers operate.
Firefighting thermal imagers are designed to measure what?
Radiation that is emitted from objects, rather than radiation that is scattered by objects in the scene. Also, thermal imagers are designed to detect radiation emitted from objects corresponding to a particular temperature range.
What are the two important reasons why firefighter thermal imagers utilize the long wavelength infrared region (LWIR):
Sufficient emissions from objects at ambient temperatures.
Minimal loss due to ambient gases and particles. Infrared imagers which are designed for firefighting applications must also provide sufficient contrast so that the firefighters can identify objects (doors, windows, people, fire, etc.) in the image.
If you are looking through the TIC and you see an image that is white what does this mean?
That you are looking at the hottest area in contrast. The cooler areas will be black. Keep in mind though, that the temperature differential may be a few degrees or a few hundred degrees.
Will the TIC return a useable image if everything in the room is the same temperature?
No, neither hot or cold.
On what apparatus are TICs carried?
Truck companies and rescue squads
During exterior operations who should carry the TIC?
The truck officers should consider carrying the TIC themselves as this will allow quicker exchange of information as conditions change.
When should the TIC always be utilized and where should it be positioned?
The TIC should be utilized on all structural fire incidents and, if possible, it should be operated directly behind or in close proximity of the attack line.
When should the TIC be used ahead of the attack team?
Never
The TIC will show the user a:

One-dimensional view
Two-dimensional view
Three-dimensional view
None of the above
B. Two-dimensional view
When using a TIC, which part of the room should be scanned first?
The ceiling area should be scanned first and then the walls and floor.
When operating with the attack line, TIC operators should consider scanning the area ____________, periodically allowing the operator to monitor possible changing conditions in the exit area.

In front of them
Behind them
Beside them
Above them
B. Behind them
Which rescue squad teams should carry the TIC on structural fires?
Both
What is the primary use of the TIC:

Directing the attack line
Rapid Intervention
Salvage and Overhaul
Search and Rescue
D. Search and Rescue
After each use of the camera, the battery should be recharged for a minimum of ___ .
4 hours
A digital read out of the temperature of the object framed by the target area is located in _____________ of the display screen.

Lower right
Lower left
Upper right
Upper left
A. Lower right
The minimum reading of the TIC is:

32 degrees C
32 degrees F
100 degrees F
15 degrees C
B. 32 degrees F
(0 degrees C)
The TIC can be cleaned with:
A dampened cloth with a solution of water and mild detergent.
Parts and service for the TIC are available from:

Facilities Maintenance
On-duty Special Ops. BFC
Fleet Maintenance
On-duty Safety Officer
B. Safety Officer

FIREFIGHTING OPERATION BULLETIN # 7
THERMAL IMAGING CAMERAS
What color are the cooler temperatures?
Blue
What color are the warmer temperatures?
White
As temperatures increase what color will the images be shown in?
Yellow and red
What temperature does high sensitivity mode operate up to?
3000 F
What will the TIC do when temperatures reach above 3000?
The TIC will switch to the low sensitivity mode.
Why does the TIC switch from high sensitivity to low sensitivity mode?
If it didn’t the screen would white out.
What does the operator need to know when operating the camera?
Know what mode the camera is operating in and utilize the temperature read out and or temperature bar on screen to know what the temperature is of the area or object.
What is shuttering?
The TIC’s image may freeze on screen at times. The TIC is refreshing the focal plane in order to operate properly. This function is normal.
In what mode might the TIC do “shuttering” more often?
Low sensitivity mode
What will the TIC not transmit through?
Glass and Water
Where do you never aim the TIC?
At the sun - may cause severe damage to the unit
What is the sensitivity distance of the TIC?
3’ to infinity
During a field test at TA flashover simulator what Temperature range was displayed on the TIC prior to rapid increase of temperature and flashover?
4000 to 4500 The TIC was aimed at the ceiling
How many models of TICs does the department have?
3
