Tic

Front 1

How does the TIC work?

Back 1

-Detects and translates infrared energy into visible light.

-Detects differences in relative surface temperatures.

Front 2

What are the 3 categories of infrared emitters?

Back 2

-(1) Passive emitters: inanimate objects; these objects primarily absorb and dissipate energy from active or direct emitters; generate no heat of their own (tools).

-(2) Active emitters: living organisms; give off infrared energy in low to medium strength and in varying intervals (victims).
- (3) Direct emitters: energy sources; give off constant high strength infrared energy (fire).

Front 3

Thermal image interpretation?

Back 3

-Black = absence of heat

-White = presence of heat (relative to the environment)

-Gray = something in between

Front 4

When does thermal inversion occur?

Back 4

-Occurs when the environment affects the shade of an object (image changes from light to dark or dark to light).

-Occurs when the ambient temp around an object rises above the temp of the object (ex: person in a hot room goes into a cold room).

Front 5

How is thermal balance maintained?

Back 5

Maintained with effective ventilation.

Front 6

What is the 6-Point Scanning Technique?

Back 6

-Shoulder to shoulder @ ceiling level.

-Shoulder to shoulder @ mid-level.

-Shoulder to Shoulder @ floor level.

Front 7

What are scanning priorities?

Back 7

-Heat sources (look for flames, hot spots, hot wires, etc.)

-Exits (look for a way out – look for contrast and shape)

-Victims (look for contrast and shape)

Front 8

What does the thermal throttle do?

Back 8

-Allows firefighters to pinpoint the hottest objects at a scene by coloring them blue.

-NOTE: Only available on newer cameras.
