Systematic from the doorway.
Identify obstructions requiriung further searching
Floors, 4 side walls, ceiling
3 Steps
Life, surroundings, fire?????
The 3 spot wipe involves:
Wiping the exterior of the BA mask visor
Wiping the TIC screen
Wiping the TIC lens
FLIR K65 has 5 operating modes
**TI Basic NFPA mode **
− Yellow starts at 150 °C
− Orange starts at 300 °C
− Red starts at 450 °C
− Dark red (saturated value) > 650 °C
Black and White Firefighting mode.
- This mode is designed for fire services that do not want to use the heat colourisation feature
TI Basic Plus NFPA mode
- Crosshair temerature gauge
Search and Rescue mode
- Yellow starts at 100 °C
− Orange starts at 125 °C
− Dark red (saturated value) > 150 °C
Heat detection mode
- search for people in
water and open landscapes. - Hottest object only is red

There are three (3) categories of
infrared emitters
Passive : Absorbs heast from another source. Hand or heater on an object
Active: Generat own heat. Humans and animals
Direct: Generate heat in large amounts. Fire/heater
Thermal Current
The thermal current is the movement of the thermal layer.
Using the TIC, the layer is visible in shades of grey.
Viewing of the thermal current assists in identifying the:
◼ Direction of the fire – (current moving away from the source).
◼ Intensity of the fire – (current speed).
◼ Volatility of the fire – (current surges/‘storm clouds’ leading to flashover)
Transfer of energy/heat
Convection – occurs via gases. An energy
source will heat the gases, aiding in the
transfer of the energy on air currents. Ducted heater
Conduction – occurs in solids or liquids.
When a heat source is in direct contact with
a material it transfers energy directly
through the material. Fire on metal
Radiation – energy is emitted in the form of
electromagnetic waves which travel through the air and transfers the energy to objects they strike
How does thermal imaging work??????
Thermal imaging improves the visibility of objects in low or zero visibility environments by detecting the object’s infrared radiation and creating an image.
