The Need to See QUESTION: What is the biggest challenge facing firefighters today? ANSWER The ability to see.

3

Benefits of Thermal Imaging • Saving lives

4

Benefits of Thermal Imaging • Reduces risk to the firefighter by increasing visibility. – See openings in floor. – Don’t walk into walls.

• Reduces property damage. – Fight fire more quickly, knowing the seat and extension of the fire.

• Determine resource needs more quickly. • Finds residual hot spots – overhaul.

5

Benefits of Thermal Imaging • Increased firefighter efficiency. – Effective placement of suppression materials. – Reduced apprehension.

6

Applications and Use • Accident and incident investigation – Origin of fire. – Skidmarks. – Travel of victims.

7

Applications and Use • Structural fire fighting

8

Applications and Use • Basic structural fire fighting

9

Applications and Use • Ventilation

10

Benefits of Thermal Imaging • Size-up – Efficient location of the seat and extension of a fire.

11

The Need to See • What is thermal imaging? – The ability to see! – Images (pictures) from heat, or infrared (IR) radiation. • All objects give off IR radiation.

21

Thermal Imaging Development • Thermal imaging developed for military applications in 1960’s: – Aerial surveillance. – Weapon sights. – Navy shipboard fire fighting. • Fire service products are generally derived from declassified sensor technologies

22

What a Thermal Imaging Camera Sees • Thermal ‘signatures’ determined Emission

Reflection

Absorption

23

What a Thermal Imaging Camera Sees • Visible Light

Smoke Particles

– Wavelengths (0.1-1.0 micron) are too short to pass through smoke.

• IR – Wavelengths are much longer and pass through smoke and are captured by a TIC!

24

What a Thermal Imaging Camera Sees • Glass is opaque to IR radiation, so a TIC cannot “see” through glass. • While heat conducts through solids and radiates IR energy,a TIC cannot “see” through walls. •

Thermal Imaging is NOT night vision. – Night vision merely amplifies available light!

25

What a Thermal Imaging Camera Sees • What makes a clear, sharp picture? – Lens • F-stop

– Focal Plane Array (FPA) • Array size (320 x 240)

26

What a Thermal Imaging Camera Sees • What makes a clear, sharp picture? – Video Enhancement Electronics – Display • Resolution & Definition
