Thermal Imaging Cameras
A thermal imaging camera (colloquially known as a TIC) is a type of the thermographic camera used in firefighting. By rendering infrared radiation as visible light, such cameras allow firefighters to see areas of heat through smoke, darkness, or heat-permeable barriers. Thermal imaging cameras are typically handheld, but may be helmet-mounted. They are constructed using heat- and water-resistant housings, and ruggedized to withstand the hazards of fireground operations. [1]
Uses
Thermal Imaging Cameras (TICs) are used for a number of operations:
- Finding heat within walls and structures
- Finding hot spots on wild fire during mop up
- Performing an oriented search within a fire
- Structure fire overhaul
- Finding people trapped in a fire, in a building, and outdoors
Limitations
The biggest limitation of a TIC is that they are not able to look through glass such as windows. The room behind a window may be very hot and in the TIC it may appear as cold or just warm. You cannot search a room for a missing person through an intact window. Additionally, glass and mirrors may show heat that is actually a reflection from elsewhere.
MEFD uses two types of TICs
TICs integrated into our MSA G1 SCBA. Each engine has three airpacks with a TIC. See SCBA
