What is the purpose of activating a TIC during fire investigations?

Activating a TIC, or Thermal Imaging Camera, during fire investigations is primarily used to locate heat sources. These cameras can detect variations in temperature, allowing investigators to visualize areas of heat that may not be readily apparent to the naked eye. This capability is crucial after a fire has occurred, as it aids in identifying the origin and cause of the fire by revealing hot spots that could indicate possible points of ignition or areas where fire has spread.

Additionally, the use of a TIC can also assist in detecting hidden fires within walls, ceilings, or other void spaces, which is essential for ensuring the complete extinguishment of the fire and preventing rekindling. This function of pinpointing heat sources is vital for investigators aiming to provide thorough, accurate assessments of fire incidents.
