What is the purpose of a thermal imaging camera in firefighting?

The purpose of a thermal imaging camera in firefighting is to locate victims and check for fire extension. These cameras detect infrared radiation, allowing firefighters to see heat signatures even in smoky or dark environments. This capability is crucial for identifying individuals who may be trapped and for assessing the spread of fire through walls or ceilings that may not be visibly burning but are hot enough to indicate fire extension.

By using thermal imaging cameras, firefighters can quickly map out the scene, locate hot spots that require attention, and ensure that no victims are missed during a search. This technology enhances safety for both the rescue personnel and the individuals in distress, making it a vital tool during firefighting operations. The other options, which pertain to measuring humidity, detecting oxygen levels, or monitoring air pressure, do not directly relate to the primary function of thermal imaging in firefighting scenarios.
