What is NOT true in regards to thermal imaging devices?

Thermal imaging devices are specifically designed to detect infrared radiation—heat emitted by objects. They are highly effective in searching for heat signatures, which can aid firefighters in locating victims, identifying the seat of a fire, and finding hidden fires. The capabilities of these devices are profound in obscured environments, where visibility is severely limited due to smoke, darkness, or other obstructive factors.

However, they intrinsically have limitations regarding their ability to see through certain materials. For example, thermal imaging cannot penetrate water, glass, or highly reflective surfaces. Such materials impede the sensor's ability to detect heat. Therefore, stating that these devices can see through water, glass, and reflective surfaces is incorrect.

This understanding reinforces the critical operational knowledge needed when utilizing thermal imaging technology in firefighting scenarios. It's essential for firefighters to be aware of these limitations to employ the technology effectively and make informed decisions during rescue operations and firefighting strategies.
