In firefighting terminology, what does the phrase 'hidden fires' refer to?

The phrase 'hidden fires' in firefighting terminology specifically refers to fires that are concealed within structures. These types of fires can be particularly hazardous because they are not immediately visible, making it difficult for firefighters to locate and extinguish them effectively. They may exist within walls, attics, ceilings, or other areas where smoke and flames are not readily apparent but can still pose a significant threat to both building integrity and safety.

Addressing hidden fires requires specialized techniques and training to detect and combat these concealed hazards, often using thermal imaging cameras to locate areas of heat or smoke behind walls, where flames could be present yet undetected. Understanding the nature of hidden fires is crucial for ensuring safety and effective fire suppression in firefighting operations.
