Peeling or bubbling paint is primarily an indicator of a concealed fire. When materials such as wood or drywall are involved in a hidden fire, they can generate heat and gases that cause paint to react. This reaction often results in the paint lifting away from the surface or bubbling up, indicating that there is excessive heat present behind those surfaces, which could signify a fire hidden from immediate view.

Identifying this kind of indicator is crucial for firefighters, as it helps them to recognize areas that may require further inspection or firefighting efforts. It signals the possibility of unseen fire activity that could pose a danger to both personnel and property. Understanding these signs is part of the training firefighters undergo to assess risks and potential hazards effectively while operating in fire scenarios.
