Conventional firefighting methods typically rely on large volumes of water. While water is effective for surface-level fires, it is far less effective when fire activity originates deep within materials or structures. In such cases, extreme internal temperatures can cause rapid evaporation, preventing sufficient heat absorption and allowing fires to persist or re-ignite after apparent extinguishment.
These fire scenarios are especially difficult to control because the primary hazard is internal rather than visible. Combustible materials such as plastics, oils, and organic matter can interact under high temperatures, creating sustained thermal reactions. Internal temperatures exceeding 600°C are not uncommon, making it challenging to achieve lasting fire suppression through conventional cooling alone.
