Which smoke color indicates a hotter intensity fire?

The presence of black smoke during a fire indicates a hotter intensity fire due to the combustion of materials in a way that produces a significant amount of unburned carbon. This typically occurs when the fire is fueled by synthetic materials, such as plastics or oil-based products, which release more energy when burned compared to organic materials. A hotter fire will create thicker, darker smoke as more fuel is being consumed, and the incomplete combustion leads to carbon particles that result in black smoke.

Additionally, black smoke can often be an indicator of a rapidly developing fire, which can pose greater dangers for firefighters and necessitates immediate action and precaution. Understanding the implications of smoke color is crucial for effective firefighting strategy and safety protocols during a live fire scenario.
