What is the term for the movement of heat and smoke from an area of higher pressure to lower pressure?

The movement of heat and smoke from an area of higher pressure to lower pressure is referred to as a flow path. This term encompasses the dynamics of airflow in fire scenarios, illustrating how gases—including smoke and heat—navigate through a structure as a result of differences in pressure.

Understanding the concept of flow paths is crucial for effective fire suppression tactics, as it helps firefighters predict and manage the spread of smoke and heat. Incorporating knowledge about flow paths allows responders to execute strategies that can minimize exposure to hazardous conditions and improve ventilation tactics, ultimately enhancing safety and efficiency in firefighting operations.

The other options, while related to fire dynamics, do not specifically denote this critical movement of gases as effectively as the term flow path does.
