Which factor is NOT considered in identifying smoke behavior?

Identifying smoke behavior is crucial in firefighting as it provides vital information about fire conditions and potential hazards. Sound is not typically a factor considered in analyzing smoke behavior. Instead, firefighters focus on the physical properties of smoke, such as density, color, and movement.

Density refers to how compact the smoke is, which can indicate the intensity of the fire and how it may behave. Color can give clues about what materials are burning; for instance, dark smoke often signifies a material burning incompletely, while white smoke might indicate the presence of water vapor or a cleaner burn. Movement of the smoke helps in understanding ventilation patterns and how the smoke is spreading, which can inform methods of attack and evacuation strategies. Sound, while it might serve as an indicator of fire activity or structural conditions, does not provide direct information about the smoke itself. Thus, it is not a primary factor in assessing smoke behavior during firefighting operations.
