Using HVAC for smoke control can affect which aspect of firefighting?

The main idea here is that smoke control through the building’s HVAC system directly changes how air moves inside a fire building, which is exactly what tactical ventilation relies on. When you use HVAC to shape smoke movement, you’re altering pressure zones and draft directions, so the planned ventilation path can either help clear smoke and heat or conflict with it and push smoke into unintended areas. That makes HVAC-based smoke control a factor that most directly influences how you perform tactical ventilation, including when and where to create openings and how crews will move and operate safely. It doesn’t change how much fuel is burning or the building’s structural integrity, even though those aspects remain important considerations.
