From NBC5:

"The CFD set fire to the third floor in a process they call Positive Pressure Ventilation, which is conducted by putting huge fans in the base of the stairwell.

The test marked the end of a two weeklong evaluation to determine just how effective this PPV technology to clear stairwells of smoke can be.

"We're looking to create a greater pressure in the stairwell that we designate for evacuation and firefighting and what the fire itself is creating, so we can keep that stairwell clean," said Fire Commissioner Ray Orozco. "We're studying the phenomenon of wind-driven fires that have killed many civilians and firefighters, taking what firefighters have passed down as experience thru the years and creating a manual. This experiment will save lives."
