| Description |
The NIST analysis of 160 experiments conducted with small and large fans in the stairwell of a vacant 30-story building in Toledo, Ohio, showed that the positive pressure ventilation (PPV) techniques used in small homes also worked in tall structures. The NIST engineers found that portable PPV fans, if used correctly, can both limit the amount of smoke and heat entering the stairway, and push smoke and deadly gases out of the structure.
