Supported with a DHS/FEMA Assistance to Firefighters Grant, ISFSI and UL FSRI conducted this research to better understand why basement fires present such a high risk to firefighters and what they can do to avoid injury.

This study went beyond earlier research by increasing the size of the basement and incorporating three different ventilation and access conditions to the basement. 

Those access conditions include no exterior access to the basement, limited exterior access to the basement, and exterior access to the basement. 

The results of the experiments show the importance of identifying a basement fire, controlling ventilation, and flowing an effective hose stream into the basement from a position of advantage, as soon as possible.
