Evaluation of Ventilation-Controlled Fires in L-Shaped Training Props

Presented by Joseph Willi, Research Engineer III, UL Firefighter Safety Research Institute (FSRI)

Recent fireground line of duty deaths have highlighted the importance for firefighters to understand ventilation-limited fire dynamics. This need is reflected in the 2013 edition of NFPA 1403: Standard on Live-Fire Training, which includes guidelines for conducting ventilation-limited fire training. This presentation examines the ability of three different fuel loads to produce ventilation-controlled fire conditions within various types of L-shaped training props. Two fuel packages contained wood-based materials to be compliant with NFPA 1403, and the third was composed of modern furnishings.

Experiments were conducted to compare the thermal environments created by fires in L-shaped props with three different wall lining configurations: one that resembled modern residential construction and two fabricated from metal shipping containers with corrugated steel walls. Repeatable ventilation-limited conditions were produced by all three fuel packages in each prop. Furthermore, heat flux and temperature measurements at potential locations of trainees exceeded exposure limits of firefighter PPE during a number of the experiments. Finally, differences between thermal environments generated within the various props, including during scenarios involving interior suppression, will be discussed.
