Here is another video from our Greensboro Flow Path Management Training Experience course.
2-story 5 Bedroom residence w/single bedroom fire on 2nd floor Div.C
Adjacent bedroom doors down the hallway initentionally left opened.
Fireifghter asccends a 35′ ground ladder, breaches Div. C 2nd floor bedroom window next to fire room. Fire Attack/Safety crew with hoseline standing by at top of stairs.
Firefighter enters, conducts a Go..No..Go..thermal and structural assessment prior to entering. While entering, the flow path is redirected to the new opening as depicted in this video indicated by the halway and fire room TIC’s showing fire gases traveling towards search room while the fire growth increases.
Once the window to the search room is breached the flow path changes to a Uni-directional flow path. The is indicated by rapid fire growth and extreme temperatures seen issuing from fire room.
Once the hallway door is closed to the search room, the fire gases in the 1200 degree range can be seen banking down to floor level in the hallway. While the fire begins to burn less efficiently when entering back into the bi-directional flow path.
1. VEIS must be supported with TIC technology.
2. A Second firefighter on the ladder should have the TIC calling out tempratures to the searching firefighter. It was too much for the searching fireifghter to handle using the TIC, probing floors, searching room. The searching firefighter was not keeping up with temperature changes while the search was underway.
3. Rapid fire progression must be anticipated whenever window failures occure either by destruction or fire dept. intervention.
4. Audible and visual cues will indicate changes in flow path and fire growth. When you hear glass breaking anticipate rapid fire progression. Pay attention to how many windows or dorways are open, control them to limited the available air to support fire growth.
