FETC,

Thanks for the comments, they're always appreciated.

Regarding the view, the videographer was sitting in the same position for both videos. The biggest difference was that the first Nozzle FF brought the line into the room (getting out the doorway/ chimney), while the second stayed in the doorway.

The visibility at the end of the first attack clip is how it stayed. The "blackout" at the end of the second was from the steam (no video editing or effects). The same nozzle was used for both attacks with very different results.

As a trainer, do you find that firefighters seem to only be trained at the certification level (i.e. this is a hose, this is a nozzles, wet goes on red)? There are a tremendous amount of nuances to our profession, little things that make a huge difference.

Thanks again for the comments. By the way, do you mind if I copy your comments to my site www.safefirefighter.com?

Matt, the video depicts the difference between a properly used combination nozzle verse not, in a non-ventilated room and contents fire. The state in which the occupancy is, also depicts whether the application is correct or not.

The first evolution the firefighter is using a combo nozzle in the "Right to Fight" application mode. We run these on our engines and they will flow 200gpm at 75 tip pressure. The video demonstartes similiar characteristics of a smooth bore nozzle. The second evolution is a firefighter who opens the bale in the "Left for Life" mode, and decides to wash the super heated floor for a while. That improper and incorrect method alone would create un-wanted steam conversion.

I would have liked to see the same camera angle to compare the decreased vision, and thermal layer disruption.
