"-Will, I agree that the tactic does in fact work but vertical venting must meet some very specific parameters. I would invite you to read my July 24 post above."

Michael Bricault replied to Chris Leier's discussion Vertical Ventilation in the group Truck Company Operations"-Jacob, as a matter of technical correctness the 4x8 foot ventilation h*** is not a trench cut, its just a big vent h*** measuring 4x8 feet. This is not minutia; rather it is a technical point of fact and in order to better understand the mission…"
Jacob Smith replied to Chris Leier's discussion Vertical Ventilation in the group Truck Company Operations"yes vertical ventilation does work. At my department we don't vent all that much or see that much fire for that matter. but we do train on it all the time. We have deen going away from the recuit school method of doing a 4 x 4 cut and started…"
Brandon Krause replied to Chris Leier's discussion Vertical Ventilation in the group Truck Company Operations"As far as does it work, yes it does! As Michael said you have to meet certian requirements though. When dealing with opening size, I teach to open up an area equivalant to approx. 10% of the roof size. This may require multiple openings which are…"
Shareef Abdu Nur replied to Chris Leier's discussion Vertical Ventilation in the group Truck Company Operations"yes, vertical ventilation does work. 4x4 holes can change conditions for the interior members quickly. not all situations call for vertical ventilation. many situations demand horizontal ventilation, but this is where good size up comes into play."
Eric Myers replied to Chris Leier's discussion Vertical Ventilation in the group Truck Company Operations"Chris-
I have noticed the 4 x 4 h*** go by the wayside. The amount of BTU's being generated with synthetics just doesn't allow for the traditional size cut. You have to assess the amount of fire and smoke being produced from the h***. Is…"

I agree with your points.

Michael Bricault replied to Chris Leier's discussion Vertical Ventilation in the group Truck Company Operations"-Esteban, this is indeed an interesting video though I'm not sure where the video was shot. It is most certainly not the city of Boston, Massachusetts.

Boston Fire I think..
Vertical ventilation does work, if this really needed. If don't, you waste time and threat the firefighter with roof collapse.
For other hand, look the windows on…"
Michael Bricault replied to Chris Leier's discussion Vertical Ventilation in the group Truck Company Operations"-The technique does in fact work. That being said, there are some very specific parameters that must be meet in order for vertical venting to work properly.
-First and foremost is that the truck company must be on the roof and completing the vent…"
Matt Thomson replied to Chris Leier's discussion Vertical Ventilation in the group Truck Company Operations"Chris, yeah it works. A lot of departments got away from vertical ventilation for various reasons but most departments that still do it know the benefits. There is a good video on you tube that illustrates the effectiveness of vertical ventilation.…"

Vertical Ventilation
My question to everyone here is, what is your opinion on vertical ventilation? For years and years we preach that venting the roof is a way to let the hot gases escape to prevent flash over and improve conditions inside. Does this really work? Or does the fire produce so much hot gas, that a 4' by 4' h*** in the roof really has a negligent effect on the overall anticipated outcome. It is a question that I hope to one day supply the technical data to support or discount, but what does everyone…See More
Chris Leier posted a discussionHow your company handles their turnover process...
This is mostly for the volunteer/combine departments, but any input is welcome. At my station here in College Park, MD the process of becoming an interior firemen is very intense as you have to have FF1, EMT-B, and go through our station in house training. The in house training is very demanding and is pretty much equivalent to FF1 and FF2 according to how we do things at our station. This process usually takes about 3 months over the summer, training every night. I am just looking to see what…See More

Training is something that is imperative to success as a firemen and is taken very seriously here. What do you guys do? Or is it just FF1 and you are good to go?
Stay safe, Chris
