Where firefighters come to talk training

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 think? Pictures and video of either side are welcome as well.

-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.
