Firefighting - Transitional attack - How, when and why?

In this presentation I explain how a transitional attack should be done, with practical tips for firefighters. In the end I give my views on how it fit into firefighting as a whole and the combination with interior attacks.
This presentation was made for fire officers in the eastern part of Europe in 2023.
Want to use my content in training?
I produce firefighting videos with explanatory graphics and potentially me as a speaker.
Up until now I have only done so in Swedish due to time restrictions and fear. I think it is highly scary to tell you what I think.
But I would like to start to do this in English, so if you are interested please let me know!

I enjoyed this video, it was well produced and easy to follow. I will share it with my crew and other company officers and create some discussions. Thank you for making it.

Very very good arguments and demonstrations. I am very thankful for your time and effort. I am, however, now😊 questioning everything I know and have done lol 😆 😅

[@swedishfirenerd]

Well, at worst you justify what you are already doing. At best you re calibrate and improve. Either way I am glad I provided some value 🙂

Thank you for a good vid😊👨‍🚒🚒 Are you an instruktor at Sandö or Revinge, or are you an instruktor at a firedepartment?

[@swedishfirenerd]

Neither. I have my own training company doing training for individuals, departments or other companies.

One of the best presentations you have given.
One question, how noticeable is the negative zone at 09:03? great job!!!

[@swedishfirenerd]

You mean the average in the entire room while doing the transitional attack? In that case none, there is probably an over pressure in the room.
If you mean locally behind and beside the stream hitting the ceiling, it is likely a very small under pressure there. But I have never measured it or seen measurements being made.

Sir please guide us on industrial fire in details like hydrocarbon fire, chemical fire

[@swedishfirenerd]

Maybe I will have time in the future to make some presentations on that. Right now I am very busy.

I don't get a particular piece: at around 48:30 there is the statement that if you are able to suppress the fire we would be able to start ventilating in order start searching for victims. Since we only suppressed (and not extinguish!) the fire, aren't we simply providing the fire with more oxygen? Or do we keep suppressing the fire from outside until we are able to reach and extinguish it (after rescue?).

[@swedishfirenerd]

To start ventilation, the easy answer is that the fire should be suppressed. Now the hard part is to judge if and when the fire is suppressed. My simplistic answer is that flaming combustion should be out and temperatures in the thermal imager should be below 150 degrees. It is a bit too safe in my opinion but it is a good starting position.
If the fire is suppressed, the fire will not grow suddenly with the addition of oxygen provided with the ventilation. So we can ventilate and receive all the positive aspects with that. But we need to keep monitoring the fire, either from inside or outside, to make sure it does not grow to big again and become a problem. Ideally this can be done with an exterior person so that the inside crew can focus on search. After search and rescue we come back and completely extinguish it and do overhaul.
