Your welcome, sorry its taken so long.

Hi, thank for the comments. Yes he did a good job there, he was volunteers for that so kind of dropped in it a bit. Yes it's difficult with all the other ideas being thrown in, but he managed it well. Cheers

Hi, many thanks for the comment. A good question. We used to teach that during training with a vehicle that had no damage, the relief cut also enabled the roll to happen on a non crash damaged vehicle. We have change our methodology, so we now teach to tension a ram first as that will support the dash, in most cases of heavy frontal deformation we are just pushing the components back to their original position, so a relief cut isn't always required for it to be effective. So in summary, we should support the dash prior to any relief cuts in the base of the A-pillar. This video was done a long time ago and things have developed since. I should redo a video :) Take care. Jon

As a chemist, I can assure you you are 100% correct.

The fire would eventually sizzle out if it were a true sealer room. Think back to the Fire triangle, for a fire it needs Heat, Fuel and Oxygen. If you have a room with a fire that is sealed from having no more oxygen to burn other than whats in the room, that fire will consume the oxygen and slowly fizzle out as it doesn't have one of the 3 key components to a fire. A great way to see this oxygen usage yourself, and a fun experiment, Get a plate or a bowl and put a layer of water in it, put a candle in the middle of the plate or bowl, with the wick lit, then put a drinking glass over the candle, so the water helps create a perfect seal from any new oxygen being introduced. You'll see the flame gradually get smaller, and the water be "pulled" into the glass.

@@Jieeimuzu I am 28 years old and this is way cooler than any science project they let us do in school.( And now im gonna look for a candle.)

Flashover is the exponential growth of heat/fire resulting from temperatures reaching sufficient levels to cause rapid degradation of flammable materials supplying fuel to a rapidly growing fire

Hi that’s great to hear, thank you for the kind comment. Good luck. If you need any help let me know.

Hi Richie, thanks for the comment. Yes great question. It will predominantly be situation led. In this case spot on mate. Both front and back would be the emergency plan if a rapid removal is needed. In this case we had rear access. The front would be a potential but access to creat a viable egress was limited.

Thanks for the reply. Appreciate the videos

Your welcome. Let us know if you have any future videos you’d like to see 👍

Hi Callum Thanks for the kind comments, its good to hear the videos are still useful to Firefighters at all levels. there is also some useful material on the website www.rtc-rescue.com If we can be of any more help please get in touch.

@@RTCRescue great stuff, cheers 👍🏻

Thank you! Cheers!

Chaos is the natural order of things

@@iwontreplybacklol7481Seems like a contradiction in terms 🧐 chaos necessarily cannot have order

@@-dash what is called 'chaos' is purely subjective 😉

@@-dash it is a contradiction (but also a joke)

No problem, I hope it’s been of use. Take care

Hi, thank you for the comment. This was not a video to show the correct procedure for dash evolutions as such, it was part of a few videos introducing teams to the new equipment and how they can be used. The video briefly shows a dash lift not roll. You are correct, the norm would be in most cases to cut the A pillar last to maintain some form of structural integrity and to have a ram/spreaders in place to support the load. Which we have not demonstrated here. Thank you for the question, i hope that has helped.

Glad you enjoyed it!

Hi and thanks you for the comments. Yes that looks like a really useful bit of equipment, a lot has developed since the making of that video. It certainly would be a good addition to use with it. :)

Hi Mike Thanks very much for the kind comments. Yes, trying to show the benefits of vehicle relocation to aid vehicle rescue. Not always an option but often overlooked or not considered. 👍

Hi Yes sorry about the noise. I don’t know why. I keep forgetting to manage the generator noise when I’m talking. The wind is a pain in some videos too. Thanks for the comment. I’m no expert editor. 😉

@@RTCRescue I am always polite to the fire brigade I always give them a friendly wave with a friendly smile

Your welcome, thank you for the kind comments.

Thank you! Cheers!

Thank you for the kind comment 👍

Hi, thanks for the question. This technique seems to be pooping up in media more and more lately. It’s one of those techniques that can be very effective for some situations such as a frontal obstruction or a dash relocation where the front of the vehicle has under ridden a lorry or similar. Cutting the upper rail is ok if you have time and can get good access, on some vehicles the suspension transom/strut can be very close to the bulkhead which makes it difficult to get a full cut through. I have done it for both lift and roll and on the right vehicle it works really well, very effective. But is does take more time and you need to understand what you are trying to achieve before attempting it. Hope that helps 👊👍

Thanks for you reply! What you say makes sense. Seems to be a technique that some instructors want to see every time and others don’t use as much, so creates confusion. Thanks for all the videos, they are great training 👍

@@richie1553 your welcome. It’s another option for the toolbox. It’s not the best to always just do the same. Pick the most suitable option based on what you face and expected outcomes. Thank you for the kind comments. Take care.

Wrong, if you see the signs of a backdraft buidling up, ventilation will start the explosion. Cool down the hot gasses, prevent air from entering(oxygen) and STAY OUT !

There are various different scripts on what and why a Backdraft happens. This might help answer your question. “A backdraught is where limited ventilation can lead to a fire in a compartment producing fire gases containing significant proportions of partial combustion products and unburnt pyrolysis products (pyrolysates). If these accumulate, the admission of air when an opening is made to the compartment can lead to a sudden deflagration. This deflagration moving through the compartment and out of the opening is a backdraught. The force of a backdraught has the potential to damage building elements resulting in an unstable structure”

That's what she said ;)

Imagine if you just happened to open the door at exactly the right time and didn't know anything about backdrafts. You would be severely burned by that ball of flame that comes out. It's the firefighters nightmare. The other parallel hell for firefighters is Flash over.

awesome congratulations, thank you for signing up to my channel. :)

I removed my sub then brought it back so now you are the 99th sub

Thanks very much, good to know were getting it right, always happy to produce video on request. :)

Hi Matt Thats brilliant thanks very much for the support. Take care down there. Jon

Your welcome, thank you for the kind comments.

Hi Buddy, wow thanks for the kind words, its nice to know these videos are helping, yes i decided i would always make the videos realtime so if it goes wrong it shows the reality of extrication to some degree. If you ever want any videos doing on other techniques drop me an email. Many thanks mate, take care. John
