Helaas is mijn engels niet toerijkend.

Fijn dat reakties weer mogelik is❤

(min34.50) Hello I called Deflected Attack the "transitional attack" inside the compartment it was explained in my book 2019 Riccardo Garofalo

Just curious to hear how much water was used to extinguish the car and the battery?

Super goed dat dit geoefend wordt. Wat ik mij dan wel af vraag is waarom dat met zo'n goede bus moet? Licht metalen velgen en dure componenten zijn dan kapitaal vernietiging. Zet die dan om naar stalen velgen met kale banden en haal die dure techniek eruit.

Onjuiste afkorting in de KZbin titel? Ultra High Pressure = UHP (niet UHD)

Werkt het nu wel goed op tablets en mobieltjes?

Nu wel met geluid 👏👏👏

Er was inderdaad iets mis met het geluid. Bekijk de video nu mét geluid -> kzbin.info/www/bejne/rpLFaqOEhpiCqs0

Laat eens zien of het nu wel op mobieltjes en tablets werkt..het is 2024 dus mobile first development toch?

LOL, geen geluid 😂😂😂 de uploader heeft niet eens even een check gedaan

ik ook niet

Ik hoor geen geluid onder de video

Zijn de kaarten in de video beschikbaar om te downloaden ?

What’s missing ?- SURFACTANTS. Smoke and fire gasses are hydrophobic (water repellent). That’s why ULFSRI revealed in their research that only 5% to 10% of water applied to a fire actually contributes to extinguishment. When all you use is water then the only side of the fire triangle you can impact is HEAT. So stop claiming that a straight stream of water cools fire gasses. Water cools HEAT. If you add a wetting agent that has surfactants the water molecules become hydrophilic and bond to the hydrocarbons in smoke and fire gasses. The temperature drops because the unburned carbons become too wet to burn and the fire gasses become too heavy to remain in the atmosphere. This is why the gasses cool. Water creates steam which expands the heat and causes it to dissipate. Try calling it “Heat Cooling” instead of gas cooling because that’s what’s happening with the chemistry and physics of the fire when all you use is water.

Hoe veilig of onveilig is een LiFePO4 accu in vergelijking met een Li-Ion of Li-Po accu?

Of bewust onwel natuurlijk.

Thank you, Karen. A presentation packed full of knowledge on people's movement & their behaviours.

Krijgen alle vrijwilligers dit pakket ook?

MAND!

Thanks for the explanation Dr Michael Reick

What he failed to mention was LFB ten years ago had 170 Pumps available and was the third largest fire Brigade in the world. In the 80's the Brigade had around two hundred machines available. Thanks to Mayor Johnson who became the prime minister this was reduced to 155 and then savagely 142 as revenge for firefighters going on strike to defend their pensions which they then won in court. Johnson (the PM who partied through Lockdown) and co basically stated 'fires don't occur anymore' so we don't need as many resources. The major incidents didn't though. Unfortunately the UK Fire Service for the last twenty years has suffered a major lack of funding with a double whammy since the 2002/03 fire strikes and then more austerity hitting in 2010. The Brigade embarrassingly doesn't even train its own firefighters and is reliant on a private company to do so (despite the fact it was cheaper to do it in house) and has sold its flagship training facility as well as its iconic headquarters on the Albert Embankment. The UK Fire Service is ran on a supply and demand basis these days not as a public service focused on risk and 'weight of attack'. Secondly forty fire engines were unavailable at one point during that period due to lack of personnel. So effectively we were down seventy Pumps on what used to be available ten years ago which would have mitigated some of the effects of the situation. Every day London is down Fire appliances during lack of riders. What a shit show!. The whole thing has been a political football completely mis-managed by politicians of both parties who ideologically hate the fire service. Obviously prevention and protection is one thing and you can't help the weather. To alleviate pressure in these situations I'd firstly start by getting the Brigade up to strength to crew what it has, and then expand with bringing it back to around 170 trucks which is a sensible number to be protecting London to ensure resilience. I'd also be looking at specification of frontline Pumps which generally are designed for dealing with metropolitan risks and hasn't changed since the end of World War II, e.g. some Brigades have 3000L tanks with a water shuttle capability, Some second Pumps could be equipped with 4x4 capability and CAFS (London doesn't even have that capability which many Brigades have in their wild fire arsenal) which could potentially assist, Water Bowsers and off-road vehicles. All this takes investment and political will which the UK Fire Service doesn't have.

Heel interessant en goed dat er al zo zorgvuldig wordt gekeken naar de risico's die gepaard gaan met de elektrificatie van onze samenleving. Zijn solid state batterijen straks misschien een veiliger alternatief?

KNAP 😊

Goede voorlichting video. Kleine tip: Kathode is Negatief en een Anode is Positief 👌🏻

Great speech

Oh John Jones, wat ben je toch een heerlijke droogkloot. "Wil jij uit naam van de brandweer wetenschap nog een keer gewoon plat op je muil in het water?"

Mooi wagenpark ook!

Ik wist niet dat er ook truck-opleggercombinaties zijn die met o&g kunnen rijden

I think it would have been far more interesting at 26:40 to show only the left side of the room... Because if you know the fire is on the other side of the box, maybe you'll think performing an "indirect attack" but if you don't know where is the fire, the same action will perform a "surface cooling". Same as the question about "smoke cooling". Notice one detail: the two sweedish guys you talk about at 32:04 were using Fogfighter. Of course, a Fogfighter is able to create smaller dropplets than the other nozzles that were available at this time but a Fogfighter is NOT able to create really small dropplet. If you want to have really small droplet which are really VERY effective at smoke cooling, you have to use a nozzle which flow rate can be set using a rotative ring like the POK Debikador, some from Akron, etc.. A nozzle on which the flow rate is set using the handle (slide valve handle for exemple) is NOT able to change the size of droplets according to the flow. Using a POK Debikador or similar nozzle, you're able to cool the smoke at low flow because with such a nozzle low flow = small dropplets and when you need to penetrate the fire plume and reach the "solid fuel", you can change the flow as in this case you'll get "big dropplets". There is also a problem of explanation: when the study about indirect attack was made, the nozzle available did not have a separate setting for flow and pattern. Nozzle were like these ones: www.deltafire.co.uk/products/fire-nozzles/marine-nozzles/unifire-v-series-nozzles/ With this nozzle, when you change the flow, you change the pattern. Using the Layman attack in interior mean the contex of the study was not well known. And when you say that if you close the door and use the indirect attack you'll get burned, that's true... and false. If you let the door open you can also been burned. Because the problem is NOT he amount of hot smoke or steam. The problem is "how the steam can escape?". So if you have a window or a door opened on the other side of the fire, you can produce as many steam as you want: the steam will go "over the fire" due to the pressure of you water flow, this will cool the fire and you'll not get burn. Concerning smoke expansion: the problem is not "expansion" but location. You have a smoke layer at ceilling level, and you flow throught this smoke layer; You will create a new layer of steam at ceilling level and this will push down the smoke and you'll loose visibility. So the "volume" of smoke dont' expand. Concerning you first problem which seems to be the difficulty in teaching, maybe it's more a pedagogical problem than a "technic" one. I've instructed a lot of firefghters and some of the guys at your presentation have been my students. In about 90% of the cases, after teaching them the technics and "how to teach", when going back to their fire station, they forget the "how to teach" part and focus only on technics. And after a few years or sometimes only a few month, all was lost... So in this case it's easier to incriminate the tools, the technics, and so one, than incriminate the pedagogical knowledge...

Een drietonige ambulancesirene? Dan moet dat wel heel erg oud beeldmateriaal zijn!

Fascinating, bet Joe Anderson hasnt watched where his brown envelope came from

Superb presentation with many thought provoking issues.

I've never understood the British resistance to sprinklers and fire hose reels.

Namens de collega's van kazerne Dirk. B3dankt

Het voorstel van Hans Hazebroek om bij een daadwerkelijke brand in een portiekflat direct op te schalen naar 4 keer een TS plus 2 maal een RV en 2 OVD's en GRIP 1, lijkt mij niet de bedoeling.

Heldere en belangrijke uiteenzetting. Ook belangrijk voor gebouwgebruikers om te zien waar de brandweer mee wordt geconfronteerd en hoe zij inzetten bij een brand/bij rookverspreiding. Belangrijke aspecten voor toekomstige ontwerpen en bouwprocessen om dit soort risico’s te gaan reduceren voor zover mogelijk (doelgerichte brandveiligheidsmaatregelen).

Typisch "onderzoek" praat.

Slecht uitgelegd om heel eerlijk te zijn.

Ofschoon de sheets niet altijd goed in beeld kwamen (understatement) presenteert Wojciech Wegrzynski toch een goed te volgen lezing over zijn onderzoek naar met name het nut van (stuwdruk) ventilatie in parkeergarages. Interessant vooral ook om de invloed van de hoogte van de parkeergarage in relatie tot (de capaciteit van) het ventilatiesysteem te zien. Zwaarder systeem is daarom niet altijd beter, integendeel.

Brilliant information and good presentation!

Wanneer een brandweerman met een gelaatstuk aangesloten op toevallig in het water valt sloeg het gelaatstuk van je gezicht af. In combinatie met de oude blus overall. Was te voorkomen door met een hand het gelaatstuk aan te drukken. Daar werd toen in den haag op getraind. Mijn compliment wat betreft jullie onderzoek. Had vroeger al moeten plaatsvinden. Lo

in de chat kwam het al aanbod, de automatische gasblussing. hier wordt op geantwoord dat windturbines hier niet mee zijn uitgerust. zelf ben ik laatst aanwezig geweest bij een incident waarbij kortsluiting was ontstaan in de schakelkast (10kv) onder aan de toren van de windturbine. deze schakelkast was voorzien van een automatische gasblusinstallatie, deze was ook geactiveerd bij aankomst. het betrof een Enercon windturbine van het type E-138 EP3, gelegen op windpark de kookepan. De parkbeheerder gaf aan dat elke schakelkast is voorzien van een dergelijke gasblusinstallatie maar kon ons op dat moment helaas niet veel informatie verschaffen over de gasblusinstallatie. wellicht interessant om hier nog eens naar te kijken.

Jullie bedankt voor al de leerzame webinars (tot nog toe)

I'm watching this next to my fully charged 140 cell DIY battery pack : /

Presentation starts at 10:44

This is a really fantastic presentation. It combines theory with great graphics and video observation, science, and common sense, practical guidelines/procedures-all with an admission of limited knowledge and change taking place in the field. The simple breakdown and desciption of the electrolyte components, itself, is not addressed like this elsewhere, and is worth the price of admission. Thanks.
