Out-of-control EV blaze (thermal runaway) threatens to sink massive RORO ship.

It's typical extrapolation from facts: some fire brigades (not only in the Netherlands, but all around the world) have started testing/evaluating dipping the whole car in a container full of water. It sounds dramatic but it's actually simple: such containers are simple and plentiful, can be easily transported around using existing infrastructure, water is cheap and plentiful, and dipping the whole car simply removes the need of the "garden hose" man as you described it. It's an obvious idea, so it's obviously being used.
Now, is this needed? Of course not, it's nctnico's interpretation not backed up by any source or any sensible reasoning. Quite the opposite, if such measures were the only way to stop EV fires, we would be all doomed because these fires happen and in most cases there is no such container available. It's also worth noting Tesla specifically advises against it, this would be pretty weird if it was "necessary".

>The responding crew got caught in the flash reignition of the liquids, but thankfully, they were protected by their PPE.
The same dreaded reignition, but orders of magnitude faster and thus more dangerous.
>third-degree inhalation burns to the throat, trachea, possibly lungs. Facial burns around the mouth and nose area
>third-degree burns to the scalp, neck, eyes and face.
>third-degree burns to the hands and wrists.
>the gear, when exposed to the extreme high-heat temperatures, starts to off-gas.
> a simple fuel spill fire is enough to push the gear to those limits
>be mindful of what is flowing out from the vehicle and where you are standing in relation to it, and then start extinguishment from a distance before moving closer.
Sounds all pretty nasty.

498 ev's, the company apparently released a statement to stop speculations. I can't find it.
Some sites report there was also a dutch pilot and german surveyor on board. Surveyors are often on board when tests are being performed.

Interesting, i still can't find anything in german except the number 25.
I do not know enough to know if it ultimately matters though. Once the ship is burning, it's burning.
I can't imagine that BEV or ICE makes much of a difference in this case, since that is not the reason for the difficulties with extinguishing this particular fire.

I'm not sure of the point of your post. You continue to make false statements like comparing the water used to fight an EV fire to the water used to fight an ICE fire, when water is not recommended for an ICE fire when gasoline is involved.
Where are the equivalent guides for ICE vehicles. I can't seem to find them.
So, what are you trying to say?

Here you go a guideline for ICE vehicles that touches on the exact issue of cars involving flammable liquids:
https://www.firerescue1.com/fire-products/personal-protective-equipment-ppe/articles/firefighter-safety-reminder-car-fires-are-class-b-fires-aHIOlyst4ZAmA2Z6/
The article says that water is appropriate while foam is recommended. However this is for actual firefighters that know the dangers of using water on a flammable liquid and have protective equipment to save them from the situation you see in the video.
For the average joe without appropriate training and wearing no protective equipment you are definitely NOT supposed to use water in this situation.
Context is important. If you think firefighters should not use water, go explain that to them.
EDIT: Keep in mind that even when using foam, the same can still happen, it is just less likely.

It is amazing how politicised EVs have become, if you read the news it'd seem like this is the next environmental catastrophe, a boat with some cars on fire, yet in relative terms the Deepwater Horizon spill is still being cleaned up and cost BP some $65 billion dollars in compensation. Some areas will never again be viable for fishing because the fish are not considered safe for at least 100 years.

Yes, remember this?: At least two dead in oil platform fire in Gulf of Mexico? Problably not, it was only 3 weeks ago!
The dipping of the car in a container with water is only to transport the extinguished car to a yard where it will stay for weeks to prevent re-ignition.
Then it will be scrapped. The electrolyte is pyrophoric, this means it can reignite in air.
I have seed some video's of fire trucks with a special skid plate they can shove under a car and pump water through to cool the battery.
