Translations: Fire extinguishing revolution! It is an exaggeration to say that it will be solved in an instant, but extinguish the fire from the inside and use a fire lance.

 Somewhere in the past, I learned that a fire hose was attached to the end of a long stick like a bamboo pole, and a spread shower was attached to it, and the window glass was broken and the water was poured into the room. I think he said it in passing.

...Maybe this idea is amazing?

Um...I want you to think for yourself, but wouldn't you think that if you poured a bucket of water on it, it would disappear in an instant? ··fire. ...It will disappear, right? At least, it seems like the area where the bucket of water was splashed will disappear soon. You can't imagine it not disappearing, right?

So, why aren't firefighting efforts going well? Maybe it's because you're spraying water from outside?

So, Fire Lance. flaming spear. A long iron pipe, like a bamboo pole, is attached with a spread shower nozzle at the end, and a fire lance is used to break through the window glass, spraying water from inside in all directions. If that's the case, it will likely disappear immediately from where it gets wet. It seems like the fire will be extinguished in an instant, right? ...It seems worth experimenting with.

One more thing.

Nowadays, it is possible to keep fire engine water connected to an outlet to keep it cold at all times using a refrigeration system. This also seems to have a great effect. When it cools down, the fire seems to go out easily. How about this idea as well?
