"....pretty cool till the family mutt jumped into the pool and grab a piece of dry ice.....and his entails came out under his real tail"

While noodling around youtube, I came across this interesting video and I immediately thought of the fire in Tennessee.
what?

Also, the area would need to be cleared of personnel, who would otherwise be smothered too (along with most of the fauna).
If it were possible to get at a reasonable cost, a Halon-based extinguisher (which puts out flames by chemical action rather than by smothering, and has a low toxicity to people and animals) would be the way to go.
Liquid nitrogen, in quantity, is about 1,000x more expensive than liquid water. Also, keeping it liquid while you are trying to get it to a fire requires massive amounts of specialized cooling equipment to keep it at -320 degrees F. Handling equipment is also problematic; one can’t just pump it through a fire hose, the hose would facture or explode.
Also, except for the immediate removal of heat in the area where it strikes the ground/water/flames, it returns to it’s gaseous state almost immediately. As a gas, it can only smother a fire where water can smother and remove heat over longer periods of time.
It’s just not worth it.
BTW: That idiot in the video with no protective gear on is lucky to have any skin left on his hands, feet or legs! A slip and he would have instantly frozen his skin and probably lost toes and fingers.
Some fires are NOT a bad thing for forests depending on the timber type.
Yet, whole tree skidding simulates fire. We can prevent these fires from happening, EVEN if human caused, if they would let us MANAGE THE FORESTS LIKE THEY SHOULD be managed.
I could write you page after page after page on this.
hmmm - what if you dropped pressurized containers of liquid nitrogen into the hottest parts of the fire - the resulting explosion and pressure wave might act similar to the way they use nitro/dynamite to shutoff oil-well fires. Wouldn’t want to do it anywhere near a firefighter due to possible shrapnel, but....
Watermellons!?
GREAT replies.
oh - take the idea for pressure wave with nitrogen and replace it with frozen pressure vessels of water would still get a pressure wave - question is would it be as quick or effective?
Hmmm is right ... what if ....
I always understood (from old navy days) that halon needed to be win a fairly confined space to really work effectively - wouldn’t atmospheric dispersion reduce it’s ability to work?
That’s a VERY intriguing idea. (artillery firing firefighting rounds of some sort)
Maybe that was also because there wasn’t a whole lot of halon in a discharge. If that problem could be overcome (large quantities, and maybe a halon-oxygen mix that would avert smothering problems for humans and beasts caught in it) then we’d have something that could be dumped on a large fire to put it out with little or no harm to humans and beasts.
Crazy energy to make liquid nitrogen. and you would need A LOT OF IT.
Cats are soooo devious............
You could be right - the nice thing is the forest wouldn’t be a concern about electronics damage from the residue LOL
His voice sounds like that genius guy on “Criminal Minds.”
The global ozone holeists, now global warmists, now climate changeists, would wring our necks for it, however.
Screwing around with liquid nitrogen without safety equipment is a BAD idea.
