Considering a fire requirements fuel and also oxygen and heat to continue burning, is it feasible to put out a fire through lowering the ambient temperature below a certain point?


I am not a physicist, nor execute I pat one ~ above TV. But I think the answer is yes. IIRC, fire calls for fuel, heat and oxygen, and the removal of any type of one is sufficient to extinguish it. Yet I think you’d need a pretty short temp.

You are watching: Is it possible to freeze fire


Here we go: The Fire Triangle. Looks choose the best method of removing warmth is, um, dousng the fire v water.


Again the board ask what ns wondered because that ages but didn’t stroked nerves asking myself.

So if a match was frozen, would it refuse to light? Or if you carried a burn candle from one room to another that was similar in all elements except temperature, would it burn out much more quickly?

I constantly assumed that when something to be alight, the burning would certainly probably warmth up the remainder of the unlit product as that approached and also you’d continue to have combustion.


If a match were frozen, probably it would break apart once you tried come strike it?

For a fire currently started, sounds choose you need a radical fall in temp, not just the start of a cold snap.

Again the rebab.net ask what ns wondered for ages but didn’t bother asking myself.

So if a complement was frozen, would it refuse come light? Or if you carried a burning candle native one room to an additional that was identical in all aspects except temperature, would it burn out an ext quickly?

I always assumed that once something was alight, the burning would probably warmth up the remainder of the unlit product as the approached and you’d continue to have actually combustion.

for a match to ignite it needs to go above its ignition temperature. It could have one coldness that the quantity of warm you supplied, choose through friction in striking, would certainly not heat it above that point.

if the candle was carried into a room i m sorry froze the molten wax and also that in the wick then it would certainly go out.

your assumption is exactly for exactly how things remain burning.

if friend removed sufficient heat it would certainly go out.

though exactly how you remove warmth in a helpful sense likewise might influence another element. If you provided water come cool a fire friend would also deprive the fire the oxygen wherein the water is.

you can put a candle in a deep freezer through a video clip camera and also an oxygen sensor and also if the candle went the end while there to be still sufficient oxygen come support combustion then that would be an answer.


Back in grad college we held a superbowl party one January in Wisconsin. Us knew indigenous a couple of weeks earlier that the charcoal grill simply would not continue to be lit when it was bone-ass cold outside. So because that the Superbowl party, we bought a party of oxygen indigenous a welding shop, hooked increase a regulator and set up a trickle-feed via a copper tube right into the bottom of the charcoal.

We had actually great difficulty NOT burning our food come a crisp.


I locations where forest fires are periodically a difficulty the newscasters regularly say lower temperatures will help suppress the fire. I don’t recall any explanation.

I locations where woodland fires are occasionally a trouble the newscasters frequently say reduced temperatures will aid suppress the fire. I don’t recall any explanation.

forest fires room really the liquids and also solids that trees being turned into a combustible vapor prior to it is burned. The takes power in the form of warm for the fire come be me sustaining. Much less of this takes location when the wait temperature is reduced because much more heat needs to come from the fire itself.

also in warmer temperatures any water in the vegetation can be less, this water needs to be evaporated before the material have the right to burn.


When you blow on a complement or candle they walk out. You room not depriving the fire that O2, choose with water yet it quiet goes out. You are cooling the fire listed below ignition temperature.

if you offered water to cool a fire girlfriend would additionally deprive the fire of oxygen where the water is.

I go on a quick fire safety course in ~ the Heathrow plane fire station. The firefighter who ran the concept session claimed that, contrary to renowned belief, the main action of dousing a fire with water to be to reduced the temperature the the fuel and not to exclude oxygen.


this subject reminds me of just how the economic situation of mountain Francisco was stalled ~ the earthquake & fire because all the safes to be red-hot and also due to their mass would certainly take a long time come cool. The paper money within them was in perfectly great condition, but if the safes to be opened and air permit in, the fire triange would certainly be complete and also the money would certainly burst into flames.


I knew a “researcher” that was functioning on a proposal to use magnetic areas to inhibit/stop fires.

Forest Gump Voice : and thats every I have to say about that.

… the economic situation of mountain Francisco was stalled after ~ the earthquake & fire since all the safes were red-hot and also due to your mass would certainly take a long time come cool. The file money within them was in perfectly good condition, but if the safes were opened and also air let in, the fire triange would be complete and also the money would burst right into flames.

I need to question this. Like most flammable substances, record has an auto-ignition temperature - the attach says something favor 450 degress F. Compare that to the temperature the red-hot steel, which this link says is about 1000 degrees. And also if girlfriend raise the temperature of file to anything prefer that of red-hot steel, it will decompose also if (say due to the fact that of lack of oxygen) it can’t burn.

There’s also the allude that if you have actually a hot safe with great money inside, you need simply pour water top top it till it cools sufficient to handle - should take at many an hour or so.


I need to question this.

How around fire-resistant safes? nothing they have ceramic layers/other mechanisms to somehow limit what the internal temperature can obtain to for a couple of hours of high external temperatures?

If you open the door, you unexpectedly raise the within temperature over the autoignition temperature, and BLAZE


you could put a candle in a deep freezer with a video camera and also an oxygen sensor and if the candle went out while there to be still enough oxygen to support burning then that would certainly be an answer.

soot on the roof of my freezerrisk if setting refrigerants (usually flammable) top top fire - possibly explosively

One of those dont-try-this-at-home experiment eh?

So if a match was frozen, would it refuse to light? Or if you brought a burning candle indigenous one room to one more that was similar in all aspects except temperature, would it burn out much more quickly?

Would it? interesting question. Or would certainly it burn less bright?should be simple to check though.


I’ve done fire fighting courses in the past.

At one, our instructor discussed fires in roading tar. Reportedly a means they have the right to be extinguished is by adding much more tar. Making use of water is an extremely messy and can muck up the surface, even of the bits that aren’t top top fire. Friend can’t eliminate the fuel, therefore you minimize the temperature by adding cold tar.

As stated by ticker, water functions for most fires by lowering the temperature that the fuel. Yet sometimes you don’t want to use water because it needs to go somewhere when it’s to be squirted top top the fire and you might not want it to. Also, occasionally it will just bring the burning fuel away on height of it.

Breaking one side of the (heat, fuel, oxygen) triangle will extinguish a fire.

Yes, you deserve to freeze out a fire. The is largely what a CO2 extinguisher does. The effect of the heat absorption is greater than the oxygen deprivation indigenous the dry ice snow, but both mechanisms are in play.
