If you have enough liquid helium, it might smother the fire or cool the combusting materials that are supporting the fire so much that they are below their kindling temperature. However, this would be a very impractical fire fighting technique compared with using solid or liquid carbon dioxide, because carbon dioxide gas is denser than air while helium gas is much less dense than air. Furthermore, liquid helium is expensive and only rarely if ever available when one needs to fight a fire!
Note that the boiling point of helium is 4.22 K, −268.93 °C, −452.07 °F. From a practical standpoint it would be nearly impossible to maintain such extreme cryogenic conditions anywhere in the vicinity of a fire!

What is the word equation for liquid helium?
There is no word equation, except that helium will exist as liquid phase in liquid helium
Is liquid helium boiling a physical property?
Yes. conversion of liquid helium to gaseous helium is a physical property
What is the liquid and solid of helium?
Above -268.93 °C, helium is gas. Below -268.93 °C, helium is liquid. Helium cannot exist as solid.
Is liquid helium a true substance?
Yes it is. Helium will be liquid below -268.93 °C
Is helium a liquid at room temperature?
what is the density of helium at room temperature?
Is the sun liqid?
no, it's a constant explosion by gases known as helium, hydrogen. it is a fire, not a liquid.

Can you fight a fire with cryogenic helium?
In theory you could fight a fire with cryogenic helium, but in reality it would be exceedingly impractical and expensive. While helium is not extremely expensive, it is quite a bit more expensive than other substances normally used to fight fires - and much less plentiful. It is very expensive to lower helium to cryogenic conditions and the equipment necessary to maintain it at cryogenic conditions is also very expensive to build and operate. Note also that because it is such a light gas, it would quickly rise away from the fire, so it would require a lot more of it to fight the fire than if something heavier were used - like water, powder, or foam.
What is colder helium or hydrogen?
Liquid Helium is colder than Liquid Hydrogen.
Is liquid helium boiling a physical property?
Yes. conversion of liquid helium to gaseous helium is a physical property
What would happen if you poured liquid helium into liquid nitrogen?
The liquid helium would boil and evaporate.
What is the liquid and solid of helium?
Above -268.93 °C, helium is gas. Below -268.93 °C, helium is liquid. Helium cannot exist as solid.
Is liquid helium a true substance?
Yes it is. Helium will be liquid below -268.93 °C
Is helium a liquid at room temperature?
what is the density of helium at room temperature?
Which liquid boils the quickest?
Liquid helium in the helium I phase boils at about 5 K, lower than any other substance. (Liquid helium in the helium II phase does not boil, it simply evaporates. Helium is truly weird stuff at very low temperatures.)
Is helium conduct fire?
There is no such thing as "conducting fire." Helium is not flammable, if that's what you mean.
What type of foam to fight toxic fire?
all fires are toxic more or less. foam is generally used to fight liquid fuel fires as they form a blanket of air bubbles that prevents vapour from the liquid to mix with the oxygen present in the fire area.
