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.
