There is no such thing as "conducting fire." Helium is not flammable, if that's what you mean.
Helium does not catch fire
yes it does
No, helium is not used in fire extinguishers. We find carbon dioxide (CO2) in some extinguishers, but not helium.
The thermal conductivity of helium is 0.1513 W/(m K)
Only at very high electric field strengths, sufficient to ionize some of the helium atoms.
No. Helium gas is just a gas. It is not flammable.
Helium hasn't an effect.
yes
with the gas helium or fire
No. Helium is a completley inert gas and is not known to undergo ANY chemical reactions.
Helium is non-reactive, there is no chance of it exploding.
There are many places and websites where one can learn how to conduct a fire drill. Most firehouse's will be more than happy to explain how to conduct these and may even offer to help demonstrate. Some websites that offer help on how to conduct fire drills are wikiHow, Volunteer Guide, and KidsHealth.
