Helium flammability
Webpredicting the flammability envelope since each inert has a different envelope. Fortunately all inerts except helium [due to its low molecular weight (hence buoyancy)] follow the calculated adiabatic flame temperature (CAFT) theory. A single envelope incorporating all the inerts present can be developed using this theory. Web11 jul. 2003 · The value is often determined experimentally, simply by igniting a mixture of hydrogen and helium in air, and then reducing the amount of hydrogen until the flame goes out. Using these approaches, the lower flammability limit of hydrogen in air is 4%. There is also an upper flammability limit of hydrogen of 75%.

WebHelium is not flammable and it is generally safe to use in many situations. Helium is an inert gas which is non-reactive, allowing for some unique uses from balloons and blimps … Helium (from Greek: ἥλιος, romanized: helios, lit. 'sun') is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements, and it does not have a melting point at standard pressure. It is the second lightest and second most abundant element in the observable universe, after hydrogen. It is present at about 24% of the tot…
