The flammability experiments with H2-air mixtures at an initial pressure from 25 mbar to 1000 mbar have been performed within the entire range of flammability 4-80% of hydrogen in air. An overview of all the tests is shown in Fig. 3. Every experimental point indicates “ignition” or “no ignition” event.Helium chemical properties showed that it is non-flammable and does not explode at all. Even if it comes into contact with fire, it just pops no matter how huge the balloon was. But hydrogen, it is highly flammable. Hydrogen gas forms explosive mixtures with air in concentrations (4-75%) with very wide flammability range compared to other fuels.Flammability testing determines how easily a material or finished product will ignite or burn when close to fire or heat. It is therefore extremely important for maintaining safety around products used in residential, commercial and industrial environments.Second, even though helium is the second most abundant element in the universe—hydrogen is the first—helium is exceedingly rare on Earth. Helium is formed by the decay of radioactive elements in the Earth’s crust.

Abstract. Compared with pure helium, the hydrogen and helium mixtures with proper proportion can improve the performance of pulse tube refrigerators in the temperature range from 20K to 40K. Because hydrogen is flammable and explosive, the safety of the system can not be ensured once the hydrogen and helium mixtures inside leaked out.Helium has a molecular weight of 4 and, like hydrogen is lighter than air. While helium is not as light as hydrogen, it is inert and non-flammable (unlike hydrogen, which is highly flammable). For this reason, helium is used to inflate party and meteorological balloons as they will rise in air.Despite being the second most abundant element in the universe (second only to hydrogen, helium’s lighter and more flammable cousin), helium isn’t found just lying around on Earth.For example, two hydrogen atoms combine to become a bigger, heavier helium atom. You can read more about nuclear fusion (and nuclear fission) here. ... To summarize, oxygen is not flammable by itself, but it can cause other objects to ignite quickly and rapidly (a property that makes oxygen an excellent oxidizing agent) and set things …Helium chemical properties showed that it is non-flammable and does not explode at all. Even if it comes into contact with fire, it just pops no matter how huge the balloon was. But hydrogen, it is highly flammable.
