WebThe term is a nickname for flammability diagrams that refer to the composition of gas in the air of an environment. Certain combinations of gases in the air can lead to a risk of ignition and fire. The Flammable Triangle speaks of a range in which ignition is most likely. It has a lower flammability limit and upper flammability limit. Web, of methane (CH. 4), propane (C. 3. H. 8), ethylene (C. 2. H. 4), carbon monoxide (CO), and hydrogen (H. 2), and some of their binary mixtures. It also addresses the issue of the flammable concentration (flammability) limits of these pure gases in air. The study is based on spark ignited explosions in large, spherical laboratory vessels
