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. WebJul 1, 2007 · A triangle flammability diagram for methane is shown in Fig. 1 —many hydrocarbons exhibit similar behavior. Point A in Fig. 1 shows a gas mixture composition of 60% methane, 20% oxygen and 20% nitrogen—this mixture is outside the flammability zone and therefore not flammable. The air line represents all possible combinations of …
