Which components are part of Coward's Triangle?

Coward's Triangle is a conceptual model used to illustrate the conditions required for combustion to occur, specifically in relation to explosive atmospheres. The triangle outlines three critical components: oxygen, a combustible gas, and the explosibility of the mixture.

Oxygen is essential for combustion; it acts as the oxidizer that supports the chemical reaction that occurs during burning. The presence of a combustible gas is equally important, as it provides the fuel required for combustion. Lastly, the explosibility refers to the mixture's ability to ignite and sustain combustion, which depends on the proportions of gas and air.

Understanding Coward's Triangle is crucial for safety in industries that deal with flammable gases, as it helps identify the conditions under which a potentially explosive atmosphere may form and informs procedures to manage risks associated with fires and explosions.
