Which of the following is NOT a method of extinguishing fire?

Vaporization refers to the process of converting a substance from a liquid to a vapor state, which is not a traditional method of extinguishing fires. Instead, effective fire extinguishment relies on removing at least one element of the fire triangle: heat, fuel, or oxygen.

Smothering is an established technique used to extinguish fires, primarily by cutting off the oxygen supply, which is essential for combustion. Chain breaking can refer to disrupting the chemical chain reaction that sustains fire, often utilized in specific types of fire suppression systems. Saponification involves a chemical reaction that can be useful when extinguishing certain types of fires, particularly in scenarios involving fats or oils, reducing flammability.

In contrast, vaporization does not directly address any of the fire triangle components and is not recognized as a fire extinguishing method. Understanding these distinctions is crucial for effective fire fighting strategies and ensuring safety in fire-related incidents.
