What is a common extinguishing method for Alpha fires?

For Alpha fires, which involve ordinary combustibles such as wood, paper, and textiles, the most effective extinguishing method is the application of water. Water works by cooling the burning material and effectively lowering its temperature, which inhibits further combustion. This method is particularly suitable for these types of fires because it directly tackles the heat component of the fire triangle (heat, fuel, and oxygen) and helps to extinguish the flames.

The other methods, while effective for different types of fires or situations, are not typically advised for Alpha fires. For example, Halon is more effective on fires involving liquids or gases, whereas foam is ideal for flammable liquid fires. Spraying CO2 can be effective for fires involving electrical equipment or flammable liquids but is less effective for ordinary combustibles, as it might not address the heat effectively or could leave behind unextinguished embers. Therefore, using water remains the best choice for extinguishing Alpha fires.
