How should a firefighter react to a fire involving flammable liquids?

Using dry chemical extinguishers is the appropriate response when dealing with a fire involving flammable liquids because these types of extinguishers are designed to interrupt the chemical reaction that fuels the fire. They can effectively combat the fire by cooling the flames and preventing the ignition of nearby flammable materials.

Water, on the other hand, is not effective on flammable liquid fires and can cause the fire to spread, as many flammable liquids are lighter than water and will float on its surface. Smothering the fire with a blanket might work in very controlled environments but is not a reliable method for larger fires or those fueled by flammable liquids. Evacuating the area is important for safety but does not address the immediate need to control or extinguish the fire. Thus, the use of dry chemical extinguishers represents the most effective and safe method for a firefighter to respond in such situations.
