In the event of a fire caused by isopropyl alcohol, which type of fire extinguisher should the nurse use?

When addressing a fire caused by isopropyl alcohol, the appropriate choice is a Type B fire extinguisher. This classification of extinguisher is specifically designed for flammable liquids such as alcohol, gasoline, oil, and grease. Isopropyl alcohol is a highly flammable substance, and fires involving flammable liquids require an extinguishing agent that can effectively smother the flames and prevent re-ignition.

Type B extinguishers typically contain either a foam or dry chemical agent that suppresses the fire by forming a barrier between the fuel and the oxygen, or by interrupting the combustion process. Other types of extinguishers, such as Type A, are meant for ordinary combustibles like wood and paper, Type C is for electrical fires, and Type D is designed for combustible metals. Thus, using a Type B extinguisher is crucial for effectively managing a fire involving isopropyl alcohol and enhancing safety in such situations.
