NFPA Portable Fire Extinguishers (NFPA 10) Practice Exam 2025 - Free NFPA 10 Practice Questions and Study Guide

In kitchen areas, the most appropriate type of extinguisher to provide is the Class K extinguisher. Class K extinguishers are specifically designed to combat fires that involve cooking oils and fats, which are common in kitchens, especially commercial kitchens where deep fryers are prevalent. These extinguishers utilize a special wet chemical extinguishing agent that not only effectively suppresses flames but also helps to prevent re-ignition by creating a barrier between the fuel and oxygen, cooling the flames, and saponifying the oils.

Class A extinguishers are effective against ordinary combustibles like wood and paper, not specifically tailored to handle the unique challenges presented by fatty or oil-based fires. Class B extinguishers are designed to tackle flammable liquids but do not provide the same level of effectiveness against cooking fires as Class K extinguishers do. Class C extinguishers are meant for electrical fires and would not be suitable for grease fires, which are the primary concern in kitchen environments. Thus, Class K extinguishers are essential for kitchen safety and effectively address the specific fire risks found in cooking areas.
