FDNY CoF – Torch Use of Flammable Gases in Laboratories (C-14) Practice Exam

Class K fires are specifically related to cooking appliances that utilize oils and fats, making them unique in the classification of fires. These types of fires can occur in commercial kitchens as well as in residential cooking settings where cooking oils or grease can ignite. Class K fire extinguishers are designed to effectively combat such fires by using agents that cool the fire's heat and saponify the burning fats, rather than spreading the flames as some other types of extinguishers might.

While Class A fires involve ordinary combustibles like wood and paper, Class B fires pertain to flammable liquids such as gasoline or oil, and Class C fires are associated with electrical equipment. These classifications highlight the specific nature of the materials involved in the combustion process, emphasizing the importance of using the correct type of fire extinguisher or suppression method for safety and effectiveness.
