A comprehensive guide to portable fire extinguishers, focusing on the classification of fires and the appropriate extinguishing agents. They detail the standard fire classes (A, B, C, D) based on the fuel type, such as ordinary combustibles, flammable liquids, energized electrical equipment, and combustible metals, respectively. The documents strongly emphasize the correct selection of agents, warning that using the wrong agent—like water on a Class B or C fire—can spread the fire or cause electrocution, and they also mention the specialized Class K for commercial cooking oils. Furthermore, the texts explain how to read extinguisher ratings (e.g., 2A:10B:C), which denote effectiveness in terms of water equivalency for Class A and square footage coverage for Class B fires, and discuss strategic placement rules, such as using ABC multipurpose dry chemical for general areas.
