FDNY C-14 Practice Exam 2025 – Your Complete Guide to Mastering Torch Use of Flammable Gases in Laboratories Certification

Flammable liquids are specifically categorized under Class B fires. Class B fires involve the combustion of flammable liquids, such as gasoline, oil, and grease, which can produce heavy smoke and be difficult to extinguish with water. The appropriate extinguishing agents for Class B fires include foam, carbon dioxide, or dry chemical agents, which work to suppress the fire without spreading the flammable liquid. Understanding this classification is crucial for safe handling and effective response in laboratory settings where flammable liquids are present.

In contrast, Class A fires relate to ordinary combustibles like wood and paper, Class C fires involve energized electrical equipment, and Class D fires pertain to combustible metals. This distinction is important for selecting the right fire suppression method.
