Water fire extinguishers are
the most common tools for tackling Class A fires, which involve ordinary combustible solids like wood, paper, cloth, and plastic. They work by spraying water under high pressure to rapidly cool burning materials below their ignition point, effectively “taking away the heat” of the fire triangle.
A dry powder fire extinguisher, often called a multi-purpose or ABC fire extinguisher, is a versatile safety tool used to tackle fires involving solids, liquids, and gases. It works by discharging a fine chemical powder that smothers flames, creating a physical barrier between the fuel and oxygen.
