Class C fires involve flammable gases.
Fire hose used to apply water or other fire fighting agent directly to a fire or burning substance. Typically of 2 + 1 ⁄ 2 inches (64 mm) diameter or less in the United States. Historically 1.5 inch hose was the primary initial attack line but has been supplanted in most of the US by 1.75-inch-diameter (44 mm) hose that carries 175 gallons ...
Dry chemical powder is used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thereby separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire.

The larger the burn pan fire, the larger the rating and the longer the extinguisher must discharge to be able to handle the larger volume of fire before running out. For a given size extinguisher the resulting effect is a lower flow rate, resulting in a higher UL rating. Generally for same size extinguishers (agent capacity)
