Arkansas Commercial Driver License (CDL) Practice Test

Class A fire extinguishers are specifically designed for use on fires involving ordinary combustibles like paper, wood, or cloth. Class B fire extinguishers can be used on flammable liquids like grease, gasoline, oil, or oil-based paints. However, they are not recommended for use in electrical fires, as their contents may be conductive and could result in an electrical shock. Class C fire extinguishers, on the other hand, are specifically designed for use on electrical fires. It is important to use the correct type of fire extinguisher for the type of fire you are dealing with to avoid potential hazards. Option B and C are incorrect because they do not mention the use of a Class C fire extinguisher, which is specifically designed for electrical fires. Option D is incorrect because it does not mention either Class A or Class C extinguishers.
