The statement that is true about fire extinguisher classifications is: 'Class B fire extinguishers are for use on fires involving flammable/combustible liquids.' This type of extinguisher is designed to tackle fires that involve substances such as gasoline, solvents, grease, and other flammable or combustible liquids. Each class of fire extinguisher is designed for different types of fires and using the wrong one can be ineffective or even hazardous.
For instance, Class A extinguishers are used for ordinary combustibles like wood and paper, not combustible metals, which would require a Class D extinguisher. Class C extinguishers are for electrical fires only, and it is incorrect to say that only a Class C extinguisher must be used for a chemical fire. For chemical fires, especially ones from reactive substances like magnesium, one must use specific types of extinguishing agents, such as a Class D dry chemical fire extinguisher or sand. It's important to choose the correct classification to safely and effectively handle a fire situation.
Hence the correct answer is Class B fire extinguishers are for use ca fires involving flammable/combustible liquids
