A red square containing a letter on an extinguisher indicates it may be used on fires of which class?

Explanation:
A red square with a letter on an extinguisher shows which type of fire it’s designed to fight. The letter B stands for Class B fires, which involve flammable liquids such as gasoline, oils, and solvents. So this extinguisher is intended for fires of those liquids. It isn’t suited for ordinary combustibles (like wood or paper), electrical equipment, or metal fires unless it’s specifically rated for those classes as well.
