In this article, we will explore the meaning behind these symbols and how they can help you effectively combat a fire.
Classifications of Fire Extinguishers
Fire extinguishers are classified based on the type of fire they are designed to extinguish. The symbols on a fire extinguisher provide a quick and visual representation of its classification. The most common types of fire extinguishers are:

- Class B: The symbol for Class B fire extinguishers signifies their effectiveness against flammable liquids, such as gasoline, oil, and grease.
- Class C: This symbol indicates that the fire extinguisher is safe to use on electrical fires, which involve live electrical equipment.
- Class D: Class D fire extinguishers are designed to combat fires involving combustible metals, such as magnesium, titanium, and sodium. The symbol for Class D extinguishers typically includes a letter “D” inside a yellow star.
- Class K: The symbol for Class K fire extinguishers is specifically used for fires in commercial kitchens, where cooking oils and fats are the primary fuel source.
Additional Symbols and Their Meanings
In addition to the classification symbols, there are other symbols on a fire extinguisher that provide important information:
