What does an 'X' on a fire extinguisher label indicate?

An 'X' on a fire extinguisher label signifies the types of fires for which the extinguisher is effective. Fire extinguishers are classified according to the class of fire they are designed to combat, such as Class A (ordinary combustibles), Class B (flammable liquids), and Class C (electrical fires). The markings on the label help users quickly identify the extinguisher's appropriate use in emergency situations, ensuring that they can choose the right extinguisher for the specific type of fire they are facing. Understanding this labeling is crucial for ensuring safety and effective fire suppression.
