What does the labeling on a fire extinguisher indicate?

The labeling on a fire extinguisher indicates the class of fires it is rated for, which is crucial for ensuring the correct extinguisher is used on specific types of fires. Fire extinguishers are categorized into various classes based on the materials that are burning. For example, Class B extinguishers are designed for flammable liquids such as gasoline, oil, and grease. This information on the label helps users quickly identify the suitable extinguisher for a particular fire scenario, thereby enhancing safety and effectiveness in fire emergencies. Understanding the class of a fire extinguisher enables individuals to take appropriate action and prevents the risk of using an extinguisher that may not be effective against the fire at hand.
