What is a potential consequence of using the wrong type of fire extinguisher on a fire?

Using the wrong type of fire extinguisher on a fire can lead to the fire spreading or intensifying, primarily because different types of fires require specific extinguishing agents to effectively put them out. For example, water should never be used on grease or electrical fires, as it can cause the fire to splatter or spread. Using an inappropriate extinguisher can react violently with certain combustible materials, exacerbating the situation rather than controlling it.

Therefore, it is crucial to understand the classification of the fire and select the corresponding extinguisher that is designed to handle that specific type of fire. This knowledge helps ensure the fire is suppressed effectively, minimizing the risk of spreading and ensuring safety.
