What should be prioritized when using a fire extinguisher?

The prioritization of choosing the correct type of fire extinguisher for the fire is crucial because different types of fires require specific extinguishing agents to be effectively controlled and extinguished. For example, using a water-based extinguisher on an oil or electrical fire can worsen the situation, posing significant dangers.

Understanding the classification of fires (such as Class A for ordinary combustibles, Class B for flammable liquids, Class C for electrical fires, etc.) allows a person to select the correct fire extinguisher type to ensure safety and effectiveness. Prioritizing the correct choice can mean the difference between successfully extinguishing a fire and exacerbating it, ensuring that a response is both safe for the user and effective in preventing further damage or injury.
