Why essential to select the correct extinguisher for the fire class?

Matching the extinguishing agent to the fire class is essential for safe and effective firefighting. Different fires burn for different reasons and respond to different controls. The right extinguisher works by the appropriate mechanism for that class—cooling the fuel, excluding oxygen, or interrupting a chemical reaction—so it can actually stop the fire without spreading it or creating new hazards. Using the wrong extinguisher can fail to suppress the flames, allow the fire to grow, or put you at risk. For example, throwing water on a flammable liquid fire can spread the liquid and cause a dangerous boil-over, and using water on an energized electrical panel can create a shock hazard. Conversely, a correctly matched extinguisher targets the specific class and reduces both damage and danger to you and others.
