Each class of fire requires a specific type of extinguishing agent to be treated effectively.

For instance, using water (a Class A extinguishing agent) on an electrical fire (Class C) could lead to electrocution or further damage. Therefore, understanding the classification and intended use of a fire extinguisher ensures that individuals can respond appropriately to various fire types.

The size of the extinguisher does matter in terms of how long it can discharge or how effective it can be in a large fire situation, but it doesn’t determine its effectiveness against specific types of fires. The color of the extinguisher is largely a standardization measure for quick identification and does not relate to its functional capacity. The location of the extinguis
