Which of the following is NOT a type of fire extinguisher license?

Fire extinguisher licenses are categorized primarily based on the classifications of fires they are designed to combat. These classifications are generally aligned with the materials involved in the fire, such as ordinary combustibles, flammable liquids, gases, and electrical fires.

The letters A, B, and C refer specifically to extinguisher types designated for certain classes of fire. Class A extinguishers are meant for ordinary combustibles (like wood and paper), Class B is for flammable liquids (like gasoline and oil), and Class C is designated for fires involving energized electrical equipment. Each of these types is linked to specific training and licensing, allowing personnel to effectively manage different fire scenarios.

Class G, on the other hand, is not recognized in the conventional classification related to fire extinguisher licensing. This helps in identifying why this choice stands out as not being a type of fire extinguisher license. The absence of Class G from the recognized classifications emphasizes the importance of understanding which fire extinguisher types are valid and recognized in training standards.
