All portable extinguishers are classified according to their:

• B. Color.
• C. Intended use.
• D. Contents.

Answer: (C)

Extinguishers are classified by the fires they’re designed to fight. Different fire types require different extinguishing agents, so the label on each extinguisher indicates the class of fire it’s suitable for (A, B, C, D, K) and often its effectiveness rating for those classes. That’s what “intended use” means in this context. For example, a water extinguisher is suitable for ordinary combustibles (Class A) but not for electrical or fuel fires, while a multi-class ABC extinguisher can handle A, B, and C fires. Capacity, color, or contents don’t determine the classification; they influence how much agent is available to discharge or what agent it is, but the classification is about the fire types it’s designed to combat.
