🔍 Key Concepts

• Classes of fire (A, B, C, D) and what burns in each class • What foam (AFFF or stored-pressure foam) is designed to do on liquid fuel fires • Why some fires (like electrical or metal fires) need very specific agents

💭 Think About

• First, match each answer choice to the type of material that is burning (solid, liquid, electrical, metal). Which fire class is each? • Think about what foam does when it hits a burning surface. Does it conduct electricity? Does it smother liquid fuels? Will it react dangerously with metals? • Ask yourself: which choice describes a situation where you most need to smother and cool a flammable liquid surface rather than protect delicate electronics or react with metals?

✅ Before You Answer

• Identify which answer choices involve flammable liquids, which involve energized electrical equipment, and which involve combustible metals • Recall that standard portable foam extinguishers are generally for Class A and Class B fires, and are not suitable for certain other classes • Make sure the option you pick is not primarily an electrical fire hazard and not a combustible metal fire situation
