🔍 Key Concepts

• Class A fires (ordinary combustibles like wood, cloth, and mattresses) • How different agents (water, foam, CO2, dry chemical) work on a fire • Which agents provide cooling and penetration versus only surface smothering

💭 Think About

• What material is a mattress mostly made of, and what class of fire is that? • Which of these agents is best at soaking into and cooling deep-seated, smoldering material? • Which agent might knock down visible flames but let the fire continue burning inside the mattress?

✅ Before You Answer

• Confirm which extinguishing agent is recommended for Class A deep-seated fires • Check which agent provides good cooling and saturation, not just surface smothering • Eliminate any agents that mainly work on flammable liquids or electrical equipment rather than ordinary combustibles
