Q

Which is the most effective fire extinguishing agent to use on burning linen?

🔍 Key Concepts

• Class A fires (ordinary combustibles like wood, cloth, paper) • Properties of water, CO₂, Halon, and dry chemical on different fire classes • How each agent cools, smothers, or interrupts the combustion process

💭 Think About

• First, identify what class of fire burning linen belongs to, based on the type of material involved. • Think about which extinguishing agent is best at cooling and soaking porous combustibles versus just smothering surface flames. • Consider which agents may quickly knock down visible flames but might allow deep-seated embers in fabric to reignite.

✅ Before You Answer

• Confirm which agents are normally recommended for Class A fires in standard firefighting guidance. • Check which extinguishing method is best at penetrating and cooling burning fabric, not just displacing oxygen. • Verify which agents on the list are more suited to electrical, flammable liquid, or gas fires, and rule those out for this situation.
