Question 1 of 27070

The most effective method of extinguishing a class "A" fire is by __________.

🔍 Key Concepts

• Class A fires (what materials they involve) • The primary way Class A fires are extinguished (what effect on the fuel is most important) • Difference between cooling, smothering, and dry chemical action

💭 Think About

• Ask yourself: What burns in a Class A fire, and how does that material usually keep burning? • Which extinguishing method removes the key requirement that keeps Class A fuels burning over time? • Which options sound more appropriate for electrical, liquid, or metal fires rather than ordinary combustibles?

✅ Before You Answer

• Confirm what Class A means (type of fuel: ordinary combustibles like wood, paper, cloth). • Match each option with the class of fire it is best known for (e.g., dry chemical vs. foam vs. water). • Identify which method focuses on reducing temperature below ignition point rather than mainly cutting off oxygen or preventing conduction.
