🔍 Key Concepts

• Dry chemical extinguishing agents primarily interrupt the chemical chain reaction of fire rather than cooling it • Some extinguishing agents are not compatible with others (especially certain foams) and can reduce each other's effectiveness • Fires involving materials that contain their own oxygen supply (strong oxidizers) may not be controlled by normal smothering or chain-reaction interruption methods

💭 Think About

• Ask yourself: What is the main way dry chemical agents put out a fire: by cooling, smothering, or stopping the chemical reaction? • Consider whether mixing dry chemicals with foam is always safe and effective, or whether compatibility charts are needed in practice • Think about why fires involving oxidizers (which contain their own oxygen) can be difficult to fight with ordinary extinguishing agents

✅ Before You Answer

• Verify which option correctly matches the primary action of dry chemical agents (chain-reaction interruption vs cooling) • Check whether it is true in real firefighting practice that dry chemicals can be used with any foam or if that is too broad a statement • Consider whether materials with their own oxygen supply are typically listed as limitations rather than ideal uses for standard dry chemical agents
