🔍 Key Concepts

• Class C (electrical) fires and what happens when power is secured • Effects of dry chemical agents on equipment and components • What parts of electrical systems (like contacts and relays) are sensitive to contamination or residue

💭 Think About

• Think about what a dry chemical extinguisher actually leaves behind on the surface of machinery and electrical gear. • Ask yourself which choice describes a realistic, common after‑effect that would concern an engineer during cleanup and re‑energizing the circuit. • Consider which options sound more like physical/thermal effects of water or heat, versus contamination or residue issues.

✅ Before You Answer

• Identify which option involves residue interfering with mechanical or electrical functioning. • Eliminate any options that would be more typical of using water rather than dry chemical on hot machinery. • Consider which outcome would require inspection, cleaning, or replacement of components before safely restoring power.
