🔍 Key Concepts

• Class C fires (electrical equipment) and how they differ from Class A/B fires • Risk of electrical shock when water or foam is used near energized equipment • Standard safety step taken before working on or near electrical machinery

💭 Think About

• Ask yourself: What makes a Class C fire different from other classes in terms of hazards to the firefighter? • Which action removes the special danger associated with an electrically driven pump before you try to extinguish the fire? • Of the options given, which one actually changes the condition of the electrical hazard rather than trying to work around it?

✅ Before You Answer

• Verify which option directly eliminates the source of electrical energy to the equipment on fire. • Check which choice is a standard safety procedure before servicing or approaching electrical machinery. • Confirm that your chosen step would make it safer to then use water-based extinguishing agents if appropriate.
