🔍 Key Concepts

• Class C (electrical) fires and how they differ from ordinary combustibles • How dry chemical extinguishers are designed to interrupt the chemical reaction of fire • Why you must avoid creating a conductive path or splash when using an extinguisher on energized equipment

💭 Think About

• Think about what part of the fire triangle (heat, fuel, oxygen) the dry chemical stream is most effective at disrupting in an electrical fire. • Consider whether you want to bounce the agent, blanket the area, or focus it somewhere specific to safely and quickly stop combustion. • Ask yourself: what extinguisher technique would minimize the risk of spreading burning material or damaging sensitive equipment even more?

✅ Before You Answer

• Verify how dry chemical agents are supposed to contact the burning material itself in order to be effective. • Check which option describes a method that gives you direct control over the burning area, rather than an indirect or shielding effect. • Eliminate any choice that focuses on protection from shock instead of actually extinguishing the fire.
