🔍 Key Concepts

• Fire classes and what materials they involve (Class A, B, C) • How dry chemical agents work to interrupt the combustion process • Which fire classes are commonly marked on a standard dry chemical extinguisher label

💭 Think About

• First recall what types of fuel are involved in Class A, Class B, and Class C fires. Which ones are solids, liquids, or involve electricity? • Think about whether dry chemical leaves a residue that might conduct electricity or not. Is it generally considered safe for energized electrical equipment? • When you picture a common ABC dry chemical extinguisher on a vessel or in a building, which letters do you usually see printed on it?

✅ Before You Answer
