Q

Which of the listed burning materials would be described as a class "B" fire?

🔍 Key Concepts

• Fire classification system (Class A, B, C, D, K) • Definition of a Class B fire • Difference between flammable gases vs flammable liquids vs cooking oils/grease

💭 Think About

• First, recall exactly what materials are covered under Class B fires according to standard firefighting classifications. • Look at each choice and decide: Is this mainly a flammable gas, flammable liquid, or another type of fuel? • Ask yourself whether all the listed materials fall under the same fire class, or if one of them belongs in a different class.

✅ Before You Answer

• Verify the formal definition of Class B fire (what kind of fuel and physical state). • Check whether acetylene falls into the same class as lube oil and grease, or a different one. • Confirm if grease and lube oil are treated as flammable liquids in fire class terminology, and whether that matches the Class B definition.
