Question 1 of 27070

You are conducting training on firefighting procedures. What type of fire is characterized by the burning of flammable liquids, greases, etc., where a blanketing effect is essential?

🔍 Key Concepts

• Fire Classes by fuel type (ordinary combustibles, flammable liquids, electrical equipment, combustible metals) • The importance of a blanketing/smothering effect when dealing with burning liquids and greases • Matching the correct extinguisher type (foam, dry chemical, CO₂) to the fire class

💭 Think About

• Which fire class is specifically defined by fires involving flammable liquids and greases rather than solid materials or energized equipment? • For a fire where the fuel can spread across a surface (like oil on water or grease in a pan), why is a blanket over the surface more effective than just cooling with water? • Think about which fire class is typically fought with foam extinguishers that create a sealing blanket over the fuel surface.

✅ Before You Answer

• Confirm which class is for ordinary combustibles like wood, paper, rags, and trash • Confirm which class is for electrical equipment and which is for combustible metals • Identify the class that specifically mentions flammable liquids, oils, and greases and requires a smothering/blanketing method of extinguishment
