Question 35

The Correct Answer is B **Why option B ("Class B") is correct:** A paint locker contains flammable liquids (paint, thinners, solvents) and possibly flammable gases (aerosol cans). Fires involving flammable liquids or combustible petroleum-based products (like paint) are classified as **Class B** fires. **Why each of the other options is incorrect:** * **A) Class A:** Class A fires involve ordinary combustible materials such as wood, paper, cloth, trash, or plastics. While the locker itself might contain some Class A materials (e.g., rags or wooden shelving), the primary fuel source and inherent danger in a paint locker is the flammable liquid, making it a Class B classification. * **C) Class C:** Class C fires involve energized electrical equipment. Unless the fire was started specifically by a short circuit in an energized piece of equipment *within* the locker, the fuel source remains the flammable liquids, not the electricity. * **D) Class D:** Class D fires involve combustible metals (e.g., magnesium, titanium, zirconium, sodium, potassium). These materials are not typically found as the primary fuel source in a standard paint locker.
