Question 53

The Correct Answer is A **Why Class A is correct:** Class A fires involve ordinary combustible materials that are typically organic, such as wood, cloth, paper, rubber, and many plastics. A fire involving trash and paper waste falls directly under this classification because the primary fuels are solid, organic materials like paper and general rubbish. **Why the other options are incorrect:** * **B) Class B:** Class B fires involve flammable liquids (like gasoline, oil, grease, paint, or solvents) and flammable gases (like propane or natural gas). Trash and paper waste are solid fuels, not flammable liquids or gases. * **C) Class C:** Class C fires involve energized electrical equipment. If the trash fire were caused by faulty wiring or equipment, the electrical fire would be Class C, but the fuel (trash and paper) itself is Class A. Since the question asks about the fuel classification of the trash and paper waste, Class C is incorrect. * **D) Class D:** Class D fires involve combustible metals (such as magnesium, titanium, zirconium, sodium, and potassium). Trash and paper waste do not contain these types of metallic fuels.
