Question 950 Deck Safety

The correct answer is C) 56. The symbol 56 represents the fire extinguishing agent or device best suited for a Class A fire, which is a fire involving ordinary combustible materials such as wood, paper, cloth, and plastics. The symbol 56 typically indicates a water-based extinguishing agent, which is the most effective for Class A fires. The other answer choices are incorrect because: A) 47 may represent a carbon dioxide (CO2) extinguisher, which is not the best choice for Class A fires. B) 36 may represent a dry chemical extinguisher, which is less effective than water-based agents for Class A fires. D) 26 may represent a foam extinguisher, which is primarily used for Class B (flammable liquids) and Class C (energized electrical) fires.
