Question 723 Deck Safety

The correct answer is C) Class A, B, C, and D. Fires are grouped into different classes based on the type of fuel involved. The fire classification system used for US Coast Guard Captain's License Examinations follows the National Fire Protection Association (NFPA) standards, which categorize fires into Class A, B, C, and D. Class A fires involve ordinary combustible materials like wood, paper, and cloth. Class B fires involve flammable liquids and gases. Class C fires involve energized electrical equipment, and Class D fires involve combustible metals. The other answer choices are incorrect because they do not accurately reflect the standard fire classification system used for Coast Guard examinations.
