Question 1921 Deck General

The correct answer is C) 15 lb. carbon dioxide. According to the small passenger vessel regulations, a B-II fire extinguisher is required. A B-II extinguisher is defined as having a rating of 40-B:C, which means it can extinguish Class B (flammable liquid) and Class C (electrical) fires. A 15 lb. carbon dioxide extinguisher meets this B-II rating requirement. The other options are incorrect because: A) 4 lb. carbon dioxide is a B-I extinguisher, B) 4 lb. dry chemical is also a B-I extinguisher, and D) 12 gallon foam is a B-III extinguisher, which exceeds the B-II requirement.
