Question 341 Deck General

The correct answer is A) 2-1/2 gallon foam. A 2-1/2 gallon foam fire extinguisher is classified as a B-II portable fire extinguisher, as per the regulations governing the requirements for fire extinguishers on commercial vessels. The B-II classification indicates that the extinguisher has a fire rating of 40-B:C, meaning it is suitable for flammable liquid (Class B) and electrical (Class C) fires. The 2-1/2 gallon size is the standard for a B-II extinguisher. The other options, while also portable fire extinguishers, do not meet the specific B-II classification. A 2 pound dry chemical extinguisher would be considered a B-I, and a 4 pound carbon dioxide extinguisher would also not qualify as a B-II.
