Question 3677 Deck General

The correct answer is B) semi-portable. Size III, IV, and V extinguishers are considered semi-portable fire extinguishers according to US Coast Guard regulations. These extinguishers are larger and heavier than the hand-portable size I and II extinguishers, but are not permanently fixed in place like the larger size VI and VII extinguishers. Semi-portable extinguishers can be moved around a vessel but require more effort to transport and use compared to the smaller hand-portable models. The other answer choices are incorrect because: A) all-purpose is not a defined extinguisher classification, C) fixed extinguishers are permanently installed, and D) hand-portable refers specifically to the smaller size I and II extinguishers.
