Question 3730Deck General70% to pass
On a MODU, size III, IV, and V extinguishers are considered _______________.
AI Explanation
The correct answer is B) semi-portable.
On a MODU (Mobile Offshore Drilling Unit), size III, IV, and V fire extinguishers are considered semi-portable, as per the regulations in 46 CFR 108.495. These extinguishers are larger and heavier than the hand-portable size I and II extinguishers, but they are not permanently fixed in place like the fixed extinguishing systems. The semi-portable designation means they can be moved around the MODU as needed, but they require more than one person to transport them.
The other options are incorrect because hand-portable extinguishers are smaller and lighter (option A), fixed extinguishers are permanently installed (option C), and "all-purpose" is not an official classification for MODU fire extinguishers (option D).
