Question 3734 Deck General

The correct answer is B) II. According to the regulations, on a Mobile Offshore Drilling Unit (MODU), an extinguisher with 15 lbs. of CO2 or 10 lbs. of dry chemical is considered a size II extinguisher. This is based on the Coast Guard regulations that specify the size and capacity requirements for fire extinguishers on different types of vessels, including MODUs. The other options are incorrect because a size I extinguisher is smaller (less than 15 lbs. of CO2 or 10 lbs. of dry chemical), a size III extinguisher is larger (more than 15 lbs. of CO2 or 10 lbs. of dry chemical), and a size IV extinguisher is even larger than a size III.
