Q

What are the required number and type of hand portable fire extinguishers to be carried, in the vicinity of the radio room exit, on a tank vessel on an international voyage?

🔍 Key Concepts

• 46 CFR requirements for fire extinguishers on tank vessels on international voyages • The difference between B-I vs B-II ratings and what type of fires each is intended for • Special fire protection considerations for areas near radio/electrical equipment on tank vessels

💭 Think About

• First, think about what class of fire is most likely near a radio room and its exit area on a tank vessel. Would that be flammable liquids, ordinary combustibles, or energized electrical equipment? • Next, recall which fire extinguisher class and size (I vs II) is normally specified by regulation for vital spaces and exits on tank vessels, especially where flammable vapors may be present. • Finally, compare the pre-2017 B-I/B-II designations to the post‑2017 numerical ratings (e.g., 10‑B:C, 40‑B) and match which size would logically be required at a radio room exit on a tank vessel.

✅ Before You Answer

• Verify which fire extinguisher class (A, B, or C) is appropriate for a tank vessel environment and for radio/electrical spaces. • Check whether the regulation calls for a smaller (I) or larger (II) unit near the radio room exit on a tank vessel. • Confirm how the old B-I/B-II categories correspond to the newer numeric ratings like 10‑B:C or 40‑B in the answer choices.
