🔍 Key Concepts
• Fire extinguisher classifications (what does B-I, B-II, B-V mean in size/capacity, not just type of fire?)
• 46 CFR requirements for galleys on cargo vessels based on area in square feet
• Difference between minimum required protection vs. “more than required” protection
💭 Think About
• Look up the table in 46 CFR that lists the minimum number and size of portable extinguishers required for spaces with flammable liquids or cooking oils. Where does 2,500 sq ft fall in that table?
• Compare the minimum size rating needed for a galley of that area to the sizes represented by B-I, B-II, and B-V. Which option meets or just exceeds that minimum, without going way beyond what is normally listed as a requirement?
• Ask yourself: is there any requirement in the regs to have two different types or sizes together in a galley of this size, or is a single larger unit sometimes allowed?
✅ Before You Answer
• Verify from the CFR table what range of area 2,500 sq ft falls into and what minimum extinguisher size/number is listed for that range.
• Confirm which letter/number combination (B-I, B-II, B-V, etc.) corresponds to the minimum capacity required for that space type and size.
• Make sure the option you choose does not provide less than the required minimum protection; having more is acceptable, but the question is asking for the minimum that still complies.
