🔍 Key Concepts

• USCG portable fire extinguisher classifications (size I, II, etc.) • Difference between agent types: dry chemical, CO2, and foam • How minimum capacity is defined for each extinguisher size and agent

💭 Think About

• First, recall what the "B" and the "II" each mean in a USCG extinguisher rating. How does size category II compare to size I? • Think about whether different extinguishing agents (dry chemical vs CO2 vs foam) have the same weight/volume for the same rating, or if each has its own minimum requirement. • Ask yourself: if a B-II extinguisher could be any of these agents, would the Coast Guard specify one single minimum that applies to all, or separate minimums for each agent type?

✅ Before You Answer

• Check in the USCG tables that B-II has different minimums for dry chemical, CO2, and foam. • Verify whether each individual choice (A, B, C) actually matches the published minimum for B-II for that agent type. • Before choosing D, make sure that every single option is correct per the USCG minimum capacity table, not just one or two.
