🔍 Key Concepts

• Fire extinguisher size classifications on MODUs • Difference between hand-portable and semi-portable extinguishers under 46 CFR • How extinguisher size relates to whether it can be easily carried and operated by one person

💭 Think About

• Ask yourself: At what extinguisher size does it usually stop being easily carried by one person and start needing a hose or semi-fixed arrangement? • Which extinguisher sizes are normally mounted with a hose and sometimes a wheel or fixed bracket, instead of just a simple handheld unit? • Think about how the Coast Guard separates small, one-person units from larger units in their terminology.

✅ Before You Answer

• Verify in 46 CFR that sizes I and II are treated differently from sizes III, IV, and V. • Check which category is described as "hand portable" and which as "semi-portable" in the regulations. • Confirm that fixed systems are entirely different equipment (like CO₂ or foam systems serving a whole space), not just larger portable extinguishers.
