🔍 Key Concepts

• 46 CFR requirements for fixed and portable fire extinguishing equipment in machinery spaces • Differences in protection levels for small vs. high-horsepower steam propulsion plants • How boiler rooms are treated in fire protection tables for engine/machinery spaces

💭 Think About

• First, decide whether an 8,000 HP steam plant is considered a relatively small, medium, or large machinery space under 46 CFR fire protection tables. • Think about whether the Coast Guard typically scales fire extinguisher requirements linearly with horsepower, or in stepped categories (e.g., up to X HP, between X and Y HP, over Y HP). • Consider whether the boiler room might require more than the minimum for a generic machinery space because of the specific fire risk from fuel and burners.

✅ Before You Answer

• Identify the exact 46 CFR table or section that lists the minimum number and size of portable CO₂ extinguishers for machinery or boiler spaces by horsepower or space size. • Verify the extinguisher size category in the table (15 lb CO₂) matches the question before counting units. • Confirm whether the requirement states a minimum number per space or per square footage/horsepower range, and match that carefully to 8,000 HP.
