Question 1 of 27070

🔍 Key Concepts

• 46 CFR requirements for fixed gaseous fire-extinguishing systems in machinery spaces • How engine horsepower affects the required capacity/number of CO₂ extinguishers • Difference between portable fire extinguishers and fixed CO₂ systems in machinery spaces

💭 Think About

• Start by identifying where in 46 CFR Subchapter F or Subchapter I the rules for CO₂ protection of machinery spaces and diesel engines are located. • Think about how the Coast Guard scales fire protection requirements with increasing horsepower or volume of the machinery space. • Consider whether the question is asking for a single portable unit requirement or a total system arrangement made up of multiple 15-pound units.

✅ Before You Answer

• Verify the exact CFR table or paragraph that lists required CO₂ quantities for machinery spaces by horsepower or volume. • Confirm that the question is specifically about 15-pound CO₂ extinguishers and not total pounds of CO₂ or another type of system. • Double-check that you are looking at machinery spaces with internal-combustion (diesel) engines and not at accommodation or cargo spaces.
