Question 1 of 27070

According to Coast Guard Regulations (46 CFR), the piping, valves, and fittings for a fixed CO₂ fire extinguishing system shall have a bursting pressure of not less than __________.

🔍 Key Concepts

• 46 CFR requirements for fixed CO₂ systems on inspected vessels • Difference between working pressure and bursting pressure (safety factor) for fire-extinguishing piping • Typical storage pressure of CO₂ cylinders and how regulators set minimum design/burst values

💭 Think About

• First, recall the approximate normal operating pressure of high‑pressure CO₂ cylinders on ships. Is it closer to 800–900 psi or several thousand psi? • Then think: regulations usually require a safety factor above the maximum expected operating pressure. About how many times higher than working pressure is the required bursting pressure likely to be? • Compare that estimated bursting pressure to the answer choices and see which one best matches a realistic, regulation‑level safety margin.

✅ Before You Answer

• Check in 46 CFR Part 95 or 76 (fire protection) where fixed CO₂ systems are covered and look for the specific table or paragraph that gives a minimum bursting pressure for piping, valves, and fittings. • Verify that you are not confusing test pressure or working pressure with bursting pressure—the question is asking for the minimum bursting value. • Confirm that the option you choose is comfortably above normal CO₂ cylinder pressure and reflects a reasonable safety factor required by the Coast Guard.
