Question 1 of 27070

According to Coast Guard Regulations (46 CFR Part 92), a bulkhead capable of preventing the passage of smoke and flame for one hour would be classified as a/an __________.

🔍 Key Concepts

• 46 CFR Part 92 – Construction and Arrangement fire protection bulkhead standards • Differences between A, B, and C class divisions (what each one is designed to resist) • Meaning of the number (e.g., 60) in a fire division rating

💭 Think About

• Ask yourself: which class of bulkhead is specifically intended to prevent the passage of smoke and flame for a defined time period, and which is more about flame only or has lower requirements? • Consider how fire-resistance time (the “60”) combines with the bulkhead class (A, B, or C). Which combination is used for higher protection on steel ships? • Think about where in a ship you would want the strongest fire boundary (e.g., between main vertical zones) and which class of division would typically be used there.

✅ Before You Answer

• Verify in 46 CFR Part 92 that A-class divisions have requirements for construction material (e.g., steel) and fire resistance including smoke and flame for a specified period. • Check how B-class divisions differ in terms of their ability to stop smoke, flame, and heat, and for how long. • Confirm that C-class divisions have no requirement for fire-resistance time and what that implies about their use.
