🔍 Key Concepts

• Class A vs Class B bulkheads in SOLAS / 46 CFR for fire protection • Difference between flame passage and smoke passage requirements • Standard fire test time ratings (in minutes) for structural divisions

💭 Think About

• First, recall what the main purpose of a Class B bulkhead is compared with a Class A bulkhead. Is it primarily structural, insulation-related, or flame-containment? • Think about the typical time ratings used in marine fire protection (e.g., 15, 30, 60, 120 minutes). Which of these are usually associated with lighter divisions like Class B, and which are for heavier, main fire boundaries? • Look closely at which options mention smoke as well as flame. Does the Class B definition focus on smoke, flame, or both?

✅ Before You Answer

• Verify the official definition of Class B divisions in SOLAS Chapter II-2 or 46 CFR fire protection sections before choosing. • Check whether Class B bulkheads are required to prevent smoke passage specifically, or only flame passage. • Confirm the exact test duration (in minutes) for the standard fire test applied to Class B bulkheads.
