🔍 Key Concepts

• Watertight integrity requirements for bulkheads and decks in 46 CFR • How non-metallic piping can affect fire resistance and structural strength • When metallic fittings or transitions are required for piping passing through watertight boundaries

💭 Think About

• Ask yourself: What is the main safety concern when a pipe penetrates a watertight bulkhead or deck on a vessel? Think about both flooding and fire spread. • Look at each choice and decide which one most clearly restores the strength and tightness of the bulkhead or deck around the non-metallic pipe. • Consider which option describes a method that the Coast Guard would consider standard practice for making a non-metallic pipe penetration safe and compliant.

✅ Before You Answer

• Verify which option specifically uses metallic components at the point of penetration through the watertight boundary. • Check which choice mentions that the fitting is securely attached to the bulkhead or deck in a way that maintains watertightness (e.g., welded or otherwise acceptable). • Eliminate any options that mainly focus on valve type or schedule of pipe but do not clearly address restoring the watertight and structural integrity of the bulkhead or deck itself.
