🔍 Key Concepts

• SOLAS (Safety of Life at Sea) requirements for fire control plans • Differences between domestic and international passenger vessels • Thresholds based on gross tonnage (GT) and voyage type in 46 CFR fire protection rules

💭 Think About

• Ask yourself: Are SOLAS-style fire control plans mainly associated with ships on international voyages or only with size (tonnage)? • Consider whether U.S. domestic-only rules always mirror SOLAS, or if some requirements only apply when the vessel is on an international voyage. • Think about whether the wording "any vessel over 500 GT" sounds like a broad rule, or whether regulations usually tie such requirements to both tonnage and voyage type.

✅ Before You Answer

• Check in 46 CFR Subchapter H (Passenger Vessels) and Subchapter I (Cargo Vessels) for fire control plan requirements. • Verify whether the requirement is linked specifically to international voyages under SOLAS or applies equally to domestic-only voyages. • Confirm whether 500 GT is used as a minimum threshold together with the ship’s service/voyage type, not by tonnage alone.
