🔍 Key Concepts

• CFR 46 tank vessel construction requirements for cargo pumprooms and segregation • The definition and purpose of a cofferdam on a tanker • How ignition sources must be separated from flammable cargo vapors

💭 Think About

• Which option describes a dedicated, empty separation space designed for safety, not for carrying cargo? • Which choice provides both physical distance and a barrier between vapors and ignition sources, rather than just ventilation or a single wall? • Think about tanker design: what structure is commonly placed between cargo areas and machinery spaces or accommodation spaces?

✅ Before You Answer

• Verify which structure is defined as an empty or void space used only for separation and inspection, not for cargo. • Check 46 CFR tank vessel rules for how pumprooms must be segregated from machinery spaces and other ignition sources. • Eliminate any choice that could contain cargo or vapors under normal operations, since it would not provide true separation.
