🔍 Key Concepts

• 46 CFR requirements for dangerous (hazardous) materials on board • Difference between documentation/records versus signage or physical precautions • What the master or person in charge is specifically required to do on a recurring basis

💭 Think About

• Which option describes something you would have to do at regular intervals while the cargo is on board, not just once? • Which choices sound like good safety practices but are not necessarily a clearly stated regulatory requirement in that broad, general wording? • Think about how the Coast Guard or an inspector could later verify that you complied with the regulation—what evidence would they look for?

✅ Before You Answer

• Identify which answer involves a written record or log that can be checked by an inspector • Check if the option describes a requirement that could apply to any type of dangerous cargo, not just a specific hazard like fire or paint fumes • Eliminate answers that sound like one‑time actions rather than ongoing, periodic responsibilities
