🔍 Key Concepts

• Title 46 vs. Title 49 of the Code of Federal Regulations (CFR) and which one deals specifically with hazardous materials transportation • Part 176 – Carriage by Vessel in the hazardous materials regulations • The section numbers in Part 176 that deal with preparation and stowage of cargo spaces/holds before loading hazardous materials

💭 Think About

• First decide which CFR Title is normally used for hazardous materials transportation requirements, especially by vessel: Title 46 (Shipping) or Title 49 (Transportation)? • Within that Title, think about whether the rules for preparing cargo holds would be closer to general inspection rules or specific hazardous materials carriage rules. • Look at the pattern of section numbers around 176.57–176.63 and think: which one is more likely to describe preparation of cargo spaces before loading, versus other topics like general conditions or segregation?

✅ Before You Answer

• Confirm which Title (46 or 49) is used for Hazardous Materials Regulations (HMR) for all modes of transportation, including vessel. • Verify that Part 176 is labeled "Carriage by vessel" and that it contains sections on preparation of cargo spaces/holds. • Check the section heading around 176.58 and 176.63 to see which one specifically mentions preparation of cargo holds or spaces before loading hazardous materials.
