🔍 Key Concepts

• 49 CFR (Title 49 of the Code of Federal Regulations) covers transportation of hazardous materials in the U.S. • The International Maritime Dangerous Goods (IMDG) Code is the international standard for dangerous goods carried by sea. • Distinguish between hazardous materials regulations and general maritime safety conventions like SOLAS (Safety of Life at Sea).

💭 Think About

• Which CFR title is specifically dedicated to transportation and hazardous materials across all modes (highway, rail, air, and water)? • What is the correct full name of the international code that governs dangerous/hazardous goods transported by sea? Pay attention to small wording differences. • Do shipment requirements for hazardous materials by water come from vessel inspection rules, or from transportation/hazmat rules plus an international dangerous goods code?

✅ Before You Answer

• Confirm which CFR title actually contains the Hazardous Materials Regulations (HMR). • Verify the exact name of the IMO code used worldwide for sea transport of dangerous goods; watch for distractor names. • Check whether 46 CFR is mainly about shipping and vessel inspection versus multimodal hazmat transportation rules.
