🔍 Key Concepts
• 46 CFR Part 98 – Special construction, arrangement, and operation for portable tanks
• Differences between requirements for electrical equipment, lifting/handling, and hose connections when dealing with dangerous liquids in bulk
• Special signal requirements (flags/day shapes) for dangerous cargo transfer vs for certain specific cargoes
đź’ Think About
• For the electrical-equipment option, think about whether the regulation uses a fixed distance like "10 feet horizontally" or if it defines a hazardous zone differently.
• For the lifting/hoisting option, consider whether the regulations normally specify an exact number of portable tanks that may be lifted, or if they focus more on safe rigging and SWL (safe working load).
• For the hose-connection option, recall whether there is a specific minimum number of bolts required when pumping dangerous liquids from portable tanks that remain on board.
âś… Before You Answer
• Check 46 CFR Part 98 to see which one of these topics (electrical distance, number of tanks in a hoist, display of a red flag, number of bolts per hose connection) is explicitly stated in the regulations for portable tanks of dangerous liquids in bulk.
• Verify if a red flag by day is required specifically for sulfuric acid transfer, or if the signal requirements are different or more general for dangerous cargo transfer.
• Confirm whether the regulation gives an exact numeric requirement for bolts on hose connections when pumping cargo from portable tanks that stay on board.
