🔍 Key Concepts

• Person in Charge (PIC) for transfer of dangerous liquid cargoes on tank vessels and tank barges • Specific USCG tankerman endorsements required for handling/transfer of liquid cargoes • Difference between deck/watchstanding ratings and cargo transfer specialists

💭 Think About

• Which of these credentials is directly tied to responsibility for loading/discharging/transfer of liquid cargoes, rather than general deck duties or vessel operation? • Look at which options are basic entry-level or deck ratings versus specialized endorsements for hazardous cargo handling. • Ask yourself: if a barge is loading flammable cargo, which credential would the Coast Guard require for the individual supervising that transfer?

✅ Before You Answer

• Verify which option includes the words tankerman or person in charge (PIC) in the endorsement title. • Confirm which credentials (if any) are specifically mentioned in 46 CFR as being required for cargo transfer operations on tank vessels/tank barges. • Eliminate any options that are general deck ratings with no direct connection to cargo transfer of dangerous liquid cargoes.
