🔍 Key Concepts

• 46 CFR pre-transfer inspection and testing requirements for cargo tanks • Differences between high level / overfill alarms and other types of tank protection alarms • How often quick closing valves are required to be tested under 46 CFR

💭 Think About

• Look up the specific 46 CFR section that deals with pre-transfer inspections and list exactly which alarms must be tested before each cargo transfer. Which of the listed choices is not on that list? • Think about the purpose of each device: which are specifically there to prevent tank overfill during transfer, and which are more about general machinery or emergency shutdown protection? • Consider whether quick closing valves and low level alarms are normally tested on a fixed schedule (e.g., periodic maintenance) rather than before every transfer.

✅ Before You Answer

• Verify in 46 CFR which alarms must be tested immediately prior to cargo transfer (look for high level/overfill language). • Check if the regulation mentions low liquid level alarms at all in the pre-transfer testing section. • Check if the regulation requires quick closing loading valves to be operable, but not necessarily tested right before every transfer.
