Question 1509Deck General70% to pass
For all loading operations, the terminal must supply the vessel with a means in which the vessel's designated person-in-charge may stop the flow of oil to the vessel, insuring immediate shutdown in the event of a hose rupture, tank overflow, etc. Which of the following choices will accomplish this task as required by 33 CFR?
AI Explanation
The correct answer is D) a pneumatically or mechanically operated device.
According to 33 CFR 156.120(a), during oil transfer operations, the terminal must provide the vessel's person-in-charge with a means to immediately stop the flow of oil in the event of an emergency, such as a hose rupture or tank overflow. A pneumatically or mechanically operated device, like an emergency shut-off valve, meets this requirement by allowing the person-in-charge to quickly and reliably shut down the transfer.
The other options, such as a loudhailer, lights, or a signal-board, do not provide the direct, physical control over the oil flow that a dedicated shut-off device does, and therefore do not comply with the 33 CFR regulation.
