In the removal of product from a cargo tank, which step follows draining the product in loading/off-loading lines?

The appropriate next step after draining the product in loading/off-loading lines is to fit a 90-degree quick coupler to the discharge outlet. This action is crucial because it allows for a secure and efficient connection for further operations, particularly when you need to transfer or manage the remaining materials in the cargo tank. Using a quick coupler facilitates effective sealing and helps minimize the risk of leaks or spills during subsequent steps.

This step is strategically important as it prepares the discharge outlet for the connection of recovery or transfer hoses, which would be necessary for safe handling of the remaining product. It ensures that the system is ready to accommodate additional equipment, enhancing safety during the process.

While attaching a recovery line, opening the internal valve, or closing external valves are essential tasks during the overall operation, they would typically follow after ensuring that the discharge outlet is properly equipped and sealed with the appropriate coupler to prevent hazards.
