When loading bulk liquid cargo, what is the FIRST action you should take if a cargo valve jammed open?
AI Explanation
The correct answer is B) Order the dock man to shut down.
When a cargo valve jams open during bulk liquid cargo loading, the first and most critical action is to immediately shut down the loading operation. This is to prevent an uncontrolled spill or release of the cargo. Ordering the dock man to shut down the loading is the quickest way to stop the flow and secure the situation.
The other options are not the correct first step. Running out a fire hose (A), calling the owner/operator (C), or tripping the pump relief valve (D) would not immediately stop the flow of cargo from the jammed open valve. Shutting down the loading operation is the priority to prevent a hazardous situation from escalating.
