What happens if an OPD is not functioning correctly during the filling process?

• A. The fill will continue without stopping
• B. The tank could overfill
• C. The filling process may halt unexpectedly
• D. Gas may leak from the tank

Answer: (C)

The correct choice reflects that if an Overfill Prevention Device (OPD) is not functioning correctly during the filling process, the filling may halt unexpectedly. OPDs are critical safety devices designed to prevent the overfilling of propane tanks by automatically stopping the flow of propane when the tank reaches a certain fill level. If the OPD malfunctions, it can lead to unexpected interruptions in the filling process, signaling either a failure in the mechanical operation or a fault detected in the system. While it's true that an OPD malfunction could potentially lead to a situation where the tank might overflow, the primary designed function of the OPD is to halt the process when it detects the tank is near its capacity. Therefore, if this device fails, the filling can stop abruptly to avoid further complications, including overfilling or gas leaks. Understanding this mechanism is crucial in ensuring safe propane handling and adherence to regulatory standards.
