What is the primary purpose of a breakaway device in a CNG delivery system?

The primary purpose of a breakaway device in a CNG delivery system is to stop gas flow in case of separation. In the event that the delivery hose is unintentionally disconnected or experiences a separation, the breakaway device is designed to prevent the release of compressed natural gas into the environment. This is crucial for safety, as it minimizes the risk of leaks and potential hazards associated with flammable gases. By immediately halting the flow of gas when separation occurs, the breakaway device enhances the overall safety of the CNG delivery process, protecting both the driver and the surrounding environment.

Other options pertain to different aspects of CNG systems. While managing gas pressure is important for overall operational efficiency, it is not the primary function of a breakaway device. Ensuring quick dispensation relates to the delivery speed but does not consider safety in the event of a disconnect. Checking gas quality is essential for compliance and performance but does not relate to the breakaway device's function. The focus of the breakaway device is solely on preventing gas flow during accidental separations to enhance safety during CNG delivery.
