What type of device is required to be installed on each LP-gas private, public or forklift refueling installation that includes a liquid dispensing system?

In an LP-gas refueling installation with a liquid dispensing system, an emergency breakaway device is essential for safety. This device is designed to prevent the undesired release of liquefied petroleum gas (LP-gas) during a situation where the dispenser may become disconnected, such as if a vehicle moves away while still connected to the dispensing system. The breakaway coupling allows the connection to separate safely, reducing the risk of spills and potential fire hazards.

The installation of an emergency breakaway contributes to enhanced safety protocols and aligns with the NFPA 58 guidelines, which emphasize the importance of preventing accidents and ensuring that liquid dispensing systems operate within prescribed safety standards. The use of such a device is critical for mitigating risks associated with refueling operations in various settings, including public and private refueling stations, as well as in forklift applications.

While other safety devices, such as pressure relief valves, flow meters, and automatic shut-off valves, serve important roles in an LP-gas system, the specific requirement for an emergency breakaway device directly addresses safety concerns related to accidental disconnections during refueling, making it the most appropriate answer in this context.
