Abstract
A breakaway separation prevention safety device that provides warning indicators reminding users to replace a fuel nozzle after dispensing fuel. The safety warning system reminds users of a fuel pump to replace the nozzle into the nozzle mount. The system is activated as the user removes the nozzle from the nozzle mount. An audio and visual warning is emitted as a reminder for the user.
