ABSTRACT OF THE DISCLOSURE A safety arrangement for a gasoline dispensing station equipped with a vapor recovery system. Gasoline vapors displaced from a motor vehicle fuel tank during filling are collected through the dispensing nozzle, and are directed first through a flexible hose attached to the nozzle and then through a pipe to an underground storage system. A preferred embodiment of a break-away valve is placed in the pipe near where it enters the ground such that in the event of an accident, as by an automobile running over the gasoline dispensing console, the break-away valve will automatically close to shut off the vapor recovery system. This minimizes the danger of an explosion or fire possibly caused by an open vapor recovery system.
