ABSTRACT:
A safety shutdown system is provided for use with a fluid delivery system, such as used on a delivery vehicle. The safety shutdown system includes a plurality of sensors for sensing characteristics of a fluid delivery system. A controller includes a query timer function initiated in response to the sensed characteristic of the fluid delivery system and/or in response to activation of selected vehicle functions. The operator may repeatedly reset the query timer before it times out by pressing a button on a wireless transmitter. If the timer times out, however, the controller automatically shuts off a vehicle engine and/or closes a valve to prevent further fluid delivery.
