ABSTRACT:
The present invention is an apparatus and method for use in a flammable fluid distribution facility where a tanker truck or tanker ship onloads the flammable fluid and transports it to one or more locations. The present invention includes pumps for pumping the flammable fluid into the tanker and a monitor which monitors the tanker at the distribution facility to sense the presence and the strength of an electrostatic field and providing a field signal representative of the field strength of the electrostatic field. Circuitry connected to the monitor and to the pumps stops the pumping of the flammable fluid into the tanker when the field signal from the monitor indicates an unsafe strength of the electrostatic field.
