Application of Static Grounding System in rail car loading & unloading operations
In
rail car loading and unloading operations, electrostatic build-up products are
transferred from storage tanks to tank cars through a loading system. As the
product travels through the conveyor system to the railcar, the molecules in
the product are charged with static electricity. If the railcar is not directly
grounded, it can build up static charge on its surface, which will cause the
railcar's voltage to rise sharply in a short period of time, causing a static
fire accident
Static
Grounding Monitoring Systems
The "Static Grounding Monitoring System"
functions as a part of an Overfill Protection & Earthing System. These
provide a visual green light indicating a confirmed grounding condition of road
tanker vehicles during the transfer of flammable and combustible materials. A
red light indicates the absence of dependable grounding. An interlock circuit
inside the control panel will prevent pumps and equipment from starting until a
satisfactory ground is established. The interlock circuit will also shut off
pumps and equipment if the ground is lost during the pumping operation.
