Type C FIBCs refer to the class of FIBCs that actually protects against dangerous static discharges through grounding of the bag itself during the filing and discharging processes. These bags are safe when grounded because any electrostatic potential that builds up as a result of rapid filling or discharging quickly and safely exits the bag to ground via the network of conductive fibers woven into the fabric of the bag. This is true as long as the bag continually remains grounded.
