The Difference Between Type C and Type D Conductive Bags
1. Type C Conductive FIBC
Features: Discharges static electricity to ground via interconnected conductive wires
Purpose: Used to transport flammable powders
Type C FIBCs, also known as conductive or grounded FIBCs, were originally woven from a completely conductive material. Currently, grounded Type C FIBCs are more commonly constructed with a non-conductive polypropylene fabric interwoven with a conductive blend, typically in a grid pattern. This conductive blend must be interconnected to conduct static electricity to specific grounding points. These grounding points must be connected to the system grounding point throughout the filling and emptying operations.
2. Type D Conductive FIBC
Features: No grounding wire/ground contact required
Safe Use:
Used for transporting flammable powders
When flammable solvents or gases are present around the FIBC
Do Not Use:
If the FIBC surface is dirty or coated with conductive substances, such as water or grease. Type D FIBC is made of anti-static fabric that can safely and effectively prevent the occurrence of electric sparks, brush discharges, and propagating brush discharges without the need to connect the bag to the ground.
