How To Distinguish Type C Bulk Bags And Type D Bulk Bags
Type C FIBCs, also known as conductive FIBCs or ground-able FIBCs, are made from non-conductive polypropylene fabrics interwoven with conductive threads sewn into the fabric. These threads must be electrically interconnected as well as connected to a designated grounding wire during filling and discharging. This connection to the ground or earth during filling and discharging is imperative to the safe use of Type C bulk bags.
Safe use for Type C bulk bags:
Transporting flammable powders.
When flammable vapors, gases, or combustible dusts are present.
Do not use Type C bulk bags for:
When ground connection is not present or has become damaged.
Resistance from any location FIBC to ground-able point.
Type D FIBCs are made from antistatic and static dissipative fabrics designed to safely prevent the occurrence of incendiary sparks, brush discharges and propagating brush discharges without the need for a connection from the FIBC to a designated ground/earth. Type D bulk bags such as Crohmiq™ bulk bags are manufactured with fabric containing quasi-conductive yarns that safely dissipate static electricity into the atmosphere via safe, low-energy corona discharge. Type D FIBCs can be used to safely package combustible products and handle products in combustible and flammable environments.
Safe use for Type D bulk bags:
Transporting flammable powders.
When flammable vapors, gases, or combustible dusts are present.
Do not use Type D bulk bags for:
When surface of FIBC is contaminated or coated with conductive material such as grease or other flammable and or combustible materials.
