Conductive bulk bag

1. Type B

Type B FIBCs are similar to Type A bulk bags in that they are made of plain-woven polypropylene fabrics or other non-conductive material. Also like Type A bulk bags, Type B bags do not have any mechanism for dissipating static electricity.

The difference between Type A & B FIBCs is Type B are made from materials that have a low breakdown voltage to prevent an incident where highly energetic, and dangerous propagating brush discharges occur. Although Type B bulk bags can prevent propagating brush discharges, they are not considered anti-static bulk bags because they do not dispel an electrostatic charge.

Safe use for type B bulk bags:

• To transport dry, flammable powders.
• No flammable solvents or gases present around the bulk bag
• Intended to be used in environments with dust with ignition energies less than 3mJ.

Do not use type B bulk bags for:

• When flammable solvents or gases are present around the bulk bag.

2. Type C

Type C FIBCs, also known as conductive FIBCs or ground-able FIBCs, are made from non-conductive polypropylene fabrics interwoven with conducting threads traditionally sewn in a grid pattern. These conducting threads must be electrically interconnected as well as connected to a designated ground/earth during filling and discharging. This connection to the ground/earth during filling and discharging is imperative to the safe use of Type C bulk bags.

Safe use for type C bulk bags:

• To transport flammable powders.
• When flammable vapors, gases, or combustable 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.

3. Type D

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 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:

• To transport flammable powders.
• When flammable vapors, gases, or combustable 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.
