Type B bulk bags
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.
