Type B FIBC are made from virgin polypropylene added anti-static electricity master batch material that have a low breakdown voltage to prevent the occurrence of highly energetic, and dangerous propagating brush discharges (PBD).
Type B FIBCs are similar to Type A bulk bags in that they are made from plain-woven polypropylene or other non-conductive material. Similar with Type A bulk bags, Type B bulk bags do not have any mechanism for dissipating static electricity.
The only advantage to Type A is that Type B bulk bags are made from materials that have a low breakdown voltage to prevent the occurrence of highly energetic, and dangerous propagating brush discharges (PBD).
Although Type B FIBC can prevent PBD, they are not considered antistatic FIBCs because they do not dissipate electrostatic charges and so normal brush discharges can still occur, which can ignite flammable solvent vapours.
Type B FIBCs are mainly used to transport dry, flammable powders while no flammable solvents or gases exist around the bags.
Type B FIBCs should not be used where a flammable atmosphere with a minimum ignition energy ≤3mJ is present.
Spark discharges may occur from the surface of FIBC Type B if they become contaminated or coated with conductive material (e.g. water, grease or oil). Precautions should be taken to avoid such contamination and to avoid conductive objects such as tools or metal clips being placed on the FIBC.
