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 Wanhefeng™ 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: When the surface of FIBC is contaminated or coated with conductive material such as grease or other flammable and or combustible materials.
