There are four specific types of bags, each with unique features and safe uses. Please take some time to read about the different types of FIBC fabric and how they should and should not be used.
TYPE A FIBC’s
Type A FIBCs are made of plain-woven polypropylene and other non-conductive fabrics. FIBCs constructed of a fabric that does not have any protecting properties for the static charge.
♦This type of FIBC for non-flammable substances.
TYPE B FIBC’s
A type “B” bag is constructed from insulating fabric with a breakdown voltage of less than 6 kV. This provision prevents the risk of energetic sparks and propagating brush discharges which can ignite dust-air mixtures and flammable gases and solvent vapors.
♦Used safely to transport dry, combustible powders (MIE > 3 mJ)
♦There are to be no flammable solvents or gases present around the bag
♦DO NOT USE to transport flammable products (MIE < 3 mJ)
TYPE C FIBC’s
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.
♦Used safely to transport flammable powders
♦Used safely when flammable solvents or gases are present around the bag
♦DO NOT USE when the ground connection is not present or has become damaged
TYPE D FIBC’s
Type D FIBCs are made from anti-static 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.
♦Used safely to transport flammable powders
♦Used safely when flammable solvents or gases are present around the bag
♦DO NOT USE when the surface is contaminated or coated with conductive products such as water or grease.
