BSFL Packaging offer a range of Bulk Bags manufactured and designed to manage the occurrence of static electricity safely during FIBC filling and emptying operations, which is a critical concern for many industries. As bulk bags are made from polypropylene, an electrically insulating material, they are prone to the build up of static electricity as friction and separation occur during filling and discharging of the products.
When filling and emptying the FIBC with a bulk product, a combustible dust arises inside the FIBC. Thus when filling and emptying the FIBC in hazardous areas with explosive atmospheres, a reliable protection against the risk of electrostatically induced ignitions is essential.
BSFL Packaging’s range of Conductive Type C Anti-Static Bulk Bags is designed for use with materials and in locations where it is essential to avoid the risks of electrostatic ignitions during handling.
BSFL Packaging offers the entire range of protective measures for the safe handling of FIBCs in hazardous areas. There are four types of FIBC in use according to their ability for charge dissipation and/or limiting the energy of possible discharges. The four types of FIBC are explained below:
|TYPE A||FIBC without any protective measures against electrostatic charges.
Don’t use Type A FIBCs in the presence of flammable vapours or gases.
|TYPE B||FIBC with a breakdown voltage not exceeding 6 kV to prevent propagating discharges. Type B FIBCs can be used in the presence of combustible dusts with ignition energies > 3 mJ.
Don’t use Type B FIBCs in the presence of combustible dusts with ignition energies ≤ 3 mJ.
Don’t use Type B FIBCs in the presence of flammable vapours or gases
|TYPE C||FIBC with interconnected electrostatic conductive film tapes and conductive loops and/or conductive tabs for grounding. The breakdown voltage does not exceed 6 kV. Type C FIBCs can be used in the presence of combustible dusts and in the presence of flammable gases or vapours with ignition energies ≥ 0,14 mJ.
When filling and emptying, the Type C FIBC must be grounded.
|TYPE D||FIBC made usually from non-conductive fabric containing conductive threads or filaments which are not interconnected. Charge dissipation occurs into the surrounding of the FIBC via corona discharge. Earthing of the Type D FIBC has only a minor effect on charge dissipation and is not required. Type D FIBCs can be used in the presence of combustible dusts and in the presence of flammable gases or vapours with ignition energies ≥ 0,14 mJ.|
