When products are filling or discharge, an electric/static charge is generated. If this occurred in an explosive environment/atmosphere, it could serve a danger to life.
So, it is essential that we take all possible measures to prevent this discharge. The FIBCs (big bags/jumbo bags) needs to be created explicitly for anti-static properties and meet the provisions of international standard IEC 61340.
Provided that these bags are used accurately and that the regulations are complied with, & can guarantee for a safe workplace. The anti-static groups of our FIBCs are explained below.
Type A – 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 – FIBCs, like type A, become no protecting properties against the growth of static electricity.
The variation is that the fabric material has a lower disruption voltage (< 6 kV). This type of FIBC is for dry, combustible materials, but there must not be any flammable gasses in the area.
Type C – FIBCs are fabricated of conductive fabric. The conductivity is accomplished by knitting several conductive threads.
The different threads of yarn are combined and come together at an earthing point. Therefore, earthing of this FIBC at all times. This type of FIBC for flammable materials and in environments where combustible gases are present.
Type D – FIBCs are made of a special anti-static fabric with permanent discharge properties (corona discharge). They do not need to be earthed. However, it is crucial that the immediate vicinity (machinery, staff, etc.) is fully earthed. There are also restrictions on the relative humidity to use this type safely.
