Conductive Type C Bags
These are special bags which when the bag is earthed, allow static electricity to pass through it.
Fast filling and discharge of an FIBC by a powdered material causes static electricity to accumulate inside the bag. Further, to avert the dangers of explosion due to such accumulation of static charge, conductive properties are created in the bag; therefore the bag is earthed to allow safe discharge of electrical charge.
Type C bags are constructed using wall fabric that has a resistance to earth from any location on the FIBC of less than 108W. The FIBCs, provided they are grounded during use, are suitable to use in the presence of any potentially flammable atmospheres with either dust or gas vapour.
