Conductive FIBC
Certain products generate static electricity during filling and emptying. This can lead to electric shocks, explosions and fire. The conductive FIBC allows the static load to dissipate safely.
Type C
Type C is the safest FIBC but must be earthed during filling and emptying. The static electricity dissipates by means of integrated carbon tapes which are interconnected and which are joined to an earthing point. Type C is suitable for use in zones 1 and 2 (explosive gas, vapours, and air mixtures) and in zones 20, 21 and 22 (explosive dust and air mixtures).
Type D
Type D discharges the static electricity into the atmosphere. This type does not need to be earthed, but must only be used if the immediate environment is not electricity-sensitive. Type D is suitable for use in zone 20.
Type B
Type B FIBC’s have a breakdown voltage upon the fabric (from the body and from the filling and emptying spouts) of less than 6Kv. This prevents static electricity charges which can even ignite dust particles and cause explosions. Type B is not to be used if the surrounding environment contains flammable gases and vapours but is suitable for use in zones 21 and 22.
