Type C bags have interwoven conductive threads which are all reliably interconnected and MUST BE GROUNDED. Dangerous static charge is safely dissipated to ground.
Type C bags do not cause any discharges. But the most important condition is a reliable connection to ground during filling and emptying operations.
Type C To prevent grounding errors, Type C bags are additionally equipped with conductive loops in order to achieve contact to the hoist system, providing it has a path to ground
