Earth-Rite® FIBC

Static Grounding for Type C FIBC Bags

The Earth-Rite FIBC system validates and monitors the resistance of Type C FIBC bags ensuring that the conductive elements of the bag are capable of dissipating electrostatic charges in compliance with IEC 61340-4-4 “Standard test methods for specific applications - Electrostatic classification of flexible intermediate bulk containers (FIBC)” and NFPA 77 “Recommended Practice on Static Electricity”.

The Earth-Rite FIBC system can be installed and setup to ensure that operators ground the bag before filling or emptying operations are started. During the bag filling / emptying process the Earth-Rite FIBC system continuously monitors the resistance of the bag so that if it rises above the recommended level of 1 x 107 ohms (10 meg-ohm) this dangerous situation can be indicated to operators and the process halted, either manually or via the system’s pair of NO/NC volt free contacts.

This feature ensures the generation and accumulation of static charges on the bag is stopped eliminating the risk of an incendive electrostatic spark discharge.

To compensate for normal wear and tear on Type C bags it is important to ensure the bag maintains its capacity to dissipate charge and also ensure the ground connection between the bag and plant earth grounding point is functioning correctly.

Newson Gale can also provide FIBC grounding systems that can validate and monitor Type C bags designed with an upper resistance threshold of 1 x 108 ohms (100 meg-ohm).

Resistance monitoring system

combined with machine interlocking output contacts (x2), ensures operators correctly clamp and ground the bag before  filling or emptying can commence.

Continuously monitors

the resistance of the bag while the process is underway, ensuring static charges have a safe static dissipative path to the plant earth ground.

Red and Green Pulsing LED indicators

tell operators whether or not a good ground connection is made.
