Grounding CROHMIQ FIBC Technical Note

Technical Note 133:
Grounding CROHMIQ® FIBC

CROHMIQ Static Protective FIBC Fabrics are designed and engineered to provide the highest level of safety demanded by industry without the need for grounding.

Static charge is dissipated safely by CROHMIQ fabric, thereby eliminating the risks associated with operator grounding errors and other Type C FIBC risks.

The safety of CROHMIQ FIBC when operated ungrounded is proven and qualified by testing in accordance with the International Standard IEC 61340-4-4: 2018.

In addition to meeting the safety requirements of IEC 61340-4-4, CROHMIQ FIBC meet the requirements for Type D FIBC as specified in IEC/TS 60079-32-1: 2013, CLC/TR 50404: 2003, NFPA 77: 2019, NFPA 652:2019, NFPA 654:2017 and JNIOSH TR No. 42:2007.

In some end user applications, the standard operating procedure is to ground all FIBC irrespective of type. In such applications, end users may require the presence of one or more tags on the FIBC to provide designated grounding points. The purpose of this Technical Note is to set out the requirements for grounding tags that may be attached to CROHMIQ FIBC.

There are a number of key facts to note:

Note: Only FIBC meeting the resistance to ground limits specified for Type C can be classified and used as Type C.

The requirements for grounding tags on CROHMIQ FIBC are as follows:
