Static Earthing Interlock System

Static Earthing Interlock System

Precision and reliability is what the Earth-Rite® PLUS provides to QHSE professionals and engineers who are tasked with protecting personnel and plant assets from the ignition hazards of static electricity during railcar, skid, and IBC loading/unloading operations.

Conductive metal objects like railcars, LACT units, skids and IBCs that come into contact with electrostatically charged liquids can accumulate hazardous levels of electrostatic charge that could discharge static sparks with energies far in excess of the minimum ignition energies of a vast range of combustible gases and vapours. The ignition of combustible atmospheres by static electricity can be prevented by ensuring that such objects are earthed.

The Earth-Rite PLUS is the ideal solution for earthing and bonding a broad range of equipment at risk of igniting combustible gases and vapours. The Earth-Rite PLUS ensures that a continuously monitored 10 ohm, or less, connection is present between the earthed object and a designated true earth grounding point. This feature provides equipment specifiers with the ability to demonstrate compliance with the earthing and bonding recommendations of IEC 60079-32-1*, NFPA 77* and API RP 2003*.

*IEC 60079-32-1, “Explosive atmospheres: electrostatic hazards, guidance.”

*NFPA 77, “Recommended Practice on Static Electricity.”

*API RP 2003, “Protection Against Ignitions Arising Out of Static, Lightning, and Stray Currents.”

  • Interlock stops operation
    if the equipment connection or earth connection becomes faulty immediately halting the source of the static charge generation.

  • Attention grabbing LED indicators
    Simple and attention grabbing GO/NO-GO traffic light style LED Indicators show system status.

  • Complies with International Safety Standards
    Complies with International Safety Standards by confirming safe, low resistance static dissipation path (10 Ohms or less) from equipment to designated earthing point.

  • Heavy Duty Stainless Steel Earthing clamp
    suits all common tankers, drums, conductive plant items.
