Static Grounding Interlock System

Static Grounding Interlock System

Precision and reliability is what the Earth-Rite® PLUS provides to HAZMAT professionals and engineers who are tasked with protecting personnel and plant assets from the ignition hazards of static electricity during tank car, LACT & skid unit and tote loading/unloading operations.

Conductive metal objects like tank cars, LACT units, skids, totes 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 vapors. The ignition of combustible atmospheres by static electricity can be prevented by ensuring that such objects are grounded.

The Earth-Rite PLUS is the ideal solution for grounding and bonding a broad range of equipment at risk of igniting combustible gases and vapors. In combination with demonstrating the full range of Class I, Div. 1 approvals for all gas and liquid vapor groups, the Earth-Rite PLUS ensures a continuously monitored 10 ohm, or less, connection is present between the grounded object and a designated true earth grounding point. This feature provides equipment specifiers with the ability to demonstrate compliance with the grounding and bonding recommendations of NFPA 77*, API RP 2003* and IEC 60079-32*.

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

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

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