Static Grounding for Process Plant & Equipment
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*.

* Recommended Practice:“Where the bonding/earthing system is all metal, the resistance in continuous earth paths typically is less than 10 Ω. Such systems include those having multiple components. A greater resistance usually indicates that the metal path is not continuous, usually because of loose connections or corrosion.”

“Pressure-type clamps should have sufficient pressure to penetrate any protective coating, rust, or spilled material to ensure contact with the base metal with an interface resistance of less than 10 Ω.”
