Updated Static Dissipative Unit Ensures Safety of Type C FIBCSs for Hazardous Areas

An updated version of the Newson Gale Earth-Rite static electricity monitoring system provides an enhanced margin of safety when Type C FIBCs or similar static dissipative containers are used to transfer bulk powdered and other solid materials in hazardous area applications. The system consists of an enclosed intrinsically safe power supply and an electronic monitor. It continuously verifies the existence of a low-resistance path between the container’s static dissipative or conductive fibers and a known grounding point, typically through a mechanical grounding clamp affixed to a flexible tab. This new Earth-Rite monitoring system provides protection against an uncontrolled static discharge in a variety of hazardous atmospheres including combustible gas or dust, or an especially dangerous hybrid atmosphere comprised of both dust and solvent vapors. In operation, as long as safe operating conditions are confirmed the system displays a pulsing green multi-LED display indicating that the transfer can proceed. The system also includes a pair of DPDT control contacts which can be interlocked with the process controls to sound audible alarms or prevent the transfer from proceeding until a safe condition exists.
