PROBLEM: fires and explosions can result from electrostatic discharge in hazardous areas. Even relatively small sparks have sufficient energy to ignite many flammable vapours, gases, and airborne dusts. Where this risk exists, static grounding and bonding clamps are required wherever mobile or portable conductive plant items such as drums and vessels are used. It is necessary for the clamp to make a low resistance connection to enable static charges to be safely dissipated to ground before the energy available for discharge builds up to dangerous levels.

Most drums, containers and other equipment have coated surfaces from new, then often suffer build up of further insulating layers such as paint, resins, adhesives and sunstances inherent to the process environment. Tests have shown that ordinary grounding clamps often indicate very high resistance readings when clamped onto conductive objects with insulating surfaces. This may result in the clamp being physically attached in the eyes of the operator, but not actually dissipating static electricity safely. SOLUTION: Bond-Rite & Earth-Rite self testing and indicating grounding clamps, cables and monitors.
