In many branches of the process industries, 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 even airborne dusts. In situations, where this risk exists, static grounding (earthing) and bonding clamps are required wher ...more
