Mueller Electric manufacture many different types of clamps, clips and assemblies, which are selected based on the items and materials to be bonded and grounded. Some important criteria to consider when selecting a bonding / grounding assembly include: Does the object being grounded have a paint or other coating that requires piercing? In what environment is the assembly to be used; how rugged does the assembly need to be? What type and size of clip is required? Are the objects being grounded stationary or do they need to move? What length of wire is required? Should the wire be insulated or non- insulated? Humidity Static has a tendency to accumulate more in dry environments, because any moisture in the air can help disperse the static charge on an object. Increasing the humidity in an industrial environment is not always feasible, but it is an option to consider. It is advisable to maintain a humidity level above 60% though the use of industrial humidifiers. Additives Antistatic additives to liquids such as fuel, can increase conductivity, helping to reduce electrostatic build-up.

The type of container should be a safety consideration when storing and handling flammable materials. Insulated and non- conductive materials increase the risk of static accumulation. Controlled filling speed and relaxation time The higher the flow rate of liquids, the higher the generation of static charges. Once dispensing is completed, it is best to wait before doing anything further to the equipment, such as opening lids, moving objects or cleaning. This relaxation time depends on the type of liquid. Summary Static electricity is an invisible hazard in many production, manufacturing and industrial environments. To protect workers, the equipment and the facility, proper bonding, grounding and other antistatic measures are of critical importance.
