Anti-Static Manufacturing Accessories

Certain types of manufacturing involve complex, sensitive materials and devices that can be damaged or ruined by even slight changes in atmosphere or environment. Many industries, including telecommunications, electronics, and defense, require controlled manufacturing environments free of dust, debris, bacteria and other contaminants, but they also need to reduce or eliminate static charges. Even very small charges can disrupt or damage sensitive devices, or cause fires or explosions in flammable materials.

Static Electricity

Static electricity is an electrical charge that remains localized, as opposed to an electrical current, which is constantly moving. Static electricity accumulates when inductor materials, such as rubber or certain types of plastics, rub together. Inductor materials are those that do not conduct electricity very well. The friction mixes positive and negative charges in the ambient air and causes an electrical field to form on the surface. If this static electricity builds up too much, even small triggers can cause the surrounding air to become conductive and spark. Lightning is a very large scale example of static electricity: clouds mix together and bounce charges against one another, until there is too great a charge area and the electricity discharges in a lightning bolt.

While most static electricity is very small and, when it becomes electric current, the shock voltage is likewise diminutive, the effect of these shocks can be quite severe in sensitive operations.

Anti-Static Manufacturing Accessories

Because workers in manufacturing facilities like cleanrooms and factories can build up static electricity in a number of ways, there are various anti-static garments and other devices to help prevent incidents. Anti-static garments are common for workers producing electronics and flammable chemicals. These garments are typically woven or knitted fabrics of conductive wool that include metal strips or wires of copper sewn into them. The conductivity of both the fabric and the metal helps to decrease static accumulation while the worker moves around the facility and works with products and machines. The garments are full-body coveralls worn over street clothes, or in place of street clothes altogether.

However, anti-static garments are generally not enough to fully eliminate electrostatic discharge (ESD). A worker in an anti-static garment must also be connected to the floor to give an outlet for the charge. Wrist and ankle bracelet connections are available. These bracelets go around the limb, and then connect to the floor with a metal clasp at the end of a long rubber strap filled with carbon. Electrical charges that build around the worker flow down the strap and disperse into the ground, further limiting ESD.

In addition to garments and bracelets, facility installations are common antistatic devices. Many facilities use antistatic floor mats. These mats are made of dissipative rubber materials embedded with conductive metal strips, often copper. The mats are connected to the ground, or “earthed,” with a small cord composed of conductive materials. This connection helps direct electric buildup back into the floor, dissipating its charge and rendering it less dangerous.
