No single method exists for controlling all static problems. The proper use of equipment and remedial procedures help cure most static problems. Grounding: Static on a conductor can be easily controlled if the object is grounded. Grounding provides a path so that charge can migrate to ground, effectively neutralising the charge. However, grounding an insulator does not work, because charges do not migrate on insulators. Antistatic or static dissipative materials: Insulative materials, usually plastics, that are made conductive with the addition of carbon or metal fillings. The conductive dispersion can be adjusted depending on the amount of fillings added to provide resistivity ranging from fully conductive to dissipative. Ionisation: Air ionisers work by flooding the atmosphere with positive and negative ions. These ions are attracted to ions of the opposite polarity on a charged surface. As a result, the static electricity that has built up on products, equipment and surfaces is neutralised. Education: Training personnel and making them aware of electrostatic issues and the need for antistatic gloves, suits, smocks, and wrist/heel straps can make a large difference in the amount of problems that occur in a production facility.
