Abstract
Static electricity is generally harmless to the individual but it causes a lot of damage to products each year in the electronics and computer industry. As computers and electronics become ever more pervasive in consumer products so an increasing number of manufacturers will need to apply anti-static control measures. One such measure is anti-static apparel because people are the greatest source of static charge in the workplace. Electrostatic charge is most commonly created by the contact and separation of two materials. For example, a person walking across the floor generates static electricity as shoe soles contact and then separate from the floor surface.
The amount of static electricity we feel varies according to factors such as our body size, foot size, the material our clothes are made from and the soles of our shoes. Weather affects it as well; there is more build-up of static charge when the air is dry.
Most people feel harmless shocks at around 2,000- 4,000 volts. However electrical components can be damaged by as little as a few volts. It is estimated that between 8% and 33% of product losses the proportion of products which are rendered faulty -- are due to static electricity.
Anti-static clothing is required to prevent damage to electrical components or to prevent fires and explosions when working with flammable liquids and gases. If not controlled, static electricity can cause product damage and lead to machinery downtime, lost man hours, returned products and warranty costs particularly in the .
