High levels of electrostatic charges are often generated on web materials as they are transported through the coating process. These charges not only affect the quality of the coating but present a serious safety hazard where solvent-laden coatings are used. An electrostatic discharge (ESD) event, occurring in or near the coater, can produce sufficient energy to ignite inflammable mixtures resulting in fire or explosion. The end result could be catastrophic with loss of life and extensive damage to machinery and the facility.
An electrostatic discharge to or from operating personnel can result in an uncomfortable electric shock or could be of a magnitude requiring medical attention. There is also the hazard of electrical shock causing a startle reaction, leading to injury from operating machinery.
By having a good understanding of static electricity and how to control it, these hazardous conditions can be reduced or eliminated, resulting in a safer, more productive, work environment.
