Employees are the largest source of static electricity at many workplaces. Walking or sitting in certain types of chairs can generate voltage on the surface of the human body reaching several thousands of volts and if not promptly conducted, it can for example discharge through a sensitive device and lead to damaging/destroying this device. Anti-static mats are designed to conduct undesirable static electricity from the clothing and skin of employees. Using them also protects employees against unpleasant electrostatic discharge.
