ESD table mats as well as ESD flooring mats are primarily designed to conduct static charges to the ground. This way you prevent electronic circuit boards and other electronic products from damage by electrostatic charges. In combination with proper connected wrist straps we can discharge ourselves without damaging static sensitive components. Same counts for the combination ESD flooring and ESD shoes or shoe grounders.
When standing for long periods on hard surface in the ESD protected area, the ESD as well as the conductive and dissipative anti-fatigue mats are designed to reduce fatigue and at the same time eliminates static electricity by conducting to ground. Anti-fatigue mats absorb the shock when walking on hard surfaces and its cushioning effect stimulates and improves the blood flow and consequently reduces foot fatigue, back and neckproblems, absence from work, etc.
