An antistatic wrist strap is used in EPA workplaces, Electrostatic Protected Areas (EPA), and dissipates the electrostatic charges of people so that highly sensitive electronic components, assemblies or circuit boards
are not damaged by electrostatic body discharges. Antistatic wristbands have a conductive layer and are connected directly to the protective earth via a cable
. They are applied to the wrist and discharge the static charge of the human body towards the protective earth.Underwriter Laboratory (UL) and have set voltage limits. They are used for assembly, testing or other work.
