    It is essential to identify what role the device will play. Will it be required mostly for protecting sensitive electronics, for grounding personnel in assembly, or for in-line charge neutralisation during production? Examples include anti static wrist straps and mats for personal grounding and ionising bars and blowers for active charge neutralisation. Choosing the one that best applies helps to significantly reduce static-related damages.

  • Check the environment

    Another way to choose an anti-static device is to assess the working area. Busy areas such as electronics assembly or clean rooms require continuous electrostatic discharge monitoring and control. In such areas, permanent installations such as ionising bars or ceiling fans are appropriate. For flexible areas where devices generally need to be moved around, portable items such as anti-static sprays, mats, and wrist straps can be considered.
