This includes all of the following measures:

  • equipment used to treat WEEE containing mercury is enclosed, under negative pressure and connected to a local exhaust ventilation (LEV) system;

  • waste gas from the processes is treated by dedusting techniques such as cyclones, fabric filters, and HEPA filters, followed by adsorption on activated carbon (see Section 6.1);

  • the efficiency of the waste gas treatment is monitored;

  • mercury levels in the treatment and storage areas are measured frequently (e.g. once every week) to detect potential mercury leaks.
