| Content | Problem Laser printers and copiers have become a perma- nent feature of today s offices. The possible health risks from dusts and gases emitted during the op- eration of such equipment are currently the subject of public debate. The Verwaltungs-Berufsgenos- senschaft (institution for statutory accident insur- ance and prevention in the administrative sector, Administration BG) has requested the IFA to in- vestigate the status quo and recommend protec- tive measures. Activities First of all, conditions that are scarcely realistic even in the worst case scenario were simulated in a small, unventilated test chamber. A number of commercially available colour copiers and black- and-white laser printers of different makes and designs were tested in continuous operation. The measured emissions were ozone, various organic substances (including carcinogenic benzene) and dusts including ultrafine particulates. To account for possible cumulative effects, the collected gases were assessed in the luminous bacteria test (Microtox®). Toner powders were also subjected to precise examination, e.g. for grain size distribution, dust- ing behaviour, and the content of metals and vola- tile organic compounds. In cooperation with the University of Essen, the effect of toner dusts on isolated alveolar macrophages (cells specialising in the removal of foreign matter penetrating into the lung) was studied. Laser printer in the test chamber Results and Application Even under unfavourable model conditions, the output of dusts of the A- and E-fractions was be- low the detection limit. When the test equipment was switched on, there was a temporary increase in the emission of ultrafine particulates. With con- tinuing copier/printer operation, the share of larger particles increased. All copiers/printers emitted volatile organic com- pounds (VOCs). However, the concentrations were well below the workplace limits and in most cases below the stricter environmental and indoor guide values as well. Ozone evidently is not a problem anymore; most of today s printers/copiers operate without emitting ozone. From the macro- phage test, toner dusts can be said to have an irritation and inflammation potential, albeit only at high concentrations.
