Additional safety margin under real-life conditions

Users of HP laser printing systems can rely on tested toner, low release of material emissions and minimum particle emissions. Thus, there are no indications for health risks when HP laser printing systems are operated as intended. Furthermore, a variety of scientific results shows that an additional margin of safety can be assumed under real-life conditions in office rooms and work spaces.

Experts attest to safety of HP laser printing systems

HP constantly welcomes dialogue with health and safety competent bodies. In Germany, for instance, HP closely cooperates with the UBA (12), responsible German Professional Associations and experts for environmental hygiene to ensure user safety of HP LaserJet and HP Color LaserJet printing systems.

Independent experts and institutions attest to the safety of properly operated devices: a study on emissions at workplaces with printers and copiers in the offices of the Federal Bureau for Social Affairs, Family and Health in Thuringia demonstrated that laser printers do not figure as significant sources of dust emissions and therefore no health risk is to be expected.(15) The Professional Associations as well as independent scientific institutions of the Professional Association for the Administrative Sector, which regularly check emissions from office devices, either did not find any indications for an increased health risk due to laser printer emissions or toner dust.(16, 17)

In addition, experts from Germany’s Federal Government state that, considering real-life conditions, there are no indications for special health risks in the non-occupational sector.(11) In preliminary reports, the German Federal Institute for Risk Assessment summarizes results of a study on laser printer safety and states that both clinical examinations as well as real-room measurements do not indicate special health problems due to toner emissions.(18, 19)

The AGW is the limit for the time-weighted average concentration of a substance in the air of a workplace in relation to a given reference period. It specifies at which substance concentration acute or chronic negative health effects are usually not to be expected.
