Australian scientists have discovered that the laser printer, a standard fixture in virtually every office, can damage lungs in very much the same way as cigarette smoke. Almost one-third ofthe printers emit potentially dangerous levels of toner, according to a study by scientists from the Queensland University of Technology. Tests werecarried out on over 60 different models, with virtually one-third emitting minute particles that could infiltrate the lungs, possibly causing respiratory irritation or more chronic illnesses. The tests were conducted in a standard open-plan office, and particles levels rose fivefold during working hours, which the scientists blame on use of the printers. When new cartridges were insertedin the printer, or when graphics were being printed, the levels of toner in the air were significantly higher. The potential damage to lungs is similar to smoking cigarettes. Professor LidiaMorawska of QUT says the study serves as a warning to employers.
”Printers should operate in environments where there is as much ventilation as possible and as far as possible from where people’s desks are located.”
