Warning: Laser Printers Could Be a Health Hazard
by Delia Cruceru
Researchers from the Queensland University of Technology, Australia discovered a new health hazard in our offices: laser printers. According to them office laser printers pose a real threat to workers health because they spew out as much particulate matter as a cigarette smoker inhales. Lidia Morawska, Ph.D., and her colleagues studied 62 printers including popular models in the U. S. and Australia sold internationally under the Canon, HP Color Laserjet, Ricoh and Toshiba brand names. The study revealed that 17 of the printers were high particle emitters" because they released such elevated quantities of particles, the researchers think that is from the toner used in laser printers. 37 released no particles that would damage the air quality, six released only low levels, and 2 medium levels. Effect of inhaling these small particles can range from simple irritation to much more serious illnesses, including cardiovascular problems or cancer. "Even very small concentrations can be related to health hazards," said Morawska. "Where the concentrations are significantly elevated means there is potentially a considerable hazard." Most of the printers studied were from Hewlett-Packard. HP released this statement Wednesday: "HP is currently reviewing the Queensland University of Technology research on particle emission characteristics of office printers. Vigorous tests under standardized operating conditions are an integral part of HP's research and development and its strict quality control procedures. As part of these quality controls, HP assesses its LaserJet printing systems, original HP print cartridges and papers for dust release and possible material emissions to ensure compliance with applicable international health and safety requirements."related story: http://www.pcworld.com/article/id,135297/article.html
