Abstract

The suggestion that VDUs, of which there were approximately 250 000 in Canada in 1980, are responsible for a variety of health problems has appeared in the scientific literature. An IRSST working group was formed to review current knowledge concerning the health hazards associated with the operation of visual display units, to recommend measures for the elimination of these hazards and the protection of workers, and to suggest avenues of future research.

A critical review of the literature characterized typical VDU environments, levels of electromagnetic radiation emissions, and the tasks, work organization and mental stress of VDU operators. The various health effects reported in the literature were also reviewed. These include disorders of the visual and musculoskeletal systems, dermatitis, photogenic epilepsy, stress, and disorders occurring during pregnancy. The report also presents recommendations concerning preventive measures, information and training, and the choice of appropriate technology.
