Technical Assistance Report, No. TA-062-845, San Francisco Newspaper Agency, Chronicle, and Examiner, San Francisco, California.
Health hazards related to the use of video display terminals (VDT) were surveyed at the San Francisco Newspaper Agency (SIC-5199) in San Francisco, California, in November 1979 and January 1980. The survey was requested by representatives of the San Francisco Oakland Newspaper Guide Local Number 52 and the Bay Area Typographical Union Local Number 21 on behalf of an unspecified number of workers. Exposures to X-ray, radiofrequency, ultraviolet, and visible radiation were well below all occupational exposure standards. Air samples revealed no hazardous chemical exposures. Visual complaints were reported more frequently among VDT operators than nonoperators, and VDT operators reported more anxiety, depression, anger, fatigue, and confusion than nonoperators. Measured illumination at VDT work stations was generally acceptable, although glare was a problem. Excessive keyboard height and VDT screen height were also noted. The authors recommend adjustable keyboard and screen height and position, and VDT brightness and contrast to assure operator comfort. Chairs should have adjustable heights and backrests. Direct and reflected glare should be controlled by use of drapes or blinds, screen hoods, and antiglare filters. Lighting systems should be properly installed to eliminate or minimize glare. A work rest regimen is described for moderate and high work loads, and a visual testing program is proposed.
