Select research reports on health issues in video display terminal operations.
NIOSH 1981 Apr; :1-60
This document contained three reports which deal with the possible health issues among operators of video display terminals (VDT). The three papers discussed health complaints and job stress among video display operations, evaluated work station design factors in VDT operations, and surveyed the radiation and industrial hygiene concerns in VDT operations. In the first paper a questionnaire approach was used to gather data concerning working conditions, job stress factors, health complaints and psychological mood states among VDT operators. The results indicated that job content factors and VDT use contributed to the problems observed among VDT users in an interactive manner. The second study included an evaluation on site at five establishments using VDTs to assess current practices with respect to workstation design. The findings suggest that the illumination levels generally found were acceptable to most employees. A number of design problems were found, including excessive keyboard heights, and screen positioning which would require excessive inclination of the head and neck for screen viewing. Most of the users found screen readability, reflected glare, screen brightness and flicker to be problems. A number of dissatisfaction parameters were related to levels of health complaints. The results of the radiation study indicated the levels of x-rays and electromagnetic radiation emitted by a VDT were very low compared to current occupational standards.
