视屏显示终端的职业危害

THE STUDY OF OCCUPATIONAL HAZARDS OF VDT

本文进行了视屏显示终端职业危害因素的监测及对操作人员身体影响的评价,表明其具有诸多的职业危害因素,主要为不良的微气候和空气离子状态,较低的照度、较强的噪声,尚有一定量的X线幅射及不良的人机关系。上述复杂的危害因素形成多方面的健康效应,主要表现在神经系统、精神行为、眼、骨骼肌、女性月经和生育方面,但以视屏显示终端作业工作量大的18岁～25岁年龄组较为明显。提示需加强对视屏显示终端作业人员综合性的职业卫生防护措施。

Both monitoring of occupational hazards and assessment of healthy effects on VDT operators were made. The results showed that there were several occupational hazards in VDT,including insalubrious microclimate and air ion condition, lower illuminance, higher noise, some doses of x-radiation, and unfitting ergonomics. The healthy effects of the hazards of the VDT mainly involved the operator's nervous system, psychology and behavior, eyes, musculoskeletal system as well as the woman operator's menses and pregnancy, especially in the 18 to 25 age bracket who had more VDT work hours than that of the others, it suggested that the various preventive measures against the hazards of the VDT must be strengthened.
