【摘要】：目的分析液晶显示面板生产项目中氧化铟锡(ITO)靶材维护保养时铟的职业病危害。方法采取现场职业卫生调查方法,根据国家现行职业卫生标准进行工作场所空气中铟水平检测,对45名维护人员采用电感耦合等离子体-质谱法检测血铟水平,并进行胸部CT检查。结果阵列、彩色滤光片和电容式触摸显示屏工序ITO靶材打磨工作岗位空气中铟的时间加权平均浓度(CTWA)和短时间接触浓度(CSTEL)存在超标情况,CTWA、CSTEL的最大值分别为2.98和10.20 mg/m3,最大超标倍数分别为28.8和33.0倍。45名ITO靶材维护人员胸部CT均未见异常;阵列和彩色滤光片工序的42名维护人员均未检出血铟,电容式触摸显示屏工序的3名维护人员均检出血铟(血铟水平为0.39~1.73μg/L),检出率为6.7%。结论该液晶显示面板生产项目ITO靶材维护保养时存在铟的职业病危害,应严格按管理制度操作,加强维护人员的个人防护,控制维护频率与持续时间,保障维护人员的职业健康。
[Abstract]:Objective to analyze the occupational hazards of indium tin oxide (ITO) targets in liquid crystal display panel production.Methods using the method of field occupational health investigation, the indium level in the workplace air was detected according to the current national occupational health standards. The blood indium level was detected by inductively coupled plasma mass spectrometry (ICP-MS) in 45 maintainers.Chest CT was performed.Result array,Color filter and capacitive Touch screen process ITO Target Grinding time weighted average concentration (CTWAA) and short time contact concentration (CSTELL) in the air of the working station are in excess of the standard. The maximum value of CTWAN CSTEL is 2.98 and 10.20 mg / m ~ 3, respectively, and the maximum exceeds the standard.The multiple was 28.8 and 33.0 times respectively. There was no abnormality in chest CT of 45 ITO target maintainers.No bleeding indium was detected in 42 maintainers in the array and color filter process, and the bleeding indium was detected in 3 maintainers in the capacitive touch screen process (the blood indium level was 0.39 ~ 1.73 渭 g / L ~ (-1)), and the detection rate was 6.7.Conclusion there is occupational hazard of indium in the ITO target material maintenance of the LCD panel production project. It is necessary to strictly follow the management system, strengthen the personal protection of maintenance personnel, and control the frequency and duration of maintenance.Safeguard the occupational health of maintenance personnel.
