目的了解某蓄电池生产企业运行中存在的职业病危害因素及其危害程度,评价职业病危害防护措施及其效果,提出防护建议。方法采用职业卫生现场调查、检查表分析、职业卫生检测和职业健康检查等方法。结果该企业生产过程中产生的职业病危害因素有铅烟、铅尘、硫酸、噪声、二氧化锡等。产生铅烟岗位的铅烟40 h时间加权平均浓度(CTWA)为0.016~0.022 mg/m3,产生铅尘岗位的铅尘CTWA为0.026~0.042 mg/m3,有硫酸挥发的作业岗位的硫酸CTWA为0.65~0.94 mg/m3,二氧化锡CTWA为1.0 mg/m3,均符合国家职业接触限值。接触铅作业员工血铅检查项目均合格。结论该企业主要职业病危害关键控制因素为铅及其化合物、硫酸和噪声。其中铅及其化合物的关键控制点为装卸模焊接区域、焊过桥区域、焊端子区域、包片区域;硫酸关键控制点为加酸区域、充放电区域、化成区域;噪声的关键控制点为正极板铸板区域、装卸模焊接区域、焊过桥区域。 Objective To understand the occupational hazards and hazards of a battery manufacturer in operation, evaluate the protective measures against occupational hazards and their effects, and put forward the suggestions for protection. Methods The methods of occupational health field survey, checklist analysis, occupational health examination and occupational health examination were used. Results The hazards of occupational diseases in the production process of the enterprise were lead smoke, lead dust, sulfuric acid, noise, tin dioxide and so on. The results showed that the lead time for weighted average concentration (CTWA) was 0.016 ~ 0.022 mg / m3 at 40 h and that of lead dust was 0.026 ~ 0.042 mg / m3. The CTWA of sulfuric acid volatilization was 0.65 ~ 0.94 mg / m3, tin dioxide CTWA 1.0 mg / m3, are in line with the national occupational exposure limits. Contact lead workers blood lead inspection projects are qualified. Conclusion The key controlling factors of occupational hazards in this enterprise are lead and its compounds, sulfuric acid and noise. Among them, the key control points of lead and its compounds are loading and unloading die welding area, welding bridge area, welding terminal area and wrapping area; the key control points of sulfuric acid are adding acid area, charging and discharging area and forming area; the key control point of noise is Positive plate cast plate area, loading and unloading mold welding area, welded across the bridge area.
