摘　　要：目的了解朔州市某高岭土厂职业病危害现状,为该厂日常职业卫生管理提供参考依据。方法对生产过程中存在的职业病危害因素浓度/强度进行检测,采用职业卫生调查法和检查表法对其生产过程、职业病危害防护措施、职业卫生管理等进行调查、分析与评价。结果该高岭土生产过程中存在的主要的职业病危害因素有其他粉尘、噪声、一氧化碳、二氧化氮、一氧化氮、二氧化硫、高温等。检测结果显示:包装岗位粉尘超标,TWA为15.79 mg/m3,超限倍数为3.25,打散岗位噪声超标,8h等效声级89.6dB(A),其余岗位和工种均符合国家职业接触限值标准。该企业生产工艺先进、自动化程度较高,建立了完善的职业卫生管理体系,设置了防护设施,配置了个人防护用品。煅烧岗位未设置应急救援设施,打散岗位出现双耳高频听力损失。结论某高岭土厂职业病危害的关键控制点为粉尘、噪声、一氧化碳。包装机需设置有效的防尘排风设施、打散岗位隔声间应改造、煅烧车间需增设应急救援设施。Objective To understand the current status of occupational hazards in a kaolin production enterprises in Shuozhou city,so as to provide reference basis for the daily management of occupational health in the factory. MethodsTest was done on the concentration/strength of occupational hazard factors in the production process.Occupational health survey and checklist were used in investigation analysis and evaluation of production process occupational hazard protective measures and occupational health management. Results The main occupational hazard factors in this kaolin production process included other dust,noise,carbon monoxide,nitrogen dioxide,nitric oxide,sulfur dioxide,high temperature and so on.The test results showed that the dust of the packaging post exceeded the standard,and TWA was 15.79 mg/m3,the excursion limit was 3.25.The noise of the scattered post also exceeded the standard,and the LEX,8 hwas 89.6 dB（A）.The remaining posts and jobs all met the standard of OEL.The company wasadvanced in production technology and had a higher degree of automation.It had established a perfect occupational health management system,and set prevention facilities,equipped with personal protective equipment.There was no emergency rescue facilities in the calcination jobs,and high frequency hearing loss of both ears had been found in the break up post. Conclusion Thecritical control points on occupational hazards in a kaolin production enterprises are dust,noise,and carbon monoxide.The effective dustproof facilities and ventilation system should be equipped in packing machine,the isolation booth of break up post should be reformed,and the emergency rescue facilities of the calcination workshop should be added.
