目的通过对某医院职业性汞中毒发病情况的调查,发现危险因素,积极采取措施预防医务人员职业性汞中毒。方法现场职业卫生学调查、工作场所空气汞浓度检测、历年职业健康检查和职业病诊断分析。结果①在某医院设备科、修理室等科室的工作台面、地面及其他工作场所发现有细小的汞微粒;②工作场所通风效果欠佳,空气汞浓度超过职业接触限值;③接触汞作业的25名医务人员中,6例被诊断为职业性慢性汞中毒观察对象,1例为职业性慢性轻度汞中毒,1例为职业性慢性中度汞中毒。经过改善工作环境后,时隔4年再无新发病例和观察对象出现。结论某医院汞危害严重,需要引起院方重视,要清除作业环境中的汞,并加强对汞作业人员进行汞危害培训。通过整改,有效预防了新病例的发生。 Objective To investigate the incidence of occupational mercury poisoning in a hospital and find out the risk factors and take active measures to prevent occupational mercury poisoning in medical personnel. Methods Field occupational hygiene survey, workplace air mercury concentration test, calendar occupational health examination and occupational disease diagnosis analysis. Results ① Fine mercury particles were found on the countertops, floors and other workplaces of a hospital equipment department, repair room and other departments; ② Workplace ventilation was ineffective with air mercury concentrations exceeding occupational exposure limits; ③ Exposure to mercury Of the 25 medical staff, 6 were diagnosed as occupational chronic mercury poisoning, 1 as occupational chronic mild mercury poisoning and 1 as occupational chronic moderate mercury poisoning. After improving the working environment, there were no new cases and observers after 4 years. Conclusions A mercury hazard in a hospital is serious and needs to be paid attention by the hospital. Mercury in the working environment should be removed and mercury hazard training for mercury workers should be strengthened. Through rectification, effectively prevent the occurrence of new cases.
