随着公交事业的大力发展,地铁作业中存在哪些劳动卫生及职业病问题,是摆在我们面前的一个新课题。我们对地铁变电室着火在场的15名工作人员,进行了住院全面的检查。由于吸入了大量的橡胶、聚氯乙烯塑料、合成纤维板燃烧后的混合性烟雾,所有患者均有程度不等的胸闷、气憋、咳嗽、头晕、恶心等主诉症状。客观检查8例心电图ST-T有改变,3例肺功能小气道功能降低,其它无异常所见。但在特殊化验方面,N-乙酰-β-D-氨基葡萄糖苷酶(NAG)活力与正常对照组进行比较,有明显的改变见下表。
With the vigorous development of public transportation, what labor hygiene and occupational diseases exist in the subway operation is a new task before us. We conducted a comprehensive hospital inspection of 15 staff members who were present at the scene of the subway transformer room fire. Due to the inhalation of a large number of rubber, PVC, synthetic fiber combustion of mixed smoke, all patients have varying degrees of chest tightness, gas hold back, cough, dizziness, nausea and other main symptoms. Objective examination of 8 cases of ECG ST-T have changed, 3 cases of pulmonary function small airway function decreased, the other no abnormal findings. However, in the special test, N-acetyl-β-D-glucosaminidase (NAG) activity compared with the normal control group, there are obvious changes in the table below.
