对某企业发泡车间429名异氰酸酯作业工人进行问卷调查、体格检查、工作班前及班后呼气峰流速监测、肺功能检查,研究支气管哮喘发病及防护情况。发现45.4%的作业工人无防护意识,不佩戴任何防护用品;作业工人支气管哮喘患病率为3.0%;工人班前、班后峰流速变异率为-9.9%~29.63%。提示异氰酸酯可引起峰流速下降,致少数工人患支气管哮喘。
429 isocyanates workers in a foaming workshop in a certain enterprise were surveyed, physical examination, monitoring the expiratory peak flow velocity before and after the work class, examining pulmonary function and studying the incidence and protection of bronchial asthma. Found that 45.4% of workers did not have protective awareness and did not wear any protective equipment; the prevalence rate of bronchial asthma was 3.0% for workers; and the variation rate of peak flow rate was -9.9% to 29.63% for workers before and after shift. Tip isocyanates can cause peak flow rate decreased, causing a small number of workers suffering from bronchial asthma.
