二异氰酸甲苯酯(TDI)常作为一种聚合剂用于聚氨酯类泡沫生产。接触TDI可引起眼、鼻、喉的刺激症状,有时可致典型的支气管哮喘。由美国国家工业卫生学家协会(ACGIH)制定的TDI阈限值(TLI)为0.02ppm。 本次调查场所选择在一艘液化石油船的底舱,用聚氨酯泡沫绝缘材料铺于舱的底板上。作者对工人所在的几个主要的工作场所空气中TDI浓度作了测定,并以39名接触TDI的男工为检查对象,同厂10名男性职员为对照,分别进行了血清IgE、肺功能等项测定。另外,还通过询问表方式回顾了解有关呼吸道的主观症状、过敏性疾病史、吸烟史及工作经历。
Toluene diisocyanate (TDI) is often used as a polymerization agent for polyurethane foam production. Exposure to TDI can cause eye, nose, throat irritation, and sometimes can cause typical bronchial asthma. The TDI Threshold Limit (TLI) established by the National Institute of Industrial Hygienists (ACGIH) is 0.02 ppm. The survey site is selected in the bottom of a liquefied petroleum tanker, with polyurethane foam insulation paved on the tank floor. The authors measured the concentration of TDI in the air at several major workplaces where the workers were located. Totally, 39 male workers who were exposed to TDI were selected as the test subjects and compared with 10 male workers in the factory. Serum IgE, pulmonary function, etc. Item determination. In addition, also through the questionnaire to review the way to find out about the subjective symptoms of the respiratory tract, history of allergic diseases, smoking history and work experience.
