目的了解N-甲基甲酰胺生产过程中存在的职业病危害因素及危害程度,提出职业病防治的重点。方法对某化工企业新建10万吨N-甲基甲酰胺项目进行职业病危害因素调查。结果项目在生产过程中存在的职业病危害因素有甲酸甲酯、氨、一氧化碳、一甲胺、二甲胺、三甲胺、甲醇、N-甲基甲酰胺、噪声。除少部分作业点噪声强度不符合国家卫生标准外,大部分作业点空气中化学毒物浓度和噪声符合国家卫生标准。结论该项目职业病危害因素的防护措施基本可行、有效。今后进一步加强对职业病危害因素的防治工作。
Objective To understand the occupational hazards and hazards in the production of N-methylformamide and to put emphasis on the prevention and control of occupational diseases. Methods Investigate the occupational hazards of a new chemical project of 100,000 tons of N-methyl formamide. Results The occupational hazards of the project include methyl formate, ammonia, carbon monoxide, monomethylamine, dimethylamine, trimethylamine, methanol, N-methyl formamide and noise. In addition to the noise intensity of some operating points is not in line with the national health standards, most of the chemical concentration and noise in the air in the operation point in line with national health standards. Conclusion The protective measures of occupational hazards in this project are basically feasible and effective. In the future to further strengthen the prevention and treatment of occupational hazards.
