目的对某新建焦化厂生产过程中可能产生的主要职业病危害因素进行识别、分析和评价。方法依据国家相关标准,对该建设项目的类比对象进行现场调查及检测,采用系统分析法、类比法和检查表法进行定性、定量评价。结果经类比调查检测生产过程中产生的主要职业病危害因素STEL(mg/m3)为:CO未检出~30.1、CO2157~550、SO22.04~3.01、硫化氢<0.53、氨0.13~7.82、苯0.60~2.40、硫酸0.46、氢氧化钠<0.05、煤尘;噪声65.4~94.1 dB(A),合格率为92.3%。结论本项目为职业病危害严重的建设项目。只要在后续的施工、生产过程中认真按设计要求进行,并采纳预评价报告中提出的补充建议,预计工程建成后能符合国家规定的职业卫生要求。
Objective To identify, analyze and evaluate the major occupational hazards that may occur during the production of a new coking plant. Methods Based on the relevant national standards, on-site investigation and testing of analog objects of the construction project were carried out. The methods of system analysis, analogy and checklist were used for qualitative and quantitative evaluation. Results STEL (mg / m3) was the main risk factor for occupational diseases detected in the production process by analogy investigation: CO undetected ~ 30.1, CO2157 ~ 550, SO22.04 ~ 3.01, H2S <0.53, ammonia 0.13 ~ 7.82, benzene 0.60 ~ 2.40, sulfuric acid 0.46, sodium hydroxide <0.05, coal dust; noise 65.4 ~ 94.1 dB (A), pass rate of 92.3%. Conclusion This project is a serious construction project with serious occupational diseases. As long as the follow-up construction and production processes are carried out according to the design requirements carefully and the supplementary suggestions made in the pre-evaluation report are adopted, the project is expected to meet the occupational health requirements stipulated by the state upon completion.
