目的对某工程制图单位职业病危害因素进行识别及分析,确定该工程制图单位的职业病危害程度,为采取合理的治理措施提供科学依据。方法采取现场职业卫生学调查及职业卫生检测方法,2014年每季度一次对该工程制图单位存在的职业危害因素进行检测,并在第四季度采用不同吸收液对该工程图纸制造单位工作场所中氨浓度进行检测,用对比列表法对结果进行探讨。结果该工程制图单位存在的主要职业危害因素为氨,第三季度的晒图机进纸口氨的浓度超出职业接触限值,其他季度及其他检测点的工作场所氨的浓度均符合职业接触限值要求。0.005mol/L硫酸溶液为吸收液时检测氨的浓度要高于蒸馏水为吸收液时的检测结果。结论该工程制图单位的工作场所氨浓度基本达到国家卫生标准。采用不同浓度吸收液在工作场所空气中氨的采集中吸收率不同,建议采用硫酸溶液进行工作场所空气中氨的采集,
Objective To identify and analyze the hazard factors of occupational diseases in a mapping unit of a project and determine the degree of occupational hazards of the cartographic units in this project so as to provide a scientific basis for taking reasonable control measures. Methods Occupational hygiene tests and occupational health tests were conducted in the field. In 2014, the occupational hazards of the engineering drawing unit were tested on a quarterly basis in 2014. In the fourth quarter, different absorbing solutions were used to measure ammonia Concentration test, the results of the comparison list method to explore. Results The main occupational hazards of the engineering drawing unit were ammonia. The concentration of ammonia in the paper inlet of the tanning machine in the third quarter exceeded the occupational exposure limit. The concentrations of ammonia in the workplace in other quarters and other testing sites all met the occupational exposure limits Claim. 0.005mol / L sulfuric acid solution for the detection of ammonia concentration when the absorbent is higher than the absorption of distilled water when the test results. Conclusion The ammonia concentration in the workplace of the engineering drawing unit has basically reached the national health standard. Different concentrations of absorbent liquid in the workplace, the absorption of ammonia in the air is different, the proposed use of sulfuric acid solution for workplace air ammonia collection,
