某高校教学与科研实验场所职业危害因素调查

Investigation on occupational hazard factors in teaching and research places of a university

目的对某高校教学与科研实验场所(以下简称场所)职业病危害因素进行调查与监测, 为高校职业卫生防治工作提供依据。方法于2014年11月, 采用分层随机抽样, 对某高校46处场所存在的职业病危害因素进行现场职业卫生调查检测并对数据进行统计分析。结果 21处场所检测了室内气温、湿度、二氧化硫、二氧化氮、一氧化碳、二氧化碳, 6处场所检测了二甲苯、氢氟酸浓度, 18处场所检测了菌落总数, 23处场所测量了工频电场强度, 4处场所测量了X线辐射剂量, 检测结果均合格。噪声测量21处场所, 7处超标占33.3%(7/21);照度测量21处场所, 10处不合格占47.6%(10/21);微波辐射测量10处, 3处超标占30%(3/10);室内新风量、风速测量25处, 18处不合格占72%(18/25), 其中风速在教学、科研、实验场所差异有统计学意义(P=0.010)。结论高校教学科研场所中存在职业病危害因素应予以关注, 建议加强实验过程中的工程防护和个体防护。

Objective To investigate and monitor the occupational hazards in the Teaching and Research Laboratory(hereinafter referred to as the place)of a university,so as to provide basis for the occupational health work in the university.Methods November 2014,46 places in a university were selected by stratified random sampling,and the occupational health risk factors were investigated.Results Indoor temperature,humidity,sulfur dioxide,nitrogen dioxide,carbon monoxide and carbon dioxide were detected in 21 sites,xylene and hydrofluoric acid were detected in 6 sites,and colony count was detected in 18 sites,the power frequency electric field intensity was measured in 23 places,and the x-ray radiation dose was measured in 4 places.Noise was measured at 21 sites,with 7 sites exceeding the standards accounting for 33.3%(7/21);21 sites were detected for illumination and 10 sites for nonconformity accounting for 47.6%(10/21);10 sites for Microwave Radiation and 3 sites exceeding the standards accounting for 30%(3/10);and 25 sites were detected for outdoor air volume and air velocity,the percentage of unqualified was 72%(18/25)in 18 sites,among which the wind velocity was statistically significant in teaching,research and experimental sites(P=0.010).Conclusion The occupational hazards in the teaching and research places of a university should be paid attention to,and the engineering protection and personal protection should be strengthened in the experiment.
