作业区环境对现场操作室内工业卫生指标影响的探讨

Probe into Effect of Operation Area Environment on Industrial Hygiene of Local Operation Room

针对化肥厂作业区个别现场操作岗位作业环境条件较差，噪声、尘、毒超标，操作室内通风采光不理想这一现象；我们分别选择两组尘、毒、噪声、高温发生源的车间、岗位分别进行作业环境监测。甲组具有自然通风和机械通风设施，乙组无自然通风和机械通风设施；测定结果表明，通风采光的好坏对现场操作室内空气的温度、相对湿度、照明度以及尘毒浓度有明显影响；

The operation environment of a few local operation stations is poorer in operation areas of fertilizer plant, in which all of their noise, dust, toxic substance can′t be reached to standard indexes, and aeration and lighting aren′t good neither Therefore, two groups of workshop and station with noise, dust, toxic substance and high temperature resources are chosen separately to make inspection of operation environment First group has natural and mechanical aeration facilities, and second group hasn′t Their inspection results showed that situation of aeration and lighting will obviously affect air temperature, relative humidity, intensity of illumination and concentration of dust and toxic substance, but it has a little effect on nois only
