半密闭式钛渣生产项目控制效果评价中噪声危害关键控制点分析

[目的]通过对两个半封闭式钛渣生产项目中噪声危害进行识别与分析,找出钛渣生产项目控制效果评价中的噪声危害关键控制点,并提出针对性预防措施。[方法]采用职业卫生现场调查、工程分析、工作场所噪声检测与职业健康检查的方法,对两个半封闭式钛渣生产项目中噪声危害进行识别、分析与检测,结合工程防护、个体防护及工人健康资料对现场噪声关键控制点进行分析。[结果]半封闭式钛渣生产项目中接噪岗位噪声强度超标率分别为80%和70%,超标岗位噪声的频谱分析主要以中高频为主;半封闭式钛渣生产项目中噪声关键控制点为配料、投料、冶炼、破碎、球磨、分筛、磁选、成品包装、电极破碎、除尘等岗位,占总接噪岗位的83.33%。[结论]目前半封闭式钛渣生产项目中接噪岗位较多,噪声超标情况较为严重,噪声的关键控制点较多,而该方面的研究报道较少。所以该研究为今后在对类似项目的职业病危害控制效果评价中,建议厂方对噪声危害的防护应从噪声危害的关键控制点着手提供依据,使工人实际接触的噪声声级控制在国家职业卫生限值以下。

ANALYSIS OF KEY CONTROL POINTS OF NOISE IN ASSESSMENTS ON EFFECT OF CONTROLLING OCCUPATIONAL HAZARD IN TWO SEMI-CLOSE TITANIUM SLAG CONSTRUCTION PROJECTS

[Objective]To investigate and analyze the key control point of noise hazard in the occupational hazard control assessments of two and provide the effectively preventive measures in the semi-close Titanium slag production projects.[Methods]Used occupational health investigation,analysis for engineering,measurement of noise in workplace and occupational health surveillance to distinguish,analyze and test the occupational noise hazards with the status of protective facility,personal protection and the data of ...
