目的比较分析国际采矿与金属委员会与罗马尼亚劳动和社会保障部(ICMM与MLSP)的2种风险评估方法在耐火材料生产企业尘肺病风险评估中的适用性,探索适合耐火材料生产企业尘肺病风险评估的模型。方法随机选取23家耐火材料生产企业为研究对象,重点调查破碎、配料、混料、成型4个岗位,采集粉尘浓度数据,并进行2种风险评估。结果 4个重点岗位总尘(呼尘)超标率分别为100%(100%)、100%(100%)、83.33%(100%)、77.78%(77.78%)。4个重点岗位Ⅲ期矽肺风险用ICMM定量法判定为不可容忍,ICMM矩阵法判定为高风险,MLSP法判定为高风险。尘肺病风险评估结果得到现场检测结果、粉尘作业分级结果以及相关文献报道的验证。结论考虑到管控从严、避免主观偏倚等原因,ICMM风险评估方法在耐火材料生产企业尘肺病风险评估上有一定的优势。
Objective To compare and analyze the applicability of two risk assessment methods jointly developed by the International Council on Mining and Metals and the Ministry of Labor and Social Security of Romania (ICMM and MLSP) in the risk assessment of pneumoconiosis in refractories manufacturing enterprises and to explore a suitable pneumoconiosis risk assessment for refractory manufacturing enterprises Model. Methods Twenty-three refractory production enterprises were randomly selected as the research objects. Four positions including crushing, compounding, mixing and forming were surveyed. The dust concentration data were collected and two kinds of risk assessment were conducted. Results The exceeding rates of total dust (dust) in four key positions were 100%, 100%, 83.33% and 77.78%, respectively. The risk of stage III silicosis in 4 key positions was judged as unacceptable by the ICMM quantitative method, the ICMM matrix method was judged as high risk, and the MLSP method was judged as high risk. Pneumoconiosis risk assessment results are field test results, dust classification results and related reports verified. Conclusions Due to strict control and avoiding subjective bias, the ICMM risk assessment method has certain advantages in the risk assessment of pneumoconiosis in refractory manufacturing enterprises.
