【摘要】：為科學(xué)合理地進(jìn)行建設(shè)項目職業(yè)病危害風(fēng)險分類,基于系統(tǒng)工程及風(fēng)險評估的基本原理,采用Delphi法分析和確定了影響職業(yè)病危害風(fēng)險程度的因素,通過構(gòu)建風(fēng)險評估指標(biāo)體系,建立了職業(yè)病危害影響因子賦值法(OHFA)定量化風(fēng)險評估模型。根據(jù)對作業(yè)場所的危害源、本質(zhì)及附加防護(hù)設(shè)施水平、人員接觸機(jī)會、職業(yè)病防治管理等因子的綜合分析,預(yù)測分析了研究對象的職業(yè)病危害的風(fēng)險程度,為職業(yè)病危害風(fēng)險辨識、風(fēng)險評估、防治管理及防護(hù)設(shè)施設(shè)計等提供參考。并以某石化行業(yè)硫磺回收項目為實例進(jìn)行應(yīng)用與驗證,得出了該項目的總體職業(yè)病危害風(fēng)險度值為12,風(fēng)險等級為Ⅰ級,各職業(yè)病危害因素的風(fēng)險度由高到底排序為硫化氫、一氧化碳、二氧化硫、硫磺、高溫,其風(fēng)險分類的關(guān)鍵決定因素為硫化氫。實踐表明該方法與專家評估結(jié)果及工程實際吻合較好,應(yīng)用于職業(yè)病危害風(fēng)險評估中可給出定量化的風(fēng)險分類結(jié)果。
[Abstract]:In order to classify the occupational hazard risk of construction project scientifically and reasonably, based on the basic principles of system engineering and risk assessment, the factors influencing the risk degree of occupational disease hazard are analyzed and determined by Delphi method, and the risk assessment index system is constructed. A quantitative risk assessment model of occupational disease hazard factor assignment method (OHFA) was established. Based on the comprehensive analysis of the hazard source, nature and level of additional protective facilities, personnel contact opportunities, occupational disease prevention and control management and other factors in the workplace, the risk degree of occupational disease hazards was predicted and analyzed. It provides reference for occupational hazard risk identification, risk assessment, prevention and control management and design of protective facilities. Taking the sulfur recovery project of a petrochemical industry as an example, the results show that the overall occupational hazard risk degree of the project is 12, the risk grade is grade 鈪，
