【摘要】：目的探索新加坡化学物质职业暴露半定量风险评估技术的适用性。方法应用新加坡化学物质职业暴露半定量风险评估模型对2家小型木质家具企业开展职业健康风险评估,并将评估结果与我国现行的职业接触限值和作业分级结果进行比较。结果 2家企业主要生产工艺和岗位设置相近,主要职业病危害因素一致,现场均存在木粉尘超标,时间加权平均浓度(concentration of the time weighted average,CTWA)最高为29.42mg/m~3。用实际浓度计算暴露等级和用暴露指数计算的暴露等级获得的风险评估结果从低风险、中等风险、高风险到极高风险不等,且两种方法对同一岗位同一毒物的风险评估结果不一致,后者风险等级较高。结论应用半定量风险评估技术能预测和评估职业健康风险,但仍需开展更多的适用性研究来制定我国职业健康风险评估模型。
[Abstract]:Objective to explore the applicability of semi-quantitative risk assessment technique for occupational exposure to chemical substances in Singapore. Methods Occupational health of two small wooden furniture enterprises was carried out by using the semi-quantitative risk assessment model of chemical occupational exposure in Singapore. Risk assessment. The evaluation results were compared with the current occupational exposure limits and job classification in China. Results the main production processes and post settings of the two enterprises were similar and the main occupational disease hazards were the same. Wood dust was in excess of the standard, and the concentration of the time weighted average was measured by time-weighted average concentration. CTWAs are up to 29.42 mg / mc3.The risk assessment results obtained from the actual concentrations and the exposure levels calculated with the exposure index are from low risk to medium risk. The risk range from high to very high, and the results of two methods for the same toxic risk assessment in the same position are not consistent. Conclusion the semi-quantitative risk assessment technique can predict and evaluate occupational health risk, but more applicability research is needed to establish the occupational health risk assessment model in China.

【正文快照】： 风险评估[1](risk assessment)是指量化测评某一事件或事物带来的影响或损失的可能程度,客观地认识事物(系统)存在的风险因素,通过辨识和分析这些因素,判断危害发生的可能性及其严重程度,从而采取合适的措施降低风险概率的过程。职业健康风险评估是在识别和描述职业病危害因素
