摘要
目的 比较3种风险评估方法对树脂锚固剂生产车间中化学有害因素职业健康风险评估的适用性。方法 采用判断抽样方法,选择某树脂锚固剂生产车间为研究对象,分别采用接触比值法、综合指数法(以上均为半定量评估法)和定性风险评估法对其涉及苯乙烯、邻苯二甲酸二丁酯、邻苯二甲酸酐的岗位进行职业健康风险评估。将评估结果标准化为风险比值后,对3种方法的评估结果进行比较。结果 对于各岗位的职业健康风险等级,接触比值评估法评估的结果为1~3级,综合指数法评估的结果为2~3级,以上方法标准化后的风险比值与标准化前的风险等级一致;定性风险评估法评估的结果为2~3级,标准化后的风险比值为3~4级,标准化后的风险比值均比标准化前的风险等级提高1级。Kappa分析结果显示:接触比值法与综合指数法一致性较好(Kappa=0.53,P<0.05);定性风险评估与接触比值评估、综合指数法的评估结果一致性差(Kappa值分别0.19、0.40,P值均<0.05)。结论 在能够获得职业病危害因素检测结果的情况下,综合指数法是针对锚固剂生产车间进行职业健康风险评估的首选方法;在无法获得检测结果时可采用定性风险评估法。
Objective To compare the applicability of three risk assessment methods on occupational health risk assessment of chemical harmful factors in a resin anchorage production workshop. Methods A resin anchoring agent production workshop was selected as the research subject using the judgment sampling method. Contact ratio assessment method and comprehensive index method(both are semi-quantitative evaluation method) and qualitative risk assessment method were applied to estimate the occupational health risks of jobs involved with styrene, dibutyl phthalate and phthalic anhydride. The assessment was carried out, and the obtained risk level was standardized as the risk ratio. The evaluation results of these three methods were compared. Results The assessment results of exposure ratio method were 1-3, and those of comprehensive index method were 2-3. The risk ratio of the above methods after standardization is consistent with that before standardization. The result of qualitative risk assessment was 2-3, and the risk ratio after standardization was 3-4. The risk ratio after standardization was 1 level higher than that before standardization. Kappa analysis results showed that the result of contact ratio method and the comprehensive index method was in good agreement(Kappa=0.53, P<0.05). The qualitative risk assessment method was inconsistent with the contact ratio method and the comprehensive index method(Kappa values were 0.19 and 0.40, both P<0.05). Conclusion Comprehensive index method is the preferred method for occupational health risk assessment of anchorage agent production workshop under the condition that detection results of occupational hazards can be obtained. Qualitative risk assessment method can be used when the test results cannot be obtained.
