摘要
目的推动中水项目职业病危害预评价的开展,完善中水项目职业危害控制。方法用描述性流行病学方法,汇总分析4年间中水建设项目职业病危害预评价结果中需要改进的问题。结果中水建设项目选址、总体布局和设备布局3项指标合格率最高(83%～92%),3项指标间差异无统计学意义(χ2≤2.1919,P>0.05);评价指标中合格率中等的照明、通风和防护设施3项指标间差异无统计学意义(χ2≤2.8649,P>0.05);合格率最低的个人防护用品、警示标识、应急救援措施、职业卫生管理4项指标间差异无统计学意义(χ2≤2.0784,P>0.05);合格率较高的3项指标与合格率中等的3项指标间两两比较,差异有统计学意义(χ2≥32.1479,P<0.05);合格率中等的3项指标与合格率最低的4项指标间两两比较,差异有统计学意义(χ2≥7.6680,P<0.05)。结论中水建设项目职业病危害预评价工作需要加强并逐步完善。
[Objective] To promote the implementation of pre-assessment of occupational hazards in the reclaimed water project,improve the control of occupational hazards in the reclaimed water project.[Methods]With method of descriptive epidemiology,the problems which should be improved in results of pre-assessment of occupational hazards in the reclaimed water construction project in 4 years were summarized and analyzed.[Results]The qualified rates of location,general layout and equipment layout of reclaimed water construction project were the highest （83%~92%）,and there was no significant difference among three indexes （χ2≤2.191 9,P0.05）.The qualified rate of lighting,ventilation and protective facilities ranked the middle level,and their difference was not significant （χ2 ≤ 2.864 9,P 0.05）.The qualified rates of personal protective equipment,warning signs,emergency rescue measures and occupational health management were the lowest,and their difference was not significant （χ2≤2.078 4,P0.05）.There were significant differences between three indexes with higher qualified rate and three indexes with middle qualified rate （χ2≥32.147 9,P0.05）.There were significant differences between three indexes with middle qualified rate and four indexes with lower qualified rate （χ2 ≥ 7.668 0,P0.05）.[Conclusion]The pre-assessment of occupational hazards in the reclaimed water construction project should be strengthened and perfected.
