目的对某大型超市集中空调通风系统进行竣工验收预防性卫生学评价。方法通过现场调查、卫生检测等,结合委托单位提供的技术资料,采用风险评估法进行综合评价。结果该项目平面布局基本合理;设备布局和卫生管理方面存在卫生安全隐患;卫生检测结果显示:送风中微生物(细菌总数最高值510 cfu/m3、真菌总数最高值3 900 cfu/m3)和风管内表面微生物(真菌总数最高值120 cfu/cm2)超标,其他指标符合相关规范要求。结论该项目对设备布局、卫生管理和卫生状况进行整改后,经再确认方可运行。
Objective To evaluate the preventive sanitation of completed air-conditioning ventilation system in a large supermarket. Methods Through on-the-spot investigation, health inspection and so on, combined with the technical data provided by the entrusting unit, the method of risk assessment was used for comprehensive evaluation. Results The layout of the project was basically reasonable. There were health and safety risks in terms of equipment layout and health management. The results of health examination showed that the airborne microorganisms (the highest number of bacteria was 510 cfu / m3, the highest number of fungi was 3900 cfu / m3) Surface microorganisms (the maximum total number of fungi 120 cfu / cm2) exceeded the other indicators in line with relevant norms. Conclusion The project will be reconfirmed to rectify the layout of equipment, sanitation management and sanitation.
