摘要
目的 了解河南省托幼机构紫外线灯消毒状况,为紫外线灯的消毒质量控制提供依据.方法 于2021-2023年对河南省18个城市256所次托幼机构进行调查,通过现场问卷收集托幼机构紫外线灯的管理和使用数据,并使用紫外线辐射照度计测量紫外线灯的辐照强度.结果 256所次托幼机构均配备有紫外线灯,教室是安装紫外线灯的主要场所(93.44％);消毒主要针对空气(98.05％)和物体表面(81.25％).调查的161所次托幼机构中,85所次(52.80％)在采购紫外线灯时索要了产品合格凭证.256所次托幼机构中,143所次(55.86％)定期接受消毒工作督导,119所次(46.48％)定期开展辐照强度监测.共检测紫外线灯1 693支,辐照强度总合格率68.16％,合格率从2021年的53.02％(447/843)上升到2023年的84.36％(588/697),呈逐年升高趋势(x2趋势=174.42,P＜0.05);539支灯管不合格,其中辐照强度为0 μW/cm2的灯管189支,占不合格总数的35.06％.结论 河南省托幼机构虽然普遍使用紫外灯,但消毒效果仍存在管理不到位、辐照强度不合格等问题,应加强监测与使用管理,以确保紫外线灯消毒的效果.
Abstract
Objective To assess the disinfection status of ultraviolet(UV)lamps in kindergartens across Henan Province,so as to provide a basis for UV disinfection quality control.Methods A survey was conducted from 2021 to 2023 in 256 kindergartens in 18 cities within Henan Province.Data on the management and usage of UV lamps were collected via on-site questionnaires.The irradiation intensity of UV lamps was measured using a UV irradiance meter.Results All 256 kindergartens surveyed were equipped with UV lamps,with the classrooms bring the primry locations for installation(93.44％).Disinfection primarily targeted air(98.05％)and surfaces(81.25％).Of the 161 kindergartens surveyed,85(52.80％)requested qualification certificates during UV lamp procurement.Among the 256 kindergartens surveyed,regular supervision was reported by 143(55.86％)of the kindergartens,while 119(46.48％)conducted routine irradiation intensity monitoring.A total of 1 693 UV lamps were inspected,with an overall irradiation intensity qualification rate of 68.16％.The qualified rate showed upward trend from 53.02％(447/843)in 2021,to 84.36％(588/697)in 2023(x2 trend=174.42,P＜0.05).Among the 539 unqualified UV lamps,189 had an irradiation intensity of 0 μW/cm2,accounting for 35.06％of the total unqualified lamps.Conclusions Despite the widespread use of UV lamps,there are still significant issues with their disinfection effectiveness in the kindergartens of Henan Province,including inadequate management and unqualified irradiation intensity.There is an urgent need to strengthen monitoring and usage management to ensure the efficacy of UV disinfection.
