目的:测量紫外灯消毒辐射强度,判定是否符合消毒要求;查询紫外灯使用记录,测量消毒的辐射距离及消毒空间体积,判定消毒时间、距离及体积是否符合要求。方法:根据《紫外线杀菌灯(GB19258)》及《消毒技术规范》的相关标准和要求,2015年—2016年对某医疗机构21个实验室的紫外线灯管照射室内空间的体积(m3)、紫外线灯管的照射强度(μW/cm2)、使用时间、表面清洁情况、空间温湿度进行监测评价。结果:32盏紫外线灯中辐照强度大于70μW/cm2的有两盏,合格率6.25%;(70~40)μW/cm2的28盏;低于40μW/cm2的有两盏;15台生物安全柜(超净台)中,除麻疹实验室的一台生物安全柜中的紫外线照度略低(62μW/cm2),其余均达到紫外线灯杀菌规定。结论:紫外线消毒是空气、物体表面及消毒的一种简便、有效的方法,不同级别生物安全实验室要求不同,但仅靠紫外线灯维持实验室清洁度是不符合实验室要求的。为保证实验室样品之间不产生交叉感染,保证实验室人员自身安全,紫外线空气消毒是十分重要的,这样才能将实验的危险因素降到最低,最大程度的保证实验人员的安全。
OBJECTIVE: To measure the radiation intensity of UV lamp to determine whether it meets the requirement of disinfection; to check the record of UV lamp usage, to measure the radiation distance of disinfection and the volume of disinfection space, and to determine whether the disinfection time, distance and volume meet the requirements. Methods: According to the relevant standards and requirements of “UV germicidal lamp (GB19258)” and “disinfection technical specifications”, the volume of indoor space (m3) irradiated by ultraviolet lamps in 21 laboratories of a medical institution from 2015 to 2016, Lamp irradiation intensity (μW / cm2), the use of time, surface cleaning, space temperature and humidity monitoring and evaluation. Results: There were two of 32 UV lamps with an irradiance of more than 70μW / cm2 with a pass rate of 6.25%, 28 of 70 ~ 40 μW / cm2, two of less than 40μW / cm2 of biosafety In the cabinet (clean bench), the UV illumination in a biosafety cabinet except the measles laboratory is slightly lower (62 μW / cm2), and the rest of the rooms are UV disinfected. Conclusion: UV disinfection is a simple and effective method for air, surface and disinfection. Different levels of biosafety laboratories have different requirements. However, the maintenance of laboratory cleanliness by UV lamps is not in line with laboratory requirements. In order to ensure that laboratory samples do not produce cross-infection between samples to ensure their own safety laboratory staff, ultraviolet air disinfection is very important, so as to minimize the experimental risk factors, to the maximum extent possible to ensure the safety of laboratory personnel.
