最近新闻上有军团菌的报道, 许多设施管理人员担心他们的医院是否会爆发疫情. 它可以. 的 following environments in 医疗保健 facilities offer the ideal environment for Legionella growth:
这些设置的热和半不活跃状态, 结合它们的雾化机制(射流), 喷雾, 和迷雾), 使病人有可能吸入或抽吸被污染的水滴. 虽然健康的人也会感染这种疾病, 免疫系统受损的住院病人最容易受到感染.
环境温度超过68华氏度的水系统易受军团菌生长的影响. 长时间低流量或不使用的系统也是如此. 热清除将水温加热到124华氏度以上以抑制细菌生长. 但是，皮肤在110华氏度的高温下会烫伤，在140华氏度的高温下会烧伤. Mixing valves at outlets prevent injuries by reducing the water temperature below 110°F just before it exits the system. 绝缘, 自动排水, 再循环循环分配系统进一步调节水温.
军团菌在死水中生长. 的 工程 controls that maintain temperatures also must have the ability to regulate water flow. Knowing if your controls are capable of maintaining flow is difficult as the components that regulate flow are seldom visible. 然而，在翻新过程中，储罐和死腿管道是常见的罪魁祸首. 防止停滞, 水泵应该连续运行，并与节能计划分开.
并不能保证任何水处理方法都能根除这种微生物. 相反，医院可以用杀菌剂或氯等氧化剂来防止军团菌的生长. 连续氯化, 美国大多数冷却塔都采用这种方法, 难道不是饮用水系统的一个选择吗. 医院必须通过降低温度的工程控制来处理饮用水系统.
你应该从哪里开始?? 一名水质工程师正在检测军团菌的存在, 管道工程师识别促进军团菌活动的基础设施要素.
Plumbing engineers begin by performing an as-built survey to identify possible Legionella growth sources. 然后，他们建议通过工程控制来阻止未来的细菌培养. 他们推荐的任何预防措施都应遵循最新指南:ASHRAE 188-2015.
