On-site processing of spent fluorescent lamps reduces storage space requirements and prevents mercury-containing lamp contents from entering the municipal waste stream, but such processing activities are typically not carried out in facilities specifically designed for the operation. This circumstance is of particular concern because lamp-handling and -crushing operations can release mercury vapors and aerosols that constitute an occupational exposure risk. In the study reported here, sampling for airborne mercury was performed during the processing of fluorescent lamps in an enclosed work area and in an open, outdoor work environment. In both enclosed and open work environments, exposures in excess of the established mercury exposure limit were detected. Simple interventions to prevent this possible unanticipated source of mercury exposure are described.
废旧荧光灯的现场处理减少了存储空间需求，并防止含汞灯的内容物进入城市废物流，但此类处理活动通常不在专门设计用于该操作的设施中进行。这种情况尤其令人担忧，因为灯具处理和破碎操作会释放汞蒸气和气溶胶，构成职业暴露风险。在本文报道的研究中，在封闭工作区域和露天工作环境中对荧光灯进行处理期间，对空气中的汞进行了采样。在封闭和露天工作环境中，均检测到超过既定汞暴露限值的暴露情况。文中描述了防止这种可能意外的汞暴露源的简单干预措施。
