Assessing occupational mercury exposures during the on-site processing of spent fluorescent lamps.
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.
