ABSTRACT
Occupational exposure to lead among fire assay workers in quality control laboratory normally
impact greater to workers who actively contact with lead in metal analysis processes including
activities like chemical preparation and fire assay process. Based on the measurement result of
Pb concentration, the mean exposure to Pb in fire assay laboratory workers is 0.04 mg/m
3, with
the average personal intake of lead is obtained at 0.018 mg/m
3. Threshold limit values (TLV) for
chemical factor in workplace based on Ministry of Manpower and Transmigration of Republic of
Indonesia Regulation Number PER.13/MEN/X/2011 about of 0.05 mg/m
3, and thus the results
of this research is still below the stated threshold limit value. Cumulatively, fire assay workers are
still in the range of the reference interval 0 μg/dl to 14 μg/dl, although there is a gradual increase
in PbB concentrations counted from 2012 until 2015. Regular maintenance of the ventilation
system, monitoring the health of workers, job rotation and compliance to work safety procedures
are among others very important in the effort and action to prevent and reduce their exposure.
