Abstract
|
|
|
The study was performed at lead & zinc-plating steel plates process in steel factory from December, 1993 to July, 1994. The major objective were to evaluate exposure to lead and the performance of Local Exhaust Ventilation(L.E.V) Systems after
engineering improvement for workplace management. The airborne concentrations f inorganic lead dusts and fumes were measured before and after engineering improvement of L.E.V. Systems. And the efficiency of L.E.V. Systems were also evaluated.
@ES The results were as follows:
@EN Before engineering improvement, the airborne lead concentrations of personal and area samples were exceeded the Korean Threshold Limit Values, 0.05mg/㎥. However, it was founded that exposures to lead were controlled to lower than the Korean
TLVs.
Also, the overall performance of L.E.V. Systems was improved about 150% after engineering improvement.
