컨테이너 하역 작업자의 유해화학물질 노출 위험도 분석

초록

Containers usually are used as the general oversea transportation facilities in global. The fumigation materials such as Methyl bromides and formaldehyde, which would be known to be toxic to human or anima beings, commonly are used to remove harmful insect inner containers. Also, workers in unloading container would be easily exposed to toxic materials at working sites and have been reported to occur the safety accidents which would cause many health and damages of workers. In this study, the experimental analysis would be conducted for container unloading workers' exposure risk to hazardous chemical materials based on the international standard, and the kinds and emitted concentrations of hazardous materials would be analyzed and judged occupational exposed risk for electronics products. The results of this study showed that the fumigation materials would be found for all containers. In some containers, it was showed that formaldehyde was found and over occupational exposure limits(OELs) and showed to be found toluene in low level under OELs. But, the inner containers' formaldehyde and toluene detected in tube test would be founded under OELs in precision analysis, and then worker's exposure risk showed that it could be very lower. In case of products and packing materials, the concentration of formaldehyde and VOCs(Bezene, Toluene) could be under OELs, and then the worker's exposure risk showed it could be lower. In the future, it should be set up management procedure to prevent worker in handling containers of domestic, and it will be applicable to analyze worker exposure risk for another industrial products. except of electronics.
