A Study of Asbestos Containing Materials use and Risk Assessment methods in Community Service Centers (CSC)

Abstract

The aim of this study is to identify the characteristics of asbestos containing materials and risk assessment in Community Service Centes. We investigated 133 CSCs between January and December in 2009. We collected presumed asbestos containing materials according to EPA AHERA, and analyzed it by US EPA method 600/R/116. The airborne samples of CSCs were analyzed by Phase Contrast Microscopy. For the survey on ACM risk assessment, we sed both ASTM rule and Korea ACM risk assessment by the Korea ministry of employment and labor. The results were as follows. Detection rate of the ACM in CSCs showed that before 1970’s, 1970’s, 1980’s, 1990’s, 2000’s buildings were 40%, 100%, 85.7%, 92.3% and 46.4%, respectively. The miscellaneous materials showed that a high detection rate were gasket (100%), wall cement flat board (96.2%) and ceiling textile (74.9%). Ceiling textiles contained chrysolite/amosite (1 and 6%) and cement flat boards contained chrysolite (6 and 15%), gasket contained chrysolite (5 and 40%). The airborne concentration of fiber materials were ranged with 0.003~0.004 f/cc in CSCs by PCM. In this study, ASTM rule of asbestos material showed that 2 materials were “Abatement” grade and 309 materials were “Q&M” grade. And, adjusted Korea ACM risk assessment showed that 36 materials were “Fair” and 278 materials were “Good”. Study results can be used for data of asbestos use and management plane at Community Service Centers.
