석면함유 천장재의 비산방지제 성능 평가 연구

Abstract

In compliance with the Ministry of Environment’s Asbestos Safety Management Act (enforced on 4. 28. 2012), the building owners are required to carry out asbestos building survey. Depending on the results of the surveys, the owners of such buildings need to implement necessary measures such as repairs, sealing, or closure of the relevant areas. In this study, a test for asbestos scattering limit on asbestos head lining and scattering tests before and after applying a scattering inhibitor on a subject target were implemented. The result of the asbestos scattering limit test confirmed the possibility of asbestos scattering on both the front and back side of the interior material. Tests regarding the efficiency of the scattering inhibitor showed that in the absence of the scattering inhibitor, the detected asbestos concentration exceeded the limit prescribed as per the indoor air quality guidelines; however, with the application of two types of scattering inhibitors, the asbestos concentration in the indoor air was less than the prescribed limit. These results confirmed that the asbestos scattering inhibitor is effective in suppressing the spattering of asbestos; however, it will be necessary to have regulatory controls such as the obligatory use of scattering inhibitor after development of which can prevent all asbestos scattering inhibitor. The results of this study are expected to be utilized as base data for both the maintenance and development of various management programs aimed at an effective maintenance of asbestos building material.
