The Characteristics of Asbestos Distribution in Some Public an School Buildings
Abstract
This study was performed to investigate the characteristics of asbestos distribution in 6 public and 6school buildings from August to September in 2006. The bulk samples were analysed by PLM(polarized lightmicroscope). Also the airborne samples were analysed PCM(phase contrast microscope) and confirmed bySEM-EDX(scanning electron microscope-energy dispersive using X-ray analysis) method. The 6 publicbuildings included the ACM(asbestos containing material) ranged 2-7 % of chrysotile in 70 % of samplesfrom ceiling, floor tile, and wall board and has 20 % tremolite in 2 ceiling plaster. The 6 school buildingswere identified 1.5 % tremolite in one sample and showed the similar asbestos distribution with the publicbuilding. The airborne concentrations of fiber materials were ranged with 0.000-0.017 f/cc in public placesand 0.000-0.012 f/cc in school building by PCM. However, the asbestos fibers could not be found bySEM-EDX. In the result of physical assessment of ACM in each buildings, it is considered that there is nochance of a hazardous situation because the ACM is not friable. Its suggested that the asbestos control planshould be established to prevent asbestos exposure to occupants from damaged ACM by repairing andcustodial work.
