Asbestos Exposure Monitoring in Worker Demolished Asbestos Contained Material Building and the Concentration in Environment

ABSTRACT

This research come from the study of air sampling analysis and exposure of asbestos from the demolition of Building which contained asbestos material (such as ceiling and roof) by using both of personal and environment air samples. The result of fiber concentration of personal air sample attached to the ones who work with asbestos material (eg. remove ceiling and roof) and the environment air sample inside the building were 0.1-0.4 fiber/mL. which were higher or close to that of ACGIH standard, 0.1 fiber/mL., that showed the potential of risk to impair health of workers. Workers should change their methods to lower the blow out of asbestos and also wear the appropriate PPE. However, the asbestos fiber content in air sample of the atmosphere outside the building was found to be lower than that of ACGIH standard. From this result, it show that Thailand should do more research about the exposure of asbestos from demolition of old building to set proper control measures for safety of the workers.
