In this study, the Municipality of Nakhon Chaisri, Nakhon Chaisri District, Nakhon Prathom Province where there are some residences in which the asbestos-containing materials such as roof tile, ceiling, and asbestos concrete tubes have an impact on the health. The field data was collected for experiment. In the experiment, the wet process demolition of asbestos materials was examined. Demolishing the asbestos materials was conducted in the water to avoid the dust particles diffusion. Granular dust measurement device was used. The results showed that the wet process demolition of asbestos materials in three types of asbestos-containing materials and in three different sizes of the dust particles; 2.5 μm, 3 μm, and 5μm pre-experimentally and postexperimentally showed the different values ±10, indicating that wet process demolition of asbestos materials caused no dust particle diffusion. In addition, in the collaboration with the government agencies (Nakhon Chaisri Municipality), it instructs the public the hazards of asbestos and wet process demolition of asbestos materials.
