Verification of the Dispersion of Asbestos Fibers During Cutting and Removing of Asbestos-Containing Building Materials

Key Points

This research investigates the concentration of asbestos fibers released during cutting and evaluates dust suppression measures.
Performed cutting tests in a controlled environment using asbestos-containing materials, including coating, slate boards, and calcium silicate boards.
Measured the release level of asbestos fibers and compared it with previous studies.
Demonstrated significant levels of asbestos fiber dispersion during cutting processes.
Validated the effectiveness of dust suppression measures in reducing fiber release.

Abstract

The purpose of this study was to verify the concentration of asbestos and other fibers generated during cutting and related work with power tools, and to evaluate the effectiveness of dust suppression measures. The research also aimed to provide insights for safer renovation and demolition practices to prevent asbestos exposure. Experiments, including cutting tests, were conducted in an isolated curing area using asbestos-containing finishing coating materials, slate boards, and type 1 calcium silicate boards. The level of asbestos fiber release was measured and compared with findings from previous studies.
