To address the issue of degrading air quality due to the demolition of wooden boards, the most direct and effective initial step would be to use saws equipped with dust guards or collectors. These devices help to capture and contain sawdust at the source, preventing it from becoming airborne and contaminating the indoor environment. This approach aligns with best practices in occupational health and safety, as it directly addresses the source of the pollution and minimizes the exposure of workers and other occupants to potentially harmful airborne particles.
