What is required for cutting machines on roofs regarding misting?

Misting cutting machines on roofs is essential for controlling airborne asbestos fibers during operations. Continuous misting plays a critical role in suppressing dust that could become airborne when cutting materials that contain asbestos. By maintaining a consistent level of mist, the water helps to encapsulate and settle dust particles, thereby reducing the risk of inhalation and exposure for workers.

This approach is particularly vital during renovation or demolition activities involving asbestos-containing materials, as the generation of dust can pose serious health risks. Continuous misting ensures that the work environment remains safer and compliant with safety regulations. The other options suggest less consistent or complete moisture application, which could increase dust levels, making the work area hazardous. Thus, continuous misting is the recommended best practice to minimize exposure and ensure worker safety.
