Popis

Using cut-off saws on paving blocks and kerbs can produce very high levels of silica-containing dust. Effective control is necessary because this work is high risk. This page provides information on how to control this risk and why it should be controlled. Uncontrolled cutting quickly produces very high levels of silica-containing dust, as is shown in a graph displayed in a video clip demonstrating how much silica is created when dry cutting. The graph shows a dramatic drop in the amount of silica-containing dust produced when using water suppression.
