Dry sweeping concrete dust and other building debris can produce high levels of dust. Avoid dry sweeping where possible because this can be high risk. This page provides information on how to control this risk and why it needs to be controlled. Clearing up may seem low risk. However, dry sweeping can push large amounts of dust into the air. The graph displayed in the video available on the page shows how much silica is created when dry sweeping concrete dust. The graph shows a dramatic drop in the amount of silica-containing dust produced when using the correct extraction unit. By using such an extraction unit, the dust is quickly removed and there is no resettling later.
