Many construction tasks create dust. High dust levels are caused by one of more the following:
Equipment – using high energy tools, such as cut-off saws, grinders, wall chasers and grit blasters produce a lot of dust in a very short time.
Work method – dry sweeping can make a lot of dust when compared to vacuuming or wet brushing
Work area – the more enclosed a space, the more the dust will build up
Time – the longer you work the more dust there will be
Examples of high dust level tasks include:
Using power tools to cut, grind, drill or prepare a surface
Sanding taped plaster board joints
Dry sweeping
