The site provides information to help employers control exposure to dust in the workplace, as well as providing further information on dust. Dust is tiny, dry particles in the air and can be produced when materials are cut, drilled, demolished, sanded shovelled etc and so many work activities can create dust. It is not an obvious health hazard but the health effects of exposure can take many years to develop.
