This site provides information to help employers control exposure to dust in the workplace. You can also access further information on dust from this site.
Dust is tiny, dry particles in the air and can be produced when materials are cut, drilled, demolished, sanded, shovelled, etc. This means many work activities can create dust. Dust is not always an obvious health hazard as the particles which cause the most damage are often invisible to the naked eye and the health effects of exposure can take many years to develop.
