Guideline for Managing Impacts of Dust
www.der.wa.gov.auDust is an aerosol formed by mechanical subdivision of bulk material into airborne fines having the same chemical composition. Dust particles are generally solid and irregular in shape and have diameters greater than one micrometre. A fume is an aerosol of solid particles formed by condensation of vapours formed at elevated temperatures.

www.hse.gov.ukVisible dust on pipes, surfaces, ledges etc may indicate the presence of airborne dust. However, many dust particles are too fine to be visible under normal lighting conditions. A dust lamp, which provides a powerful beam of light, can be used as a quick method to show whether a fine dust is present, and helps to pinpoint the

High-energy tools like cut-off saws, grinders and grit blasters produce a lot of dust in a very short time; work area – the more enclosed a space, the more the dust will build up. However, do not assume that

www.who.intFurthermore, dust particles are frequently found with dimensions considerably <1 µ m and, for these, settling due to gravity is negligible for all practical purposes. The terminal velocity of a 1-µm particle is about 0.03 mm/sec, so movement with the air is more important than sedimentation through it. Therefore, summarizing in the
