Sep 28, 2010· Respirable Silica Dust in Mining • Dust less than 10 microns in size (cannot be seen with the eye) • Overexposure can cause lung disease • Xray surveillance may be initial means of disease diagnosis • Current dust exposures limits established in 1977 • Occupational sampling conducted by MSHA to monitor exposure
When a sufficiently hard abrasive particle strikes steel, it deforms the surface into a valley and pushes up peaks. The distance between the top of the peak and the bottom of the valley is known as the depth profile. In the, the depth profile is measured by mils – thouhs of an the metric system, the micron(one millionth of a meter) is used.

Feb 23, 2012· Government standards for HEPA filters for silica dusts say it must remove % of particles greater than micrometer from the air. The fliter that comes with that unit appears to stop nothing below 1 micron. It is the sub micron particles that are of REAL concern.
Nov 06, 2000· How much silicosis people will develop depends on genetics and degree of exposure to respirable quartz, which is silica dust ranging from .2 or .3 microns in diameter to 5 microns, says Levin. Particles larger than this are trapped in upper airways and smaller particles are largely blown out because they act like a gas, he says.
