This means there is nothing specifically toxic about it, BUT any dust that is fine enough to reach the alveoli of the lungs causes damage, and the body has a very hard time expelling it. Serious lung disease can result from continued exposure. Asad AliDec 28, 2018 · Here are some best practices for dust management. 1. Capture the Dust at Its Source. Any effective dust control program should capture as much dust as possible and capture it at the source. This generally involves moving airborne dust particles into a hood or machine connection point, through a duct system, and then to the dust collector. The sponge is there to prevent glass dust going into the air, by supplying water so it catches the glass particles. The sponge touching the bit is also in contact with the water reservoir below to consistently deliver water against your grinder and glass piece.Too much dust (in house) Dust is considered an environmental contaminant. Dust particles range in size from 1 µm up to about 500 µm. Approximately 60% of dust particles come from the outside homes through vents, windows, doors and contaminated clothing and other items brought home.Too much dust (in house) Dust is considered an environmental contaminant. Dust particles range in size from 1 µm up to about 500 µm. Approximately 60% of dust particles come from the outside homes through vents, windows, doors and contaminated clothing and other items brought home.Thinner and shorter particles can't travel far enough to get to the lungs. So the thinner, shorter glass fibers (less than 2 μm in diameter, and even some up to 4 μm) tend to stay in the upper respiratory tract and be exhaled out. However, if the particles are longer, they can get to the alveolar regions and become toxic (15 μm or longer).It seems harmless, but moon dust can actually damage scientific equipment and be harmful to human health: It is like a sticky powder made from shards of glass. Neil Armstrong first stepped onto the moon 50 years ago, and his footprints in lunar soil will be there for million of years, according to NASA. There is no wind to blow the footprints away.
