drivers, crusher operators, front-end loader operators, and rotary drill operators. On average, 20 to 25% of the samples from these occupations exceed the TLV (MSHA, 2001). The NIOSH research program is addressing these silica issues by quantifying dust levels at major sources in the underground crushed and broken limestone industry.

Silica (SiO 2, CAS No. 7631-86-9) is found in abundance in nature. Pure crystalline silica that is not combined with any other elements is called free silica. When combined with other elements, the compound is called silicate. Free silica occurs in different polymorphic forms like quartz, cristobalite, tridymite, and tripoli.

Learn about crystalline silica (quartz dust), which can raise your risk of lung cancer. Crystalline silica is present in certain construction materials such as concrete, masonry, and brick and also in commercial products such as some cleansers, cosmetics, pet litter, talcum powder, caulk, and paint.

According to the National Cancer Institute, crystalline silica is an abundant natural material found in stone, soil, and sand as well as concrete, brick, and mortar. Crystalline silica from quarry is “respirable,” meaning people can breath it in. When inhaled, according to the NCI, the particles can penetrate deep into a person’s lungs.

Common sources of exposure to silica dust include cutting, sawing, drilling, and crushing concrete, brick, ceramic tiles, rock, and stone products. When inhaled, silica particles become trapped in the lungs and damage the tissue. The lung tissue scars and forms small rounded masses called nodules.

breathing dangerous levels of Silica are referring to Crystalline Silica, not Amorphous Silica. While the Federal NIOSH airborne limit for the very dangerous Crystalline Silica is only 0.05mg/m3, the IDLH on Amorphous Silica is a whopping 3000mg/m3, which is 60,000 times higher than Crystalline Silica.

Fact 1: It is not the crystalline silica that is the concern of OHSA or the California Prop 65 legislation. It is the ''respirable'' portion of that material – the tiniest of particles that can get deep into your lungs. These are generally created when sand is crushed or pulverized or used in sand-blasting operations.
