Employee exposure to silica dust generation during hydraulic fracturing operations is a continuing concern for the oil and gas industry. The shipping and transfer of frac sand (proppant) generates silica dust and hence poses significant environmental, health and safety (EHS) challenges to the industry.
Crystalline Silica recommending that occupational exposure to respirable crystalline silica be controlled so that workers are not exposed to concentrations greater than 50 micrograms per cubic meter of air (50 µg/m3) as a fullshift sample for up to a 10hr workday during a 40hr workweek to prevent silicosis.
Why is Silica Hazardous? Silica, often referred to as quartz, is a very common mineral. It is found in many materials common on construction and oil gas sites, including soil, sand, concrete, masonry, rock, granite, and landscaping materials.

OSHA mentions two types of silica in the standard, but the main emphasis is on crystalline silica, which exists as quartz, cristobalite, and tridymite. Businesses that use sand, like in the industry and the ceramics industry, need to be concerned because sand used in the process is 90% quartz.
The term "sandblasting" may be commonly used, but the more accurate word is "abrasive blasting." Although sand may have been used 20 years ago, safer blasting agentscommonly garnet, glass beads, aluminum oxidelargely have replaced silica sand because the dust in silicabased abrasives can cause serious lung damage and other health problems.
