Pioneering work by NIOSH and the National Industrial Sand Association (NISA) over the last 35+ years helped substantially reduce worker exposures to respirable silica. NISA's Silicosis Prevention Program coupled with the NIOSH "Dust Control Handbook" offer time-tested ways to protect workers and bystanders alike from silica dust in mines.

Thanks in large part to the STEPS Network on a national and regional basis, O&G is leading the way to providing a range of solutions for substantially reducing respirable crystalline silica exposures in workers and bystanders during hydraulic fracturing. Over the past 18 months, the O&G industry has created products & services that cover the full range of OSHA's hierarchy of controls (Elimination/Substitution, Engineering Controls, Administrative/Work Practice & PPE.)
Part I – Physical Reasons Why Engineering Controls Cannot Provide 100% Containment of all Crystalline Silica
BELLWOOD, PA, October 10, 2013 — The Mobile Air Shower by HalenHardy (MASHH), which removes hazardous crystalline silica from workers clothes during industrial operations, won the inaugural Ben Franklin Shale Gas Innovation & Commercialization Center (SGICC) Environmental, Health and Safety Award at the Shale Insight Conference.
Major reasons that engineering controls alone are not enough to protect workers from respirable crystalline silica
- Respirable crystalline silica is nearly as light as air and has a very slow "settling rate"...it takes a long time to drift to the ground.
- Because of the low settling rate, respirable crystalline silica can't be completely contained and is impossible to eradicate
September 4, 2013 -- HalenHardy LLC is pleased to announce the addition of Bob Glenn as Chief Scientist. Bob is one of the world’s leading experts on occupational lung diseases and the health effects of mineral dust exposures, and was largely responsible for developing and helping guide the silica mining industry’s successful Silicosis Prevention Program (SPP). Bob’s professional career includes:
Nearly two decades in the making, OSHA announced on Friday, August 23, comprehensive rulemaking on Crystalline Silica Exposures for General Industry, Maritime and Construction (the Mine Safety and Health Administration is anticipated to announce similar rulemaking in December).
With nearly 800 pages posted about crystalline silica on the OSHA website, we have not had time to analyze the proposal in any detail. However, we will offer a high-level analysis of the main provisions based on our preliminary review.
OSHA made the following comments in their August 23, 2013 release concerning their proposed respirable silica rule making,
