OSHA: New Respirable Silica Law and its Effects on Our Industry

John Jackson is the Application Technology Manager for Covia in The Woodlands, Texas. He holds a Bachelor of Science degree in Chemistry from Sam Houston State University. John has spent the last 8 years in research and development for proppants in the hydraulic fracturing industry. He has also engineered safer methods for handling crystalline silica so workers don’t inhale it in the field.

John serves as the Co-Chair for the American Petroleum Institute 19 C group that writes the standards for "measuring proppants used in hydraulic fracturing and gravel packing operations" which was published in August of 2018. He has also served 5 years on the Board of Directors for the Society of Petroleum Engineers Gulf Coast Section, where he received a Section Service Award and his Newsletter team was awarded Committee of the Year. John will also be serving as Distiguished Lecture for the 2019-2020 SPE year.

Crystalline silica is a major component of hydraulic fracturing, with about one million pounds of silica sand proppant used in a typical horizontal well completion. Multiple proppant transfer points can generate high concentrations of airborne silica dust, from offloading trucks to pumping downhole. Proper engineering controls that will be mandated by OSHA in 2021 will need to be implemented to mitigate exposure and keep employees safe.

A study was conducted at multiple hydraulic fracturing sites to determine if silica concentrations could be reduced below OSHA’s new Permissible Exposure Limit (PEL) of 0.05 mg/m3 averaged over an 8-hour period using engineering controls. Ideally, such controls would not have an onsite footprint as space might be limited.
