Silica Dust Control Coating for Frac Sand. In 2016 the Occupational Safety and Health Administration OSHA revised the permissible exposure limit PEL for respirable crystalline silica dust in hydraulic fracturing operations downward from 0.1 mgm 3 to 0.05 mgm 3.This PEL presents a challenge to the oil and gas industry since existing mechanical and personal protective equipment PPE
Silica is the trivial name for the chemical compound silicon dioxide SiO 2.The term silica comprises all polymorphs of silicon dioxide. In geoscience literature the term silica also includes silicic acid H 4 SiO 4 which forms when silica polymorphs and silicate minerals are dissolved in water. Two groups of silica polymorphs can be distinguished by their molecular structure
