Respirable crystalline silica dust may be in the air without a visible dust cloud. Use adequate exhaust ventilation and dust collection to reduce respirable crystalline silica dust levels to below the permissible exposure limit (“PEL”). Maintain and test ventilation and dust collection equipment. Use all available work practices to control

The OSHA PEL for crystalline silica as tridymite or cristobalite is one- half of the OSHA PEL for crystalline silica (quartz). Appropriate engineering controls:
Products contain crystalline silica and therefore are classified as STOT RE2 according to criteria defined in the Regulation EC 1272/2008 and harmful according to criteria defined in Directive 67/548/EEC due to the potential to generate respirable dust.
reduce respirable crystalline silica dust levels to below the occupational exposure limit. Use all available work practices to control dust exposures, such as water sprays.
Accelerated silicosis results from exposure to high levels of airborne respirable crystalline silica, and usually occurs within 2 to 10 years of initial exposure. Accelerated silicosis causes decreased lung function and can result in heart disease secondary to the lung disease.
The OSHA PEL for crystalline silica as tridymite or cristobalite is one- half of the OSHA PEL for crystalline silica (quartz). New OSHA PEL from 2016 Respirable Crystalline Silica Standard – see Effective Dates below.
