About the OSHA Silica Dust Standard James Hardie ProsWhat is Silica Sand with pictures wiseGEEK
OSHA requires employers to take specific actions to protect workers on construction sites based on the amount of silica dust they are exposed to The updated OSHA standard reduces the permissible exposure limit PEL for silica dust by about 80 from 250 μg/m³ to 50 μg/m³ over an 8 hour periodCrystalline silica commonly occurs in nature as the mineral quartz and is found in granite sandstone quartzite various other rocks and sand Workers who inhale very small crystalline silica particles are at risk for silicosis an incurable progressively disabling and sometimes fatal lung disease
