OSHA’S New Crystalline Silica Standard

What you need to know… 

OSHA’s new standards for silica in the workplace significantly reduce the permissible exposure limits (PEL). It’s estimated that tighter regulations on silica dust in the workplace will save over 600 lives and $8 billion in associated costs.

Crystalline Silica Standard 29 CFR 1926.1153 applies to all exposures of respirable crystalline silica, except where exposure will stay below the OSHA action level of 25 ug/m3; 8-hour time-weighted average. 

Some examples of materials that are commonly involved under this standard include sand, concrete, mortar, block, terrazzo, natural stone, and thinset/grout/stucco/color hardeners.
