OSHA Silica Standards – What You Need To Know

The Occupational Safety and Health Administration (OSHA) has issued a final rule to curb lung cancer, silicosis, chronic obstructive pulmonary disease and kidney disease in America’s workers by limiting their exposure to respirable crystalline silica. This relates to the concrete polishing industry, the exposure limits of silica found in oncrete, mortar, overlay products, terrazzo, stone, brick, grout, stucco, thinset, rock, block self-levelers, color hardener, etc. must comply in the following ways:
  • •Permissible Exposure Level (PEL): 50 micrograms per cubic meter of air, averaged over an 8-hour shift
  • •Action Level (AL): 25 micrograms per cubic meter of air, averaged over an 8-hour shift

For the Construction industry, September 23, 2017 is the date you must be compliant with this regulation.
