OSHA UPDATE: 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. About 2.3 million workers are exposed to respirable crystalline silica in their workplaces, including 2 million construction workers who drill, cut, crush, or grind silica-containing materials such as concrete and stone.

Key Provisions


  • Reduces the permissible exposure limit (PEL) for respirable crystalline silica to 50 micrograms per cubic meter of air, averaged over an 8-hour shift.
  • Requires employers to: use engineering controls (such as water or ventilation) to limit worker exposure to the PEL; provide respirators when engineering controls cannot adequately limit exposure; limit worker access to high exposure areas; develop a written exposure control plan, offer medical exams to highly exposed workers, and train workers on silica risks and how to limit exposures.
  • Provides medical exams to monitor highly exposed workers and gives them information about their lung health.
  • Provides flexibility to help employers — especially small businesses — protect workers from silica exposure.


Compliance Schedule

Both standards contained in the final rule took effect on June 23, 2016, after which industries have one to five years to comply with most requirements, based on the following schedule:

Construction - September 23, 2017. OSHA delayed enforcement in order to conduct additional outreach and provide educational materials and guidance for employer. See the memorandum. (per 9/20/17 memorandum, during the first 30 days of enforcement, employers who OSHA determines are making a good faith effort to meet the new standard will be assisted by OSHA in meeting the new requirements to assure understanding and compliance)
