Need To Know About New OSHA Silica Dust Rules and Regulations?

Posted on Friday, August 4th, 2017 by Mila Adamovica

The U.S. Department of Labor first emphasized the life-threatening hazards of respirable crystalline silica in the 1930s. Today, according to OSHA, approximately 2.3 million Americans are exposed to silica on a regular basis in the workplace.

Heavy equipment operators, construction, and plaster/drywall workers are the most at risk to being exposed to silica. The most severe exposures to crystalline silica result from abrasive blasting. Additionally, exposures may occur in cement, brick, and asphalt pavement manufacturing, ceramic manufacturing, and the steel and foundry industries.

Inhaling silica dust causes silicosis and lung cancer. The symptoms of silicosis include shortness of breath, chest pain, and difficulty in breathing, however, this illness can show no symptoms for many years. These non-reversible lung diseases are the target of the new OSHA silica regulation.

On March 2016, OSHA issued a FINAL RULE to protect American workers, limiting their exposure to respirable crystalline silica.

Final Rule’s Key Provisions:

  • Sets a new PEL (permissible exposure limit) for respirable crystalline silica to 50 micrograms per cubic meter of air, over an 8-hour shift.
  • Requires employers to use engineering controls (such as water spray systems or ventilation) to limit workers exposure to the PEL; provide respirators when engineering controls are not able to eliminate exposure; limit worker access to high exposure areas; develop a written exposure control plan, and train workers on silica risks and on the ways to limit the exposure.
  •  Employers must support and provide the means for potentially highly exposed workers to obtain medical exams to monitor their health in relation to the exposure.

The final rule took effect on June 23, 2016. However, OSHA’s memorandum has delayed the enforcement of this rule in order to provide additional guidance for employers. The rule is comprised of two standards: one for Construction and one for General Industry and Maritime. These industries have 1-5 years to comply with the requirements according to the following schedule approved by OSHA:

  • Construction – September 23, 2017.
  • General Industry and Maritime – June 23, 2018.
  • Hydraulic Fracturing – June 23, 2018, for all provisions except Engineering Controls (a compliance date: June 23, 2021).

The implementation of this rule will prevent about 900 new cases of silicosis each year, and save 600 lives.
