Crystalline Silica Online Course


Crystalline Silica is a common mineral that can be inhaled via dust particles caused by chipping, cutting, drilling or grinding. An estimated 2 million workers in the U.S. are exposed to silica in the workplace, which can lead to Silicosis. In this OSHA's Silica in Construction Course, workers will learn how to protect themselves from the dangers of crystalline silica dust. Specifically, it covers 29 CFR 1910.1053, OSHA's respirable crystalline silica training for General Industry.

Safely Protect Yourself and Your Workers from Crystalline Silica Dust in the Workplace

In this Crystalline Silica Online Course, you will learn:

  • Tasks that could result in exposure to crystalline silica
  • Health hazards caused by silica exposure
  • Labels, safety data sheets and signs relating to silica
  • OSHA’s required medical surveillance program


The crystalline silica employee training takes approximately 30 minutes to complete.


Participants must achieve a mark of 80% or higher to earn their certificate of completion. Those that do not reach the required mark will be allowed to repeat the course two additional times.

Certificate of Completion

Participants who successfully pass the Crystalline Silica Online Course will earn a certificate of completion which they can print out or download for their records.

Which materials can contain crystalline silica?

Many common materials in construction and manufacturing contain silica, including:

  • Asphalt
  • Brick
  • Cement
  • Concrete
  • Drywall
  • Grout
  • Mortar
  • Stone
  • Sand
  • Tile

Tips to help prevent the development of silicosis:

  • Know the dangers of breathing in crystalline silica dust, and avoid working in or near dust whenever possible.
  • Remember: Even if you cannot see dust, you may still be at risk.
  • Use water spray systems and proper ventilation in confined spaces.
  • If water systems and ventilation are not enough, your employer must provide respirators specifically designed to protect against crystalline silica.
  • Take advantage of health and lung screenings offered by your employer.
  • Thoroughly wash your hands before eating or drinking in dusty areas.
  • Shower and change into clean clothes before leaving work to help prevent contamination of your car or home.
