Crystalline silica is a naturally occurring mineral found in many construction materials, and more than two million workers are exposed to it each year. When tasks such as cutting, drilling, grinding, or crushing materials release respirable silica dust, workers may inhale particles small enough to reach deep into the lungs—causing severe long-term health effects. This course explains the risks associated with crystalline silica exposure and outlines the requirements of OSHA’s Respirable Crystalline Silica Rule for Construction (29 CFR 1926.1153).

Learners explore how exposure occurs, what health hazards exist, and how employers communicate risks through labels, safety data sheets, and signage. The training also introduces exposure control measures—such as engineering controls, Table 1 methods, respiratory protection, housekeeping requirements, and written exposure control plans. The role of a competent person and the importance of OSHA’s required medical surveillance program are also covered. By the end of the course, participants will understand how to reduce exposure and work safely on silica-related tasks.

Respirable crystalline silica is one of the most dangerous—and preventable—hazards in the construction industry. Understanding where silica exists, how exposure limits are regulated, and what control methods are required helps workers make informed, safer decisions. This course provides essential knowledge to help workers protect themselves and comply with OSHA’s silica standard.
