Silica exposure is a threat for approximately 2.3 million US workers and is especially dangerous for more than 100,000 workers who make up the nation's stonecutters, foundry workers, sandblasters, and rock drillers. Crystalline silica is classified as a human lung carcinogen and is known to cause respiratory diseases, including an especially damaging one – silicosis. Effective measures are available to protect workers from exposure and to reduce and prevent its potentially devastating health effects. It's important that employees recognize the potential hazards of silica exposure so they can protect themselves. This course covers hazard recognition, potential health threats, exposure prevention, and control measures and focuses on construction-specific requirements as promulgated in 29 CFR 1926.1153. This course was developed with subject matter support provided by EnSafe Inc., a global professional services company focusing on engineering, environment, health and safety, and information technology. Please note, the course materials and content were current with the laws and regulations at the time of the last expert review, however, they may not reflect the most current legal developments.
