Protective Measures Against the Silicosis Epidemic

In recent years, the silicosis epidemic among artificial stone fabrication workers has prompted significant action from medical professionals and governmental authorities worldwide. These efforts aim to raise public awareness, implement protective regulations, and ultimately curb the alarming rise in silicosis cases stemming from exposure to respirable crystalline silica dust. Here’s an overview of the proactive measures taken to address this pressing health crisis:

Educational Initiatives and Public Health Campaigns

Medical professionals and health organizations have spearheaded numerous educational initiatives to shed light on the dangers associated with artificial stone and the resulting silicosis epidemic. For instance, the University of Minnesota Public Health Institute hosted a seminar titled “The Growing Silicosis Outbreak Among Engineered Stone Fabricators” on October 10, 2023, featuring Jenny Houlroyd from Georgia Tech SHES. This event is one of many aimed at informing both the public and professionals about the risks of working with artificial stone and the preventive measures that can be taken.

Similarly, Workplace Health Without Borders (WHWB) conducted a two-part webinar series in February 2023, titled “Engineered Stone Countertops: How Big is the Problem?”. These sessions provided valuable insights into the scope of the issue and discussed strategies for mitigating the risks associated with respirable crystalline silica.

Governmental and Regulatory Actions

On the regulatory front, significant strides have been made both in the United States and internationally. In a landmark decision, the Australian Government announced a comprehensive ban on the use, supply, importation, and manufacture of all artificial stone, effective July 1, 2024. This bold move highlights the severity of the silicosis epidemic and sets a precedent for other nations to follow.

In the United States, CAL-OSHA’s Occupational Safety and Health Standards Board has been proactive in addressing the crisis. Following compelling testimony from esteemed medical professionals like Dr. Jane Fazio, Dr. Robert Harrison, and Dr. Manijeh Berenji, as well as from affected individuals like Leobardo Segura-Meza, the board unanimously passed an emergency standard on July 20, 2023, aimed at protecting artificial stone workers from acute silicosis. The emergency standard reflects a significant advancement in workplace safety regulations, underscoring the urgency of mitigating silica exposure in the industry.

Moreover, on December 14, 2023, the board convened to vote on a Proposed Emergency Regulation regarding Occupational Exposures to Respirable Crystalline Silica, further demonstrating their commitment to addressing this public health threat.

Research and Analysis

Research plays a crucial role in understanding and combating the silicosis epidemic. In February 2023, Safe Work Australia published a Decision Regulation Impact Statement focusing on managing the risks of respirable crystalline silica at work. This comprehensive analysis contributes to the global body of knowledge on effective strategies for reducing silica exposure in the workplace.

Additionally, on December 11, 2019, the Center for Occupational and Environmental Health (COEH) & California Labor Lab, in collaboration with the California Department of Public Health and UCSF, hosted a seminar by Dr. Robert Harrison titled “Severe Silicosis in Engineered Stone Fabrication Workers – US and Global Perspectives”. This seminar provided a deep dive into the silicosis cases among artificial stone workers, offering both a domestic and international perspective on the epidemic.


The concerted efforts of medical professionals, governmental authorities, and health organizations to educate the public and implement protective measures against the silicosis epidemic are commendable. These initiatives not only raise awareness about the risks associated with artificial stone but also pave the way for safer working environments and better health outcomes for workers in this industry. As these efforts continue to gain momentum, there is hope for significant progress in the fight against silicosis and the protection of vulnerable workers worldwide.
