Silicosis, a severe and often fatal lung disease caused by inhaling crystalline silica dust, has long been recognized as a workplace hazard. Yet, despite this knowledge, new outbreaks continue to emerge across the United States, particularly among coal miners in central Appalachia and countertop fabrication workers. These workers are dying from a preventable disease, raising urgent questions about regulatory failures and industry resistance to change.

In central Appalachia, coal miners are developing black lung disease at younger ages than ever before. Dr. James Brandon Crum, a radiologist in eastern Kentucky, has been at the forefront of identifying this epidemic. More than a decade ago, he drove three and a half hours to a National Institute for Occupational Safety and Health (NIOSH) meeting in West Virginia to alert researchers to the alarming rise in complicated black lung cases. Since then, he has identified hundreds more cases, highlighting the severity of the issue.

The 2024 Mine Safety and Health Administration (MSHA) silica dust rule was designed to address this crisis by reducing the permissible exposure limit for silica dust from 100 to 50 micrograms per cubic meter. However, industry groups have launched legal challenges to overturn the rule, arguing that it imposes unnecessary restrictions and fails to account for operational variability. The National Stone, Sand & Gravel Association (NSSGA) and the American Exploration & Mining Association (AEMA) have both joined these efforts, despite acknowledging the need to lower the exposure limit.

Meanwhile, countertop fabrication workers are also facing a growing crisis. These workers, who cut, grind, and polish engineered stone products, are exposed to high levels of crystalline silica, leading to silicosis and, in some cases, death. A recent study published in the New England Journal of Medicine found nearly 600 cases of silicosis among California countertop workers, including 65 who required lung transplants and 31 who died. Despite a 2016 OSHA rule aimed at protecting these workers, industry groups have challenged its implementation, arguing that the stricter exposure limits are not based on sound science.

Public health experts like David Michaels, a former assistant secretary of labor for OSHA, argue that the problem is not just about regulation but also about the nature of the products being used. Engineered stone slabs can contain up to 90% silica, making it nearly impossible to produce them safely without significant changes to the industry. Michaels has called for a ban on the sale of such products with high silica content, citing the availability of safer alternatives.

Despite the clear evidence of preventable harm, regulatory action has been slow. The 2024 MSHA rule has been stayed by a court, and the industry continues to push back against enforcement. Meanwhile, the number of cases continues to rise, with NIOSH reporting that one in three coal miners in central Appalachia now has black lung disease. Dr. Crum emphasizes that the only thing higher than the black lung rates is the amount of excuses from those in power.

The ongoing crisis underscores a broader issue: the failure of regulatory systems to protect workers from preventable occupational diseases. As public health experts continue to advocate for stronger protections, the question remains: why are workers still dying from a disease that is both known and preventable?
