On January 14, 2026, Professor David Michaels, former Assistant Secretary of Labor for OSHA and a leading voice in occupational health, issued a stark warning to Congress: a deadly, preventable epidemic of silicosis is sweeping through the artificial stone fabrication industry in the United States. This crisis is directly tied to the production of popular crystalline silica quartz artificial stone countertops.
While these sleek, modern surfaces appear harmless in American homes, the U.S. workers who fabricate them are paying an unimaginable price.
The Human Cost of Quartz Countertops
Artificial stone silicosis develops when workers inhale nano-sized particles of respirable crystalline silica, toxic metals, and toxic resins—particles released in lethal quantities when crystalline silica artificial stone is fabricated.
Key Health Impacts
According to the testimony:
- Nearly 500 confirmed silicosis cases in California, and many cases in other U.S. States as well.
- 27 confirmed deaths
- 52 lung transplants
- Workers often diagnosed in their 30s and 40s
- Significant underreporting
Symptoms worsen over time—from chronic coughing and shortness of breath to reliance on oxygen and, ultimately, premature death.
Silicosis is uncurable. Fatal. And entirely preventable.
Other Countries Acted. The U.S. Has Not.
Australia faced the same crisis and chose action over artificial slab industry pressure. In 2024, it banned artificial stone containing more than 1% crystalline silica. The results were immediate and striking:
Slab manufacturers and distributors shifted to virtually identical silica‑free alternatives like recycled glass artificial stone slabs containing non-toxic amorphous silica
- Workers kept their jobs without sacrificing health
- Retailers continued to offer beautiful, modern countertop options
- The industry remained profitable
Meanwhile, in the U.S., manufacturers (mostly foreign) are seeking immunity from lawsuits rather than manufacturing and selling safer materials—leaving workers increasingly vulnerable.
Why OSHA Regulations Are Not Enough
Professor Michaels noted that OSHA cannot keep up:
- Only 1,802 inspectors oversee 8 million workplaces
- It would take 185 years to inspect every workplace once
- Over 50% of fabrication shops have silica levels above the OSHA PEL
- The OSHA PEL is not a safe level anyway, but rather is a regulatory compromise.
Small shops lack the resources for multi-million-dollar dust control systems, making safe human fabrication of crystalline silica artificial stone impossible.
The Only Effective Solution: Eliminate the Hazard
Decades of occupational health science are clear:
According to the NIOSH Hierarchy of Controls, when a hazard cannot be safely controlled, it must be eliminated or substituted.
Safer Alternatives
Safer alternatives to crystalline‑silica engineered stone already exist:
- Recycled glass slabs made with non-toxic amorphous silica rather than toxic crystalline silica
- Porcelain and sintered stone
- Traditional natural stone with much lower crystalline silica content that is much larger in size (and thus not respirable)
These alternatives have the same look, feel, and price point—without the deadly risk.
A Crisis of Human Impact
Behind the testimony are real people:
Parents unable to lift their children.
Young workers with fatal disease awaiting lung transplants.
Families losing income, stability, and loved ones.
Taxpayers absorbing the cost of medical care.
This crisis is not inevitable. It is the direct result of choices—and those choices can change.
Demand Safer Products, Protect Lives
You can help drive meaningful change:
- Support recycled glass and natural stone countertop options
Encourage builders, retailers, and consumers to choose safer materials.
- Oppose legislation that shields foreign artificial stone manufacturers from accountability
Laws like H.R. 5437 would worsen the crisis, not solve it.
- Share this information
Most consumers have no idea their countertops may be linked to preventable deaths.
- If you are in the building trades or fabrication industry, switch to safer materials now
You can protect your workforce without sacrificing quality or revenue.
Worker Safety Can’t Wait, Fight with Us
The silicosis crisis tied to artificial stone is a public health emergency hiding in plain sight. Unlike the surfaces they create, the lives of these workers are anything but replaceable.
At Brayton Purcell LLP, we’ve spent decades fighting for workers harmed by toxic exposures. We stand with those suffering from this preventable epidemic and advocate for policies, and accountability, that put lives above profit.
