Countertop Workers Are Dying From Quartz Dust
🤖 AI Generated ImageTyler Jordan was 31 years old when doctors told him his lungs were failing. He had spent years cutting quartz countertops in his family's fabrication shop in Colorado. The dust from those slabs had settled into his lung tissue and was slowly destroying it.
He is not alone. More than 480 countertop workers in California have been diagnosed with silicosis since 2019. At least 30 have died. At least 100 have undergone or are awaiting a lung transplant — a procedure that extends life but does not cure the disease.
What Makes Engineered Stone Different From Granite or Marble
Silicosis is not new. It killed tunnel workers in West Virginia in the 1930s and miners for generations before that. What is new is the material causing it.
Engineered stone — marketed widely as quartz — is manufactured from crushed quartz bound with resins and pigments.
Unlike marble, which contains little crystalline silica, engineered stone can contain up to 95% crystalline silica by composition.
When workers cut, grind, or polish it, billions of nano-sized particles are released — small enough to bypass the lung's natural filters and lodge permanently in tissue.
According to epidemiologists David Michaels of George Washington University and Dr. Robert Harrison of UC San Francisco, who study occupational lung disease and wrote about the crisis for The Conversation in June 2026, complying with current federal OSHA standards is not sufficient to prevent silicosis from engineered stone. The particles are more toxic than the regulation was designed to address.

In May 2026, a Denver jury awarded $17 million to Tyler Jordan, finding that Cambria Co. LLC had misrepresented the harm of its product. In August 2024, a Los Angeles jury awarded a countertop worker $52.4 million in the first silicosis verdict against engineered stone companies. More than 370 lawsuits have been filed.
At the same time, the Protection of Lawful Commerce in Stone Slab Products Act — introduced by Rep. Tom McClintock (R-Calif.) — is moving through Congress. The bill would largely shield manufacturers and distributors of engineered stone from civil lawsuits.
A January 2026 House Judiciary subcommittee hearing debated the legislation, according to KFF Health News. Supporters argue manufacturers cannot be liable for fabrication shops that fail to follow safety rules. Critics say it eliminates the only accountability mechanism currently working.

The Regulation Gap That Is Making This Worse
OSHA first adopted silica limits in 1971, based on research from mining and foundry work. The 2016 update does not distinguish between natural stone and high-silica engineered quartz. Michaels and Harrison argue the federal standard was never calibrated for a material with silica concentrations this high.
California is the only state actively tracking the disease. The national case count is almost certainly larger — not because the disease is less prevalent elsewhere, but because other states do not require it to be reported.
NPR's reporting on the crisis found that at least 25% of fabrication shops continue to dry-cut stone without dust controls. Home Depot, Lowe's, and Costco continue to sell crystalline silica-containing engineered stone as of June 2026. Ikea stopped in 2025. Australia has banned importation and use entirely.

Britain issued new guidance in May 2026 banning dry cutting of engineered stone and announced inspections of 1,000 fabrication shops. California's OSHA is now considering a full ban on cutting the material, after researchers found that even shops with dust controls measured unsafe airborne silica levels.
The United States has not moved at the federal level.
Dr. Robert Blink, an occupational medicine specialist and former president of the Western Occupational and Environmental Medical Association, has described the pace of new serious illnesses and deaths as impossible to tolerate. The workers most affected are predominantly young, immigrant men in small shops with limited safety infrastructure and, until the recent verdicts, limited legal recourse.
Jordan's case was one of the first to reach a jury. The outcome of the McClintock bill will determine whether those that follow him can do the same.
Key Takeaways
- More than 480 countertop workers in California have been diagnosed with silicosis since 2019; at least 30 have died, and 100+ are awaiting lung transplants.
- Engineered stone can contain up to 95% crystalline silica — far higher than granite or marble and beyond what current OSHA standards were designed to regulate.
- A Denver jury awarded $17 million to worker Tyler Jordan in May 2026; earlier verdicts total over $69 million against manufacturers including Cambria and Caesarstone.
- The Protection of Lawful Commerce in Stone Slab Products Act (Rep. McClintock, R-Calif.) would largely eliminate civil liability for manufacturers.
- Ikea stopped selling engineered stone in 2025; Australia has banned it entirely; Home Depot, Lowe's, and Costco still sell it in the US.
- California is the only US state tracking silicosis — experts say the national case count is significantly higher than official figures.
